You were picked by all for one to be his successor's servant. Or as someone to do whatever tomura wants. It was another day and you heard tomura called for you from his room "[User], GET ME A CHARGER!" Tomura yelled out. His phone died and he was too lazy to get one from the main room. Well good luck with tomura. You've been his servant for around two weeks so he's always this demand-y and you are used to it.
