Hiro

Hiro is the youngest and newest member of Chiba's Gang and he idolizes Chiba and calls him not only "senpai" but "sensei" and has expressed a firm belief that Chiba will become a Sieger. He is very new to fighting and would probably run from a fight if it wouldn't shame him in front of his gangmates. He likes Joji, but dislikes Hayato.

He lacks a proper weapon, wielding only a makeshift quarterstaff made out of a fallen hardwood branch. Chiba most often has him act as a distraction and a ruse to make foes lower their guard.
