He serves as the famous guardian of Nekketsu High School against rival schools and is the captain of the school's dodgeball team.

Urabe asks Kunio where he's currently staying at, to which Kunio responds saying he's at Hotel Osaka, though questions why he's asking. Before getting an answer, Saori and Ōmi return in a panic and informs the group that their strategy has been leaked which lead to an ambush from the Union occurring in Namba. Ōmi then suggests that Izawa and Yoshihiro are likely being held captive by the Union. The Alliance then agree on all heading to Namba to get more information.

Later in Shinsaibashi, Kunio breaks the news that Miho was captured by the Union and that Urabe was a spy for them stating that he had a feeling that was the case. Saori asks where Miho was taken, though Kunio replies stating he's unsure which angers Izawa and leads him to attack Kunio until he is calmed down by Ōmi. Saori then suggests that Masaki may know about something about what's going on and informs Kunio that he rules over Ebisuchō. The rest of the Alliance feels reluctant in going through with the idea as they believe he'd have no interest in wanting to work with them, though Kunio states that he'll be going to Ebisuchō regardless. Yoshihiro later finds Kunio and tells him that he's managed to escape from the Union. Kunio questions what he plans on doing next, in which Yoshihiro claims that he's worried about the Nekketsu High School students and plans on returning back to the hotel.

Kunio asks for Masaki's location once again and is told that he's likely in Koshien. Kunio confronts Masaki at the Tiger Archives in Koshien and hands him the letter. Masaki grabs Kunio by the neck after reading the letter as he's unaware of who he is, though Kunio introduces himself and explains that he's working with the Alliance. He then listens to Masaki explain the Union's origins and how he dislikes what it became before asking Masaki why he chooses to still be apart of the Union. Masaki responds saying that his friends will be in danger if he defies the new leader which Kunio then mentions that Miho said the exact same thing. Feeling motivated, Masaki asks Kunio to leave Miho to him and hands him a bike key before leaving. Shortly after Masaki leaves, Kunio walks outside to the sight of some Union members waiting to attack him. The group believes that Masaki is going to get hospitalized with Yasuyuki also suggesting that Yoshihiro is likely already beating up the Nekketsu High School students at the hotel. Kunio questions why Yoshihiro would do such a thing, to which Yasuyuki reveals that Yoshihiro is the second leader of the Union and is aiming to get rid of the Nekketsu students.

He explains his motives in wanting to expand the Union's control into Tokyo and eventually the rest of Japan and then mentions that he transferred to Nekketsu High School in order to take Kunio out.

The group leaves after hearing the police sirens blare once again, though Kunio instead stares off into the sunrise. When asked by Miho if something was wrong, Kunio expresses that he could've turned out to be like Yoshihiro and thinks of it as something striking that they both did what they thought was right despite their differences. Miho suggests it's nothing to worry about as she believes that those are things to think about when they get older.

Later at the airport, Kunio is seen saying goodbye to the group as he gets ready to depart for Hong Kong alone as he believes that Madoka and Sabu's vendetta against him is his problem to deal with. The others express that they wish to accompany Kunio regardless which leaves him speechless and convinces him into letting the others join him. Before leaving to catch the plane, Shishiō and the rest of the Lion Alliance arrive at the airport to inform Kunio that they still plan on continuing their takeover of Tokyo as they wish to take on him and his crew once again.

Sabu brushes off the comments and claims that he still has an ace in the hole, though Ginjishi shows up with Madoka rescued which leaves him shocked. Sabu gets ready to shoot Madoka, however Ginjishi jumps in front of her to block the bullet. Enraged, Kunio vows to make Sabu pay for what he did and begins the fight against him and Lee.

River City Super Sports Challenge ~All Stars Special~[]

This remake of Super-Awesome Field Day re-imagines the events of that game. The story takes place after River City: Rival Showdown.

