Being a magician Kuroha has the power to destroy any inanimate object, as well as transferring power when in direct contact with organic beings. Her power is so strong that while being in the lab, she had to undergo multiple extensive tests. As a result, Kuroha has almost completely forgotten her childhood memories, with only a few bits of emotion lingering.

Although usually gentle and caring, she can be short-tempered when embarrassed. She easily gets jealous when Murakami is "too close" to other girls (especially when Kazumi is seducing Murakami) and she would use her magic to destroy things around unconsciously. She is very puzzled by this reaction.
