Hirata Mihane has a scary face and isn't ladylike at all. In fact, she lets her temper get the better of her and often lets out small bursts of violent behaviour-even though she doesn't mean to. Because of this, the entire school calls her a "Satsujinki" (murderous monster). Even so, she's in love with the kind and popular Touma-kun, who doesn't mind the way she looks and is always nice to her. But... will Touma ever see her as a love interest?