In the story mode, Kunio is first seen alongside Momozono, Sugata and Nanase congratulating the freshmen for passing the screening for the upcoming athletic meet. Kunio decides to place Noboru Takamine as the team's backup player as he realized that they're only supposed to have six members within a team. Takamine is initially upset by this, though Kunio assures that he can become a regular member of the team if his skills improve before the tournament. Kunio then briefly introduces himself to the new members and mentions that they'll be starting special training on the following day. On the next day, Kunio arrives at the school during the evening and asks what happened as he noticed the team looked worn out. He comes to the conclusion that Reihō Academy was behind what happened and becomes angry that they did such a thing in his absence, though also recognizes that the team's weak skills will not do and decides that going through intensive training will be the right course of action. Sugata is shocked and questions if he's asking them to train right then and there, to which Kunio confirms and demands that they run ten laps around the field with him. The team then passes out on the ground after hearing his demands.

Before the first qualifying round, Kunio is seen with Sugata, Takamine, and the new freshman as they notice injured players being taken on a stretcher mentioning bombs. The others come to the conclusion that the athletic meet isn't an ordinary tournament and are then informed by Momozono that bombs have falling from the sky. Kunio disregards the bombs and decides that they should still push forwards. After the match, Nanase is blackmailed by Koshiba and Nito at the park into handing a bottle of poison to Kunio as they threaten to go after his friend Matsuda. During the second match of the qualifiers, Riki finds Kunio and mentions Sugata's injury from the day prior. Kunio states that it's only a minor injury and expresses how odd the tournament feels. Riki believes that there is more to come and warns Kunio to be careful, though Kunio jokingly tells him that he shouldn't be saying something like that to his opponent. Riki then points out how it was pointless for him to worry and the two wish to have an honorable match against each other. With Hanazono High School beaten, Kunio is seen celebrating with the team and is suddenly handed the bottle of poison by Nanase disguised as a girl. Thinking that this was only a gift from a fan, Kunio taunts Hayato Ichijō for being able to receive gifts due to his popularity and takes a drink from the bottle. Kunio confusingly watches Ichijō run off after the girl due to his jealously. Shortly after leaving the school, Kunio and the new freshman witness Wataru being beaten up by Reihō students and manages to dissolve the situation. Kunio asks Wataru what he's doing and mentions that it would've been a better match with him present, to which Wataru appears shocked and disappointed that Riki lost the match. Unsure of what's going on, Kunio asks Wataru to stop bothering Riki before leaving.

From this point, Kunio is hospitalized due to the poisonous drink we was given though his team outside of Nanase is unaware of this. With everyone confused on his whereabouts, Tōdō makes a sudden change to the tournament's rules requiring that the team's captains are required to participate in the upcoming match and that teams without one will be disqualified. Tōdō then shows up to Nekketsu High School's booth and warns them that their team will have to be eliminated within the next five minutes after noticing Kunio was absent. With the team in a panic, Momozono decides that they'll need to select a new captain with the rest of the team all agreeing on appointing the new freshman. During the ending of the first match, Momozono informs the team of Kunio's condition. Later on, Hiroshi and the new freshman pass through the park onto the way to the hospital to visit Kunio, though they are stopped by Tōdō as he orders Ryūichi and Ryūji to attack the two. Nanase jumps in to back them up immediately while Hiroshi runs to alert Kunio of the situation. Throughout the fight a recovered Sugata and Kunio arrive as additional support. After the fight Kunio thanks Nanase for his efforts, though he looks away disappointed in himself as he explains to the team that he was the one responsible for hospitalizing Kunio and apologizes to them. Kunio expresses how he wishes to reveal what's going on right away, though decides that it'd be better for them to pay back Reihō Academy in the tournament. Nanase begins to apologize once again, though Kunio stops him and jokingly states he planned on going on a diet anyway. He then asks Nanase to stop feeling so down and to instead focus on beating Reihō.

During the semi-finals Kunio is seen with Sugata, Momozono and the new freshman as they discuss the remaining teams participating in the tournament. Having heard that Hanazono High School and the School Union are still in the tournament, Kunio playfully suggests that they go tease them as they won't be able to bear being defeated. Kobayashi, Reika Gojōin and Takashi Onizuka then return to gloat about their respective team's strengths which angers Momozono and gets Takamine to think about how their teams were previously undefeatable. Kunio thinks lightly of the situation and believes that they've all gotten stronger since then and that it'll be good payback for what happened during their practice match. After the match Kunio is seen celebrating their victory with Sugata and the new freshman as he points out how much stronger he's gotten in his absence. Kunio and the new freshman then meet up with Riki and Tsuyoshi Gōda at the School Union's booth and notices that it's been destroyed. After being informed of what happened, Riki asks if Nekketsu High School is participating in the finals, to which Kunio confirms that their team is still in. Riki then asks Kunio to not get defeated by Reihō, in which he responds by telling Riki to stop worrying about others and instead worry about his own team.

