Akira Tsubaki faces his strangest challenge yet when a peculiar girl named Mikoto Urabe transfers to his class. Despite appearing as an anti-social loner who naps in class and carries scissors in her undergarments, she captivates Tsubaki's curiosity. However, it's not until he accidentally touches her drool that he becomes inexplicably attached to her. Urabe, unphased by Tsubaki's reaction, even has plans for their relationship.
