River City: Tokyo Rumble (熱血硬派くにおくんSP 乱闘協奏曲, Nekketsu Kōha Kunio-Kun SP: Rantō Kyōsōkyoku in Japan, which roughly translates to "Hot-Blooded Tough Guy Kunio SP: Brawl Concerto") is a beat 'em up role-playing game in the Kunio-kun franchise released on August 8, 2013 for the Nintendo 3DS in Japan. It was developed by Aplus Co., Ltd. and published by Arc System Works. The localized versions, released on September 27, 2016 and September 29, 2019 in North America and Europe, respectively, where published by Natsume.
The game acts as a direct sequel to Nekketsu Kōha Kunio-kun Special and its prequel, Riki Densetsu. Like both of those games, the story was written by Yoshihisa Kishimoto, the creator of the series. The game uses the same graphical style from Downtown Nekketsu Monogatari, which was also used in Special and Riki Densetsu. Kazuo Sawa, the composer of the original game, also returned to compose the game's music.
This is the fifth game in the Kunio-kun series (since Super Dodge Ball for the Neo Geo) that uses the established Kunio-kun names for most of its characters instead of creating new names, while using the River City brand. Like River City Ransom EX, the graphics in-game are not altered.
A mysterious organization known as the Kanto Lion Alliance is making a move to conquer Tokyo, the prefecture where Kunio of Nekketsu High School resides. Together with his friend and rival Riki, Shinji of Yokohama and Taiyō Academy's Misuzu, Kunio fights to put a stop to the takeover.
Before starting the game, the player must select from two different save files before they can access the game's 5 modes. These five modes are Story (すとーりー乱闘協奏曲, Story Melee Concerto), Rumble (かちぬきかくとう, Winning Fight), Dodgeball (くらぶかつどう, Club Activities), Gallery (ぎゃらりー) and Options.
The player gets to play through the story of Kunio and his allies fighting the Kanto Lion Alliance (Tokyo Lion Alliance in River City: Tokyo Rumble). Gameplay is similar to Nekketsu Kōha Kunio-kun Special, but this time the player can recruit allies, travel by train and have a rematch against previously defeated bosses.
Progress through the game's story mode is linear. The player has access to some of Tokyo's cities, which they can travel to by train once they are accessible. Each city has a number of areas with shops, restaurants and the train station. Each area also has a a hidden Mystery Store like in River City Ransom and Downtown Special: Kunio-kun no Jidaigeki da yo Zen'in Shūgō!. One area of the city will have a boss from the Kanto Lion Alliance, which is fought after a scene. The player must visit each area of Tokyo and defeat the current boss until they finally gain access to the airport, where they travel to Hong Kong for the final battle.
While in peaceful areas of the city, the player will come across various NPCs whom they can interact with by pressing the A button. The player can hit them (either accidentally or on purpose) and depending on the NPC, speaking to them again will trigger a random fight with some enemies or with the NPC.
A battle royal mode similar to the event of the same name in Downtown Nekketsu Kōshinkyoku: Soreyuke Daiundōkai and Nekketsu Kakutō Densetsu. Up to four players can play together through local play or download play using many characters from the series. These characters are unlocked by playing through the Story Mode.
Most characters have a set of fixed Special Moves, with a maximum of two listed for each characters. The player can select six different arenas, set up the time limit (infinite, 1 minute or 3 minutes) set the difficulty level of the CPU and choose which music they want to play. A match will end if all human players are defeated if there are still CPU players standing.
The game's control scheme remains the same, but the number of moves are limited. The player cannot perform any of the moves introduced in Nekketsu Kōha Kunio-kun, such as straddling and running hooks, but it is possible for some characters to grab a stunned enemy if they have a throw special moves.
Up to four players can play a dodgeball game together in the style of the Club Activities Mode in Nekketsu Kōkō Dodgeball Bu (Bean Ball in Super Dodge Ball). The same characters used in Rumble are used in this mode.
All characters have two Super Shots, one performed by running and the other performed by running during a jump. The mode uses the same stages and settings from the Rumble Mode. Similarly to Rumble, a match will be declared over if all human players are defeated while CPU players are still standing.
When a match starts, two balls are left on the ground for the characters to use. If players do not have a ball, they can pick one up from the ground by pressing the A button. The character crouches to dodge a thrown ball with the B button. Pressing A will have characters attempt to catch a thrown ball. When players have the ball, they can throw it by pressing either the A or B buttons.
- Gallery: Includes a Character Database with information on each character once they are met in Story Mode, as well as a Sound Test with music unlocked once its heard during Story Mode.