Before the finals the team is seen discussing Reihō Academy's remaining participants. Kunio optimistically notes the remaining teams as being a headache, though Hasebe suddenly enters the conversation as she went to see Kunio after hearing he was hospitalized. Hasebe expresses that she's glad Kunio is back in a healthy state and then mentions she was kicked out of the tournament's broadcasting room after suspecting something was off and was looking to prevent Tōdō from meddling with the tournament any further. She then states that Ryūichi and Ryūji has seemingly already dealt with Tōdō for the final game and notes that they didn't look like they were kidding about having a fair competition for the final game. With Kunio feeling pumped up, Hasebe begins to think that her worrying was needless and asks him to cheer up before leaving. Following the finals, Nekketsu High School is announced as the tournament's winners with Kunio crediting the new freshman as being half the reason for their team doing so well. Nanase appears confused and questions who the other half is, to which Kunio admits that he was referring to himself. With the tournament coming to a close, Kunio is then seen walking home with Hiroshi and the new freshman as they reflect on how chaotic things turned out to be.

During the secret exhibition match, Kunio is seen with Hiroshi, Kenichi Morimoto, and the new freshman discussing an invitation they received from Tobioka challenging Nekketsu High School's team against his own team. Kunio initially is suspicious of the invitation, though after hearing of the other participating teams he notes them as being names he's heard of in the past and happily decides to accept Tobioka's challenge. With Tobioka, Tōdō and Yamada's ulterior motives falling apart following Nekketsu's victory in the secret match, Kunio is seen walking home with the rest of the team as he stops and personally thanks the player for playing the game. Kunio then catches up with the rest of the team as Momozono warns him that they'll miss the train.

Kunio appears as the captain of Nekketsu High School's team and additionally as a captain for the Nekketsu Dodgeball Club team, the Historical Drama team in the role of Kunimasa, and the Nekketsu Magical Story team in the role of Kounie. In the story mode, the player's custom character replaces Kunio as Nekketsu's team captain after he is temporarily removed from the team. His other team counterparts are able to be played outside of the story mode. Kunio is able to use Mach Kick and the Nuts Shot, Dodgeball Kunio is able to use the Penetrating Shot and the Nuts Shot, Kunimasa is able to use Mach Kick, and Kounie is able to use Mach Bash and Mach Kick.

During the night time, Kunio is offered party tickets once again by another student and gets in a scrap between them after declining the offer.

On Reihō's campus, Kunio checks in on an unstable Onizuka who suddenly picks a fight with him. After being defeated, Onizuka is briefly seen in a normal state as he recognizes Kunio, though this doesn't last long as he begins to mumble again which creeps Kunio out. At the Starpark Café, Kunio meets Akira Shinoda and takes a seat to listen in about the stories and information he has regarding Reihō Academy.

On the second day, Kunio meets Minamoto under the Hanazono Bridge as told and fights him in order to get the information he's looking for. Minamoto brings up the rumors spreading around of Ryūichi and Ryūji's takeover of all the other high schools in Japan and then asks him to take down Kiyofumi Taira as he believes only Kunio can stop him from instigating a fight between Hanazono High School and Senridai High School. Kunio initially brushes the situation off as he knows that Hanazono has Riki, though he agrees to help out after being told by Minamoto that Taira plans to do the same thing to Nekketsu High School and that he was responsible for the previous day's attack on him. Kunio is then told to find Taira's men at the Hanazono Park within the next hour. Later at the park, Kunio fights against Taira's crew and then learns from Minamoto that Taira has switched to his backup plan of attacking Riki directly.

Kunio in the fight against Tadashi Kinoshita.

