The newly appointed manager of the Dolphin Blade team which has fallen on hard times and is heavily in debt. Having lost his previous position at Aihara Electronics as well as his girlfriend who dumped him after realising he was no longer financially attractive, he has to prove his worth as a manager by paying back the team's debt over set intervals or face the sack.

He has no experience whatsoever at managing a sports team and had hitherto little contact with the sport prior to his demotion. On the other hand he is a native of the island where the Dolphin Blade races are widely followed and is determined to learn the ropes quickly in hopes of reclaiming his old position.
