Shinku Nikaidou

The "Magician" whom only Yuma can see. She is very much the serious, intellectual type, but at the same time a passionately caring individual. She has an aversion to "ecchi" things as well as an endless hunger for pancakes. She continually reminds Yuma to write in his diary in order to retain his memories from day to day, and whenever he uses his power, she reminds him of its cost, desperately wanting him to care for himself as well as those he heals.