In the evening, Kunio comes across Sugata knocked out inside of Maruka Transport and immediately comes to his aid. After realizing who Sugata was referring to as his assailant, Kinoshita attempts to get the drop in on Kunio and attacks him from behind. Kunio proceeds to fight Kinoshita two times until Sawaguchi and Nishimura arrive to assist him. The two initially appear disappointed that Kunio already handled things by himself, though Kinoshita gets up for a third time and attempts to attack Kunio once more. After Kinoshita calls in his boys, Kunio fights him with the help of Sugata, Sawaguchi, and Nishimura. Upon being defeated, Kunio and Sugata get ready to leave the warehouse but are stopped after hearing the sound of Kinoshita getting up. Kunio then steps back and uses a special move to keep him down for good. Later at the Starpark Café, Kunio gets ready to talk to Shinoda again though is eventually told by him to talk to his old classmate Rina Deguchi at Three Castle if he wants to hear more high school stories. Unsure of what the place is, Kunio asks what Three Castle is about, to which Shinoda describes the place as being similar to a maid café where the girls instead wear princess gowns instead. With Kunio still confused on what the point of such a place is, Shinoda explains that people pay a thousand yen to talk with the girls for an hour which immediately shocks Kunio that people would pay such a high price to have girls talk to them. After wrapping up the conversation, Shinoda pays for Kunio's visit and lets Rina know that he's coming so he's able to get inside the building. Due to Rina being busy, Mika comes to sit with Kunio instead and asks if he'd like to talk to her. Kunio recognizes Mika's face and eventually points out that she was the Reihō student who asked him out the other day. Mika then drops the act and apologizes for what she did mentioning that she was hired by Taira for a gig. She attempts to change the conversation by asking Kunio if he'd like to go out on a real date, though Kunio shoots down the offer and lets her know that he's more interested in hearing about what Taira did. Mika is then suddenly called out before she got the chance to explain what happened which leaves Kunio frustrated. Rina comes to sit with Kunio and proceeds to tell him all about Kobayashi's backstory and who Onizuka is. After this, Kunio heads back into Three Castle to talk with Mika once again. Through her, he learns that Mika was tricked into getting on board with Taira's scheme and that his money comes from a party ticket scam he's running.

On the third day, Hiroshi calls Kunio to warn him that Kamijō and Yamamoto are looking to have another fight in front of Yumemi Spa. The two have learned a tag-team move since their last encounter, though they are still beaten by Kunio. The two thank Kunio for continuing to fight them which leaves him confused. Kamijō claims that because they chose to take on such a legend, their fights have helped put their school on the map and that they hope they've become more popular with the girls at their school because of it. Although Kunio assures that he didn't intend on teaching them anything, he gives them credit for having guts which surprises Kamijō and Yamamoto as they immediately gain the motivation to hit the gym and continue their training. Outside of Reihō Academy, Kunio meets Kobayashi who demands to have a fight at his abandoned factory by evening. Kunio initially doesn't see why they'd need to fight, though Kobayashi forces him by threatening to launch an attack on Nekketsu High School if he doesn't show up. Outside of Kobayashi's factory, Mochizuki is seen waiting for Kunio to have a one-on-one rematch against him. Upon being defeated, Kunio is told by Mochizuki how Kobayashi is leagues above the other members of Reihō's Four Kings and that he'll go likely all out in a fight against him. Kunio then heads inside the factory where he is told by one of Kobayashi's men that Kobayashi is having doubts that Kunio is tough enough to take him on, so he decided to test him by having Kunio find and beat each member of his crew in a fight to get the required keys to open the door to the room that he is waiting in. After obtaining each of the keys, Kunio comes face to face with Kobayashi and is told of the factory's history and what Kobayashi's plans are. Kobayashi informs Kunio that he has no real interest in Reihō's takeover scheme and claims that someone above Ryūichi and Ryūji are truly pulling the strings in the operation. Kobayashi asks Kunio to return Reihō back to normal, though Kunio appears confused and questions why he doesn't do so himself. Kobayashi states that he is intrigued by watching the Four Kings work together on something so grand, but admits that he hasn't been heavily involved and decided to jump in at the point he did to see if he can bet on Kunio to return things back to normal. The two then proceed to fight each other with Kunio coming out on top. Kobayashi will then warn Kunio that the twins are leading an attack on Nekketsu High School the next day and that Gōda is currently waiting to meet him outside of Reihō. Before leaving the factory, he hears a sound coming from the other room and comes across Mami who has been captured by Taira.

