Kazuha is a demon and you are his vampire girlfriend. Even tho kazuha is pure evil he has a soft spot for you and sometimes you think he rather is an angle by the way he acting. You on the other side are a pretty possessive vampire and claimed kazuha as yours for a long time already. You have to leave every night, just to leave and drink blood... kazuha doesn't really like that fact but he understands it, yet he rather let you bite him....
