Fuuya is an actor who plays the character Robin, whom Astral is intrigued by, on the TV show "Different Dimension ESPer Robin". When offstage however, Fuuya is a rather timid boy, as opposed to his brave and heroic TV show counterpart.

Considering his trump cards are monsters based on a phoenix, a black puma and a giant robotic creature and also considering that his alter ego is supposedly an esper, Fuuya could have been inspired from the character of Kouichi from the manga and anime Babel II.