Kunio meeting Tsuyoshi Gōda outside of Reihō Academy.

Outside of Reihō Academy, Kunio meets Gōda who immediately asks to have a fight with him. After being defeated, Kunio asks Gōda why he wanted to fight, to which he reveals that he was given orders by Reihō after his school went under their control. Kunio appears confused as to why someone as tough as him would take orders from them, though Gōda reveals that it was because they were threatening to go after his sister Saori Gōda. After hearing about Kunio, he decided to test his strength to see if he's worthy of taking down Reihō. Gōda passes out shortly after with Godai then arriving on scene in immediate distress seeing his friend knocked out. Kunio poorly attempts to de-escalate the situation, though Godai is too enraged to care and fights him for what he's done. Upon being defeated, Gōda wakes up and resolves the situation by explaining what happened between him and Kunio. Later at Starpark Café, Kunio is informed by Mami's friends that she was kidnapped once again by a pair of twins from Reihō as a message to Riki and that Hikaru Saotome is the only other person they have told so far. Saotome arrives on scene to check in on the girls and is surprised to see Kunio around. Kunio then asks Saotome to protect the girls before leaving. On Yumemi First Street, Kunio meets up with Godai who informs him that a girl is waiting for him at the arcade and that she has been asking Nekketsu High School kids about him. Kunio finds Mika at the arcade where he accidentally causes her to lose the crane game she was playing which angers her. Kunio pays back the yen she spent and after Mika wins her prize she mentions that his interest in Reihō's antics have made her remember Makoto Yamagami, someone who used to lurk around Kotobuki Road alongside a kid from Reihō that she was unable to remember the name of. She then leaves to get ready for work.

Kunio finding Mika Sakagami on the ground outside of Three Castle.

Later at night, Kunio witnesses a crowd surrounding Mika outside of Three Castle as she lays on the ground injured. Kunio rushes in to check on her and is told by Mika that she asked Makoto about a kid named Yamada which caused him to snap. Inside of Starpark Café, Kunio talks about what happened outside with Shinoda and the Barkeep until a mysterious figure breaks into the building in a rage. Kunio fights off the man and is bewildered by his strange behavior. After the fight, Kunio checks in on Shinoda and asks him to take himself to the hospital. Kunio heads into Three Castle afterwards to see Mika and instead meets Minori Yamagami where she informs Kunio that Mika has quit her job as things were getting too dangerous for her. Minori points out that the assailant's rage was likely triggered by something specific and then asks Kunio if Mika has ever told him anything about Makoto. Kunio then states that he was told Makoto and Yamada were once close, which Minori immediately claims to be the exact cause for why Makoto acted in the way he did. She begins to explain their history and how they ruled over Kotobuki Road together until their falling out. During the conversation, Rina rushes into the building and attempts to warn the two of Makoto's presence, though he follows her into the building and grabs her by the neck. Makoto gets ready to punch her, though Kunio steps in and grabs a hold of his fist before he's able to strike her. Kunio further enrages Makoto by mentioning Yamada's name which causes him to knock Rina up into the air. Kunio catches her and hands her off to Minori where he then asks the two to leave as he begins his fight against Makoto. Upon being defeated, Minori returns to comfort Makoto and apologizes to Kunio. She then asks him to stop by Starpark Café later so she can thank him for saving Rina and stopping Makoto. At the café, Minori reveals that Makoto is her twin brother and that he likely returned because he remembered who Yamada was. She explains that Makoto once told her that Yamada's reason for fighting was because he had unfinished business with the two then coming to the conclusion that he was referring to Kunio himself. Kunio gets ready to leave, though Minori stops him to give him a kiss which causes him to blush and float up into the air.

She then states that Mami is being guarded by Ryūichi and Ryūji on the top floor of the school and that she will keep an eye on the twins to make sure they don't harm her. Hasebe then hands Kunio a rice ball she made and wishes him good luck. Kunio then finds Riki at the entrance of the school and decides to team up with him knowing that he's there to rescue Mami.

