King

Once arriving inside the kingdom which Yuki was supposed to live for the rest of his life while being watched and tracked inside, Yuki couldn't help but feel joy as his captors honestly believed that he would stay inside the kingdom and allow himself to not grow in strength while everyone else did. It was single handedly the most foolish thing a person or a group of people could do. Although, they couldn't be blamed as they didn't know of the existence of One nor Zero. Without those two, Yuki would be completely powerless. After all, Yuki was just human. The only thing which made him different from others was the fact that he had overpowered tools which he could use to his heart's content.
