Shinji first debuted in the original Nekketsu Kōha Kunio-kun as the second boss of round 2 along with his bōsōzoku gang.
Shinji makes an appearance in the game as one of the main antagonists and a boss. Shinji takes over an amusement park along with some other gang members.
He is one of the unlockable players in the game. According to his in-game bio, he was Riki's Soccer Club Senior in middle school. After his stint as a badass, he changed his ways and dropped out of high school. He currently works at a factory in his hometown.
- Unlike veteran antagonists Misuzu and Sabu, he is the only character who has had very few appearances in the entire Kunio-kun games franchise, only appearing in Nekketsu Kōha Kunio-kun, Shin Nekketsu Kōha: Kunio-tachi no Banka, and Super Dodge Ball for the Neo Geo.
- Bōsōzoku (暴走族, literally "running-out-of-control (as of a vehicle) tribe") is a Japanese youth subculture associated with customized motorcycles, mostly illegal. It's also a term used to refer to a biker gang, which is the case for Shinji's gang.