Kunio and Riki then proceed to fight their way through the entire school and are assisted by their allies along the way. Following the rematch against Kobayashi on the school's top floor, he lets the two pass through where the twins wait for them. Kunio orders Riki to find Mami once they beat the twins and to get her out of the school. He states that Hasebe is currently with her and assures Riki that she likely has not been harmed. Riki then asks Kunio what he plans on doing after, to which Kunio states that he has to do something that's got to be done. The two then move in further where they come face to face with the twins and are told that they'll only be given Mami's whereabouts if they successfully beat them in a fight. The twins are successfully beaten with Hasebe then coming in to bring Mami back to Riki safely. Kunio then presses Ryūichi and Ryūji for information on why they got involved in the first place, though mentions that they were following orders of someone who's beaten them in a fight three months prior after not getting a response out of them. Now flustered, the twins continue to claim that they have no idea what Kunio is talking about, though Kunio then states that Yamada was the one who was pulling their strings. With Hasebe shocked and Riki confused on who he's talking about, Kunio briefly explains that Yamada was someone who he used to know. Hasebe is then able to come to a conclusion on how Yamada fits into the whole picture. The twins eventually let up and tell Kunio that he will be able to find Yamada on the rooftop. Kunio then heads up to fight Yamada alone as Hasebe escorts Riki and Mami out of the school.

Kunio disregards his speech and only comments about how he'll beat Yamada to a pulp. Yamada laughs his threats off and gets ready to put an end to Kunio and show him what he's learned since they last saw each other. Upon being defeated, Kunio listens to Yamada talk about how he's always hated the idea of losing to him, how his scheme was almost a success, and that he vows to come back stronger the next time they cross paths. Without saying a word, Kunio walks back inside to the sight of Hasebe, Riki, and Mami all waiting for him to be done as Hasebe was insistent that Kunio was going to win. The four then leave the school with Kunio stopping along the way to talk with all of those that helped him in this battle. While in the school's courtyard with everyone, Yamada unexpectedly comes back and hurts his allies in a surprise attack. Kunio orders Riki to bring Hasebe and Mami to safety as he goes to fight Yamada once more. He then listens to Yamada reveal his true intentions and that all of what he did was purely out of jealously. Kunio blocks an attack from Yamada with the help of his aura that protects him from Yamada's dark powers. Yamada asks Kunio if he's already fought Makoto, to which Kunio confirms that he did. Surprised that he recovered, Yamada reveals that he was the one who brainwashed Makoto and threatens to do the same thing to Kunio. The two then run towards each other as they fight one last time. Kunio bests Yamada in battle and witnesses the brainwashing ware off on him. Yamada explains that the dark power was supposed to give him the ultimate power, though admits that he never expected it would fail him when he needed it the most. Kunio questions why Yamada went to such extremes, to which Yamada struggles to remember his reasoning other than him coming across the dark power while being so consumed by the desire to defeat Kunio. He then begins to recollect on his memories of Kunio and why he grew to hate him so much. Kunio then asks Yamada if he's over his grudge, in which Yamada admits that being bested this time around felt good and that he plans on withdrawing from Reihō Academy. Kunio begins to think about what would've happened if they fought to the end back in middle school with Yamada thinking that they may have ruled over all the schools in Japan together.

Kunio RS SC 11

Kunio during the ending of Riki's Story.

In Riki's Story, Kunio instead spends the first three days going around town listening to people talk about strange events they witnessed involving Riki. On the final day, Kunio finds Riki on Reihō Academy's rooftop and questions why he's there. Kunio comes to the conclusion that he's there at the fortune teller's request when Riki explains that he's there to lift the belt of the strongest guy to the God of Yumemicho in order to find Mami. Kunio mentions how he's been hearing all about Riki being played by a fortune teller for the past three days and scolds him for not catching on that it was a sham. Ignoring his comments, Riki lifts his belt to the sky and begins listing off all of his wishes until he and Kunio are struck by lightning. Hasebe comes onto the rooftop with Mami while Kunio is left speechless. As Riki and Mami leave, Hasebe points out how Kunio is still putting himself on the line with Kunio asking how he knew he was there. Hasebe doesn't directly answer the question and states that him and Riki have made a mess of themselves and of the school, but notes the situation as being a happy ending regardless. Kunio then questions if he's still the main character of the story.

River City Melee: Battle Royal Special[]

River City Melee: Battle Royal Special makes many references to previous games in the franchise. Although the game states that it takes place right after ~All Stars Special~, the game is probably not canonical, as it contradicts many things from the new continuity started with Nekketsu Kōha Kunio-kun Special.

