Takeshi (たけし) is a member of the "Yokohama Funky", the bōsōzoku gang led by Shinji. He first appears in Nekketsu Kōha Kunio-kun as one of the game's enemies. He is officially named in the Famicom version of the game and is the enemy that rides the bikes during the stage. Noboru is the other member of the Yokohama Funky that fights with his bare hands, while Takeshi uses a lead pipe.
- This character has no relation to Hayami, a character who is also named "Takeshi" and first appears in Downtown Nekketsu Kōshinkyoku: Soreyuke Daiundōkai. Hayami is also a biker.
- Mikoto, a member of the Yokohama Funky that debuts in Nekketsu Kōha Kunio-kun Special, is meant to be an equivalent of Takeshi by replacing him as a fleshed-out character.
