Nekketsu Kouha Kunio-kun: Bangai Rantou-hen

Players assume the role of Kunio, who must avenge the beating of his friend Hiroshi at the hands of Yūji Munakata, the only son of the chairman of Munakata Industries. Yūji has also been terrorizing Hanazono High School, so Riki joins Kunio as well, provided that another player has another copy of the game and the Game Link Cable. Though the game was released after Downtown Nekketsu Monogatari and uses similar graphics, they game doesn't give the player an option to choose between Kunio or Riki (the first player always controls Kunio and he is the only playable character in a single player game, only the second player can use Riki, though both characters play the same).

Nekketsu Kouha Kunio-kun: Bangai Rantou-hen is the first game in the Kunio-kun series released by Technōs Japan for the Game Boy. It is a sequel to Nekketsu Kouha Kunio-kun, but uses the graphical style of Downtown Nekketsu Monogatari, which was previously released on the Famicom. This is the second game in the Kunio-kun series that has Kunio and Riki joining forces against a common threat, which would become a standard in later games.