- Options: Players can increase the volume of the sound effects and music, toggle voice overs ON or OFF, change the game difficulty from Easy, Normal, Hard or Brutal, and change the game's controls. Only which buttons are used for punches, kicks and jumping can be changed. This options can be changed at any time during gameplay.
The game's pause menu is accessed on the bottom screen of the Nintendo 3DS. The map of the game is displayed at all times during gameplay. The player can pause the game by pressing either the Start or Select buttons, and gives players access to a menu with the following items (the L and R buttons are used to switch between them):
- Map: Displays the player's current location along with the location of the next objective.
- Items: Shows the players inventory, including Items (includes scrolls with special moves and consumable food items), Badges that are dropped by enemies and Special items related to jobs and events (key items).
- Status: Displays Kunio's stats and those of his allies, along with what items they are wearing. Pressing the Y button displays their special moves, which can be toggled ON or OFF.
- Jobs: Shows a list of the part-time jobs that are currently in progress. When a job is completed, this option in the menu will be highlighted in green.
- Options: The same settings screen found in the mode select screen. The player is free to change settings as they wish during gameplay, just like River City Ransom, Downtown Special: Kunio-kun no Jidaigeki and River City Ransom EX.
- Save: Has two options. Save allows players to save their game (the game has no auto save feature). The other option returns the player to the Main Menu and Mode Select Screen. The player is warned beforehand to save the game first, lest their progress be lost. Players can save at any time, but cannot save the game during specific events, such as boss battles.
Just like in River City Ransom and its sequels, the player receives money (Japanese yen, Japan's official currency) after defeating enemies. Enemies also drop badges which can be sold for yen at shops. Money is used in these different kind of shops:
- Restaurant: Includes restaurants, curry shops, cafeteria and sushi restaurants. The player can recover Stamina and Willpower for their character an ally here.
- Tech Burger: A fast food joint, the player can take food to go and have it in their inventory.
- Drug Stores: Sells drugs that allows the player and ally to recover together.
- General Store: These stores sell equipment such as shoes, knuckles, belts and undershirts that increase character stats.
- Bookstore: Players can purchase scrolls that teach Special Moves.
- Mysterious Store: Hidden shops that sell expensive equipment and special moves which cannot be found in regular stores.
Some areas have vending machines, like in Shodai Nekketsu Kōha Kunio-kun. The player can interact with them to purchase items.
At an specific point early in the game, the player will be given access to a store which offers Part-time Jobs. These jobs range from defeating a number of specific enemies, fighting specific bosses, and other missions, which reward the player with money, items, and characters to use in Rumble and Dodgeball.
If the player is knocked out and has no remaining Stamina and Willpower, they will lose half of their money. The game will briefly return Kunio to Nekketsu High School, promising revenge, but the game will then return the player back to the same area where they were knocked out. If the player is defeated during a boss battle, they will be returned to Nekketsu High School. The game has an item that removes the loss of money penalty.
Like Shodai Nekketsu Kōha Kunio-kun, characters have levels and gain experience by defeating enemies. The status screen has an experience meter and when full, the character goes up one level. This increases their stats slightly, with the exception of Agility, which can only be increased by consuming items. Some consumable items can grant stat boosts while equipment improves stats as well. Unlike River City Ransom but like in Downtown Special, food items purchased in stores only replenish Stamina and Willpower.
The stats are the same from River City Ransom:
- Punch: How much damage characters make with punch attacks.
- Kick: Determines the strength of kick attacks.
- Weapon: The higher this stat, the more damage a character makes when using weapons.
- Strength: This stat determines the frequency at which a character can break an enemy's guard.
- Agility: Character's moving and running speed.
- Defense: The character's chances to block, performed by pressing an attack button when attacked.
- Stamina: The character's health meter. If it is empty and the character is knocked out and has no Willpower, they will be knocked out and lose half of their money.
- Willpower: If the character's Stamina is depleted and they have some Willpower, the character will get back up from the ground and recover a little Stamina.
Controls & Moves
The game's control scheme is the same from Downtown Nekketsu Monogatari, the A button is used to punch and the B button to kick. The player jumps by pressing the Y button. Once the player acquires an ally, the X button is used to change their AI behavior (become aggressive, assist the player, stay away from the player, or to do whatever they want). The L button switches between 3D and 2D modes, while the R button zooms the screen in.
