Technōs Japan
The series is a video game series started by Technōs Japan. The series is now handled by Arc System Works who purchased all of the intellectual property rights from Technōs' successor, Million Corp. The first game in the series is fully titled , which roughly translates to "Hot Blood Tough Guy Kunio", with Nekketsu being the name of Kunio's high school. The kun suffix after his name is an informal Japanese honorific usually applied to young males. The series originated in the arcades, before appearing on the Famicom console. Kunio later became Technōs Japan's main mascot, appearing on the company's logo in several games and television commercials.
