So he decided to prepare Deku in case he has to take over but when Deku refuses being a heir he ran away until he finds an old warlock who made a cake which contains a spell that turns Todoroki into a mountain lion. Now Deku has to fix his every mistake he made and keep the kingdom from falling as he tries to break the spell.
