Birthday: 12th July

He is a rather weird hyperactive fantail pigeon and captain of the track team.

He can run on foot faster than Hiyoko, despite being a pigeon and half her size, and is often heard zooming around school.

Because of his obsession with pudding, Okosan dedicates whatever time he doesn't spend running about to his search for The Ultimate Pudding of seven colours.

Okosan speaks in coos, the meaning of which are then translated in brackets.
