Shodai Nekketsu Kōha Kunio-kun is a beat-'em-up game for the Super Famicom and the first Kunio-Kun game for the console. The story is set around the end of Kunio's sophomore year, as he and his friends take a trip to visit Osaka. Like River City Ransom, Shodai Nekketsu Kōha Kunio-kun is an open world role-playing game which focuses on the elements of stats, items and leveling up. Kunio's former rival, Riki Samejima makes an appearance to serve as the second player of the game and ally of Kunio. Most of the game is set around distinctively exploring Osaka and to progress through the game's story overall.