Pressing the directional pad Left or Right twice allows the character to run in that direction. Unlike Downtown Nekketsu Monogatari, characters will continue running into walls instead of knocking themselves out accidentally. The A button is used to pick up and attack with weapons while the B button is used to throw them. Hitting enemies multiple times will have them stagger, at which point they can be knocked out with an uppercut or high kick by using the A or B button, respectively. Attacks can also be performed in midair, such as the jump kick.
Moves used in Nekketsu Kōha Kunio-kun and Shodai Nekketsu Kōha Kunio-kun can also be done by the player from the start:
- Grab: When an enemy is stunned and groggy from a beat down, the player can hold the directional pad towards them to grab them by the collar. Pressing the A button, the character performs a Shoulder Throw. Pressing the B button will make the character Knee the enemy, which can be done multiple times until the enemy escapes the player's grasp. Holding the directional pad towards the enemy and pressing the B button will make the character switch position behind the opponent, and pressing the button again allows the character to perform a Suplex.
- Straddling: When an enemy is knocked out, the player can sit on top of them, allowing them to punch them with the A button.
- Running Hook: While running, characters can throw a hook that knocks enemies down by pressing the A button.
In the event that the player gets grabbed from behind, pressing the B allows them to defend themselves with a kick. They can break free with the A button.

Natsume released the game in North American and Europe, in the latter region it was only released digitally. River City: Tokyo Rumble is the fight game in the Kunio-kun series that is localized using the names of that franchise, with few alterations. It was first done in Super Dodge Ball for the Neo Geo, then became the norm with Super Dodgeball Brawlers. Like in River City Ransom EX, no alterations are made to the graphics, the game uses the River City name (much like the previous River City Super Sports Challenge and River City Soccer Hooligans) for the purpose of brand recognition.
River City: Tokyo Rumble makes various changes from the Japanese version. Since Riki Densetsu was not released in the West, it is impossible to link its clear save data to Tokyo Rumble, so the western players do not have access to the rewards.
The names of characters, organizations, areas, special moves, among others were changed. All characters introduced in the Nekketsu Kōha Kunio-kun series and the new characters introduced from Nekketsu Kōha Kunio-kun Special keep their names from the Japanese version. Guest characters from the Downtown Nekketsu series, the Nekketsu Kōkō Dodgeball Bu series and other games are given different names. Heilman, Mordov and Njomo are given their names from the NES version of Super Dodge Ball. Sugata, who was previously in River City Ransom EX, keeps his original name along with Saotome, who was in Crash 'n the Boys: Street Challenge.
Kumada and Hayami, who were previously in Crash 'n the Boys: Street Challenge (Kumada was also in River City Ransom EX) are given completely new names. Gōda, Godai, Ryūichi and Ryūji are given their names from River City Ransom. Johnny, who was named Rocky in Crash 'n the Boys: Street Challenge, is named Rocko in Tokyo Rumble (the name given to Nishimura in River City Ransom) while Raphael is given Riki's name from Crash 'n the Boys: Street Challenge. Tobiyama, Toraichi and Toraji are given new names, while Yoritsune keeps his original name.
Hattori Academy, the school that Yoritsune attends, is erroneously named Hasebe High in Tokyo Rumble.
After being defeated in Tokyo Rumble, Ivan will mention Saori, even though she was named Abby in River City Ransom EX.
Most of the above characters previously appeared in Super Dodgeball Brawlers, River City Super Sports Challenge and River City Soccer Hooligans with their original names.
Benijishi (Rouge Lion) is described as a former ballerina in Tokyo Rumble, but in Rantō Kyōsōkyoku, she is instead a former member of a volleyball club. This makes sense, as her signature move is the Fireball Spike.
Codes & Secrets
Riki Densetsu Save Data Link
The Japanese version includes an option that allows players to link their Riki Densetsu clear save data to the game. This rewards players with Riki's Gloves and Riki's Sarashi, which they can equip.
Completing the game for the first time allows the player to save their game. This grants the player the following:
- The player begins the game from the beginning, but they keep their items, stats and special moves.
- Kyoko appears in front of Nekketsu High School, allowing players to switch Kunio with one of their allies. Misako will already allow the player to select Shinji and Misuzu as allies as well.
- The events in Akihabara will be completely different, leading to a fight with Kinjishi.
- Enemies are stronger.
- New part-time jobs appear with new rewards.
Equipping more than one of the items that double the money or experience received will triple their effects, while equipping three of them will quadruple them.
- This game marks Kyoko's second appearance in the Kunio-kun series, 19 years after the release of Shin Nekketsu Kōha: Kunio-tachi no Banka. She also appears as Riki's girlfriend instead of Mami, his girlfriend in the Downtown Nekketsu games.
