In the manga, Hayato was a terrorist who lead all his operations from a high school that he took over. The first thing we see him do is plan to kill the cabinet minister by rigging a bridge to only support one car so that when both his armored car and his escort car were on a bridge the minister would freak out run out of his car and Hayato would proceed to shoot him.(seriously, just blow the bridge up) However, his goons don't like to listen and speak over him. This reminds Hayato that he constantly has bugles on his fingers and can rip people's face off and poke ears and eyes out.
