Itta Akai

He is head of Momohama High. Works in his dad's bike shop, Akai Moters. A strong fighter, and big brother figure for the rest of the gang. Takes huge pride on his work, just like his dad. Foul-mouthed. Really cares about Tomoki and looks after him. Hayato calls him Grease monkey because of his passion for bikes. Itta seems to like Mai.
