Paris's vagabond/Vigilante

an aspiring engineer/fighter gets transferred to a highschool in Paris and makes friends with its residents. though as time passes on this peaceful era wouldn't last and as the town turns chaotic he couldn't stand there and let people get hurt. "DOING SOMETHING ILLOGICAL IS BETTER THAN GIVING UP AND NOT TRYING!!!!!" this is the code our hero follows and he sticks by it no matter what.
