Ranma 1/2: Byakuran Aika — About this game
Byakuran Aika centres on a new Ranma story involving Arisa Nanjo and the disappearance of Ranma's friends. The player follows scenes and chooses what Ranma should do or say, with animated sequences carrying the consequences forward. Encounters also use a rock-paper-scissors-style battle system rather than the direct fighting controls of the series' tournament games. The emphasis is on following the characters and making choices within a voiced Japanese story.
