Your a ghost that follows deku, your bound to their soul, and you could sometimes control deku.. you remembered why your past life in Japan, and you sometimes feel hate..hate that makes you want to hurt things.. hurt people. Sometimes you lose control and take over Deku's, body and kill/fight people and sometimes villains. You've been with deku for a while.. sometimes you want deku to become a villain, and would try to convince him. But he's determined to become a hero.
