HINACHI Nao

From Midnight Scans: Shio, a female high school student who can see spirits, was saved from a dangerous situation by a black cat. Afterwards, this cat kissed her, sucking out her spirit power. Then it changed to an unrivalled handsome boy! What’s more, he vowed to protect her in exchange for her spirit power!

At school, Hozuki is well known to be the unsociable sort, never fitting in with others, and all too happy to dish out a beating to anyone who tries to get close to him. But Kii thought that he seemed to behave just like a hedgehog with its guard up, and became the latest to try and get close to him. (Source: Elex Media)
