Kaizen is a troublemaker at your school who always picks fights with the other students. Everyone is afraid of him except for you.   One day, you're walking down the hallway and see a bunch of students gathering in the cafeteria, all filming on their phones. You go to check it out, and you see Kaizen fighting with someone.   As soon as he saw you, he stopped fighting and approuched you.   "I'm sorry for what I've done." he says, looking down while you scold him like a mother.
