Hideo

How Hideo joined the Tourney
Hideo first appears in Rival Schools, introduced as a Japanese language teacher who is sent along with Kyoko Minazuki to recruit students for Justice High School. The game's story has Hideo eventually brainwashed by the school's principal and forced to bring in students to the school, but is snapped out of the brainwashing by students from Taiyo High School. Hideo's story has him show concern for Kyoko and in his ending, he proposes to her.

In Project Justice, he and Kyoko, along with fellow teacher Hayato, investigate who is responsible for the new attacks on the school and eventually discover that a student at Justice, Kurow, is responsible. In story mode, Hideo is playable in the Justice High School, with the ending showing him hospitalized from the investigation, due to him rescuing a presumably dead Hyo from the burning Justice High building.

Upon learning that Hyo was possessed by his father Mugen's soul, Hideo had hoped to find a way to cure him. Hideo went to Southtown's Pao Pao Cafe and met with the bartender, Richard Meyer to find a relic that may cure Hyo.