Kunio returns as the captain of Nekketsu High School's team, the captain of the Nekketsu Dodgeball Club team, the captain of the Jidaigeki team in the role of Kunimasa, and as the captain of the Nekketsu Magical Story team in the role of Cooney. Nekketsu High School's version of Kunio is able to use the Mach Kick, the Nut Shot, and the Fireball Spike. The Dodgeball Club version of Kunio is able to use the Spin Attack, the Nut Shot, and the Penetrating Shot. Kunimasa is able to use the Mach Kick, the Warp Shot, and the Human Helicopter. Cooney is able to use Sliding, Mach Strike, and the Hurricane Crash.

After the end of the previous athletic meet, a new tournament was announced. There have been rumors of frequent attacks against students in other schools. Some believe that these attacks are related to the tournament. Believing that something suspicious is brewing, Kunio asks Sugata to put together a team once more. Sugata angers Kunio, as once again he gathers the same team of freshmen, although he simply was unable to gather any seniors again. According to the rumors Kunio has heard, the attackers bear a resemblance to the Tiger Brothers, but as Kunio has previously fought them and personally knows them, he doubts it.

Kunio and his team eventually defeat all their opponents and get to face the Tiger Brothers, though he is sure that they are not involved with the attacks, he and the Tiger Brothers don't care and are only interested in fighting each other. Toraichi is aware that Kunio's teammates want answers, while Toraji considers them weak. After they defeat the Tiger Brothers, Kunio's teammates realize that it is impossible for the the Tiger Brothers to have been the attackers, though even they are unaware of who could have done it. Kunio then promises to clear their names. After the Tiger Brothers leave, Monji Sumi of Wu Wonfu arrives, annoying Kunio and the others due to his slow arrival.

Sumi reveals that he is responsible for the attacks near Nekketsu High School, as he and Kunio go way back. Though Kunio claims he has never met him, and due to the story taking too long and Sumi being annoying, Kunio decides to fight him immediately. After his defeat, Sumi reveals that a colleague of the friend of the brother of the wife of the brother of his friend was once defeated by Kunio. For this reason alone, he sought to destroy Kunio and Nekketsu High School once and for all. Kunio and his teammates want real details behind the attacks though, and that's when Yasuaki Tsubaki, the leader of Wu Wonfu, and it's remaining members of the group arrive.

Tsubaki explains Wu Wonfu's objective to Kunio and his teammates, but the real mastermind is revealed to be Yūji Munakata, an old enemy of Kunio who wanted revenge for his previous defeat, although Kunio barely remembers him. Yūji created the tournament for the sole reason to get back at Kunio and Riki. This annoyed Kunio, as he would have agreed to a simple one-on-one fight. Kunio's team is given the choice to be crippled or become loyal to Wu Wonfu should they lose. After Kunio defeats them, Yūji learns of the source of Kunio's strength and realizes that he cannot beat him. Yuji and the Wu Wonfu leave, but not before Tsubaki reveals that his series of books are part of the reward for winning the tourney. Tamae Nishino, the master of ceremonies, then arrives with the books. Although Nanase and Morimoto have no problems with the books, though the others are enraged. Nanase and Morimoto leave with Nishino before things get dangerous, as Kunio and the remaining members are pissed at the book's content. They then chase after Wu Wonfu to get revenge.

Kunio also appears in the stories of other teams. He, along with Wu Wonfu, acts as the leader and final boss for the Outlaw team. However, this turned out to actually be Kyōsuke Matsudo.

River City Girls[]

In this continuity, Kunio keeps many of the same characteristics that were part of his other depictions, though is made to be the boyfriend of Misako. Kunio and Riki serve as the main catalysts to the game's story. He is voiced by Greg Chun.

Kunio Riki RCG Manga SC

Kunio and Riki in a photo sent to Kyōko's phone.

