While Toriyama was serializing "Dragon Ball" weekly, Torishima recruited him to work as character designer for the 1986 role-playing video game "Dragon Quest". The artist admitted he was pulled into it without even knowing what an RPG was and that it made his already busy schedule even more hectic, but he was happy to have been a part after enjoying the finished game. Toriyama has continued to work on every installment in the "Dragon Quest" series. He has also served as the character designer for the Super Famicom RPG "Chrono Trigger" and for the fighting games "Tobal No. 1" and "Tobal 2" for the PlayStation.
