Kazuma Ninomiya

About

He is Madoka's fiance (Madoka's father approved the match without her knowledge).
Kazuma is generally a sunny, friendly, and cheerful person. His family became wealthy when he was in middle school. He adores Madoka, even going so far as to search for her, transfer to her school just to be with her, and move into her and Momo's apartment. He also tries to be protective of her, but he is too weak for it.

As a child, Kazuma was homeless and was often bullied because of his destitution and lack of proper hygiene. One day Madoka defended him and was his playmate for a while afterwards (ironically, Madoka doesn't remember any of this).