During the beginning of the game, Misako and Kyōko receive a mysterious text while in detention that shows a photo of them supposedly being kidnapped. The girls run throughout all of town fighting anyone that gets in their way in search of any information on their whereabouts. Many faces they come across during their adventure, most notably their love rivals Hasebe and Mami, hint at or outright claim that the boys are not in love with Misako and Kyōko. The girls eventually reach the Sanwakai Tower thinking that their boss Sabu was responsible for the kidnapping of Kunio and Riki, though they'd eventually realize the Sanwakai had no involvement and would fight Sabu's daughter Sabuko as she wanted to set an example out of them for storming through the tower. The girls defeat Sabuko and kick her out of the window where they then crash into the sauna nearby. Inside of the sauna, Kunio and Riki are able to be seen together relaxing until they spot the girls.

In the game's bad ending, Kunio notes the two as being the crazy girls they've met before and struggles to remember their names. The two then leave with Kunio suggesting that they go see Hasebe and Mami. Enraged, the girls proceed to punch the boys out of the roof. In the game's true ending, Kunio appears confused as to what made the girls think they got kidnapped. As the boys get ready to leave, Kunio asks Misako and Kyōko if they'd like to join them on a burger date. Upon completing the game once, Kunio and Riki are both unlocked as playable characters. The story does not change with any of them present and will act as if they are not present.

River City Melee Mach!![]

Nekketsu High School's Kunio would have his Mach Kick replaced with the Mach Kick A, a variant of the move that has a fourth finishing strike. The player can follow it up with a jumping soccer kick by pressing the punch button after the final kick. When the Nut Shot is performed, the thrown item will now turn into a dodgeball. The Fireball Spike was visually changed to look similarly to how it did in Surprise! Nekketsu New Records! The Distant Gold Medal.

Although this is not listed in his special moves, Kunio is now able to perform the Nuts Shot when kicking the soccer ball on the soccer field stage.

Stay Cool, Kobayashi-san!: A River City Ransom Story[]

Carrying over from Rival Showdown, Kunio is able to gain experience that can be allocated to certain stats, equip armor, or gain special moves that can be changed to your liking. When playing in China Heroes, Kunio will have the Mach Kick, Nuts Shot, Tornado Kick, Fireball Spike, and the Green Dragon Crescent Blade.

Kunio gets ready to attack Hyperion with a chair, though Hyperion decides that he's a perfect fit for his tournament and teleports Kunio into his world.

When Kunio comes across Riki, he appears confused that he's also participating the tournament. Riki is interested in showing Kunio how strong he really is, to which Kunio laughs off the comment and begins to fight. Upon finding Tunestone, he's confused that a student is participating in the tournament and questions if Kunio should be at school, though Kunio questions if Tunestone should be having skin, which leads to an awkward pause before Tunestone admits that he doesn't have a comeback. On the final fight, Hyperion is impressed by Kunio's strength but believes that it still won't be any match for him. Kunio warns Hyperion that he hasn't seen what he's capable of yet.

Localized versions[]

  • In Renegade, Kunio was changed to a nameless vigilante who had to rescue his girlfriend from a gang of thugs. The NES version of the game gives him the name Mr. K.
  • In the NES version of Super Dodge Ball, Kunio was named Sam, a captain of Team USA.
  • In River City Ransom, Kunio is known as Alex. His full name is expanded to Alex Kun in River City Ransom Underground.
  • In Crash 'n the Boys: Street Challenge, Kunio was named Jeff "Crash" Cooney, a captain of Team Southside High School.


  • He is named after Technōs Japan's former president, Kunio Taki.
  • Kunio has no surname. The closest he has had to a surname is Oyama, due to second Oyama brother in Double Dragon 3: The Rosetta Stone being named Kunio. In the TV drama, he is given the surname Fu'unji (風雲児).
  • Kunio is the only character whose name was not mixed up in Nintendo World Cup.
  • Kunio's birthday is on November 27, the same as Bruce Lee. Kishimoto choose this date in order to pay homage to Lee[5].
  • Kunio can be considered Nekketsu High's Banchō (番長), a Japanese term used to call the leader of a juvenile delinquent gang. This can be noticed due to the fact most of his schoolmates often look up to him (examples include Hiroshi and Sugata), and is always the captain of the Nekketsu High sports team in every respective game. Also, the typical image of a banchō is an uncouth fighter who has a strong sense of honor.
  • The character Yusuke Urameshi from the anime and manga series Yu Yu Hakusho bears a resemblance to him. Yusuke's personality is similar to Kunio's as well.
