Ryūsaku (りゅうさく ) is a minor character featured in Shin Nekketsu Kōha: Kunio-tachi no Banka. He is a student at Hanazono High School.
Background[]
Ryūsaku is first seen at the amusement park and is recognized by Riki, though he becomes immediately scared after turning around and mistaking Kunio for being Ken. Thinking that he's in trouble for slacking off, he begs for Ken's forgiveness, though realizes that he's not talking to the real Ken after Kunio confusingly asks what he's afraid of. Kunio then asks Ryūsaku what he knows about Ken, to which he informs the protagonists that he only stops by the amusement park on occasion to talk to Shinji and that he was being referred to as Ken. Riki then asks Ryūsaku if he knows about Ken's whereabouts, though he is unsure and only knows that Shinji was last seen by the Ferris wheel. Upon defeating Shinji at the kart tracks, Ryūsaku informs the protagonists that he has taken the highway to the Blue Emperor hideout.
