* CompleteMonster: Remi Mizuchi. Her sisters, Emi and Ayumi, and their father Gozo may also qualify as they orchestrated the deaths of over 60 of the sisters' classmates in the beginning of the OVA, but Remi brings it up a notch beyond them in the OVA when she [[spoiler: orchestrates their deaths and laughs about it]].
* CrowningMusicOfAwesome: The first opening of the TV series, ''Shiroi hono'', by Yuki Saito.
* LesYay: Between Saki and Junko. Later, there's FoeYay between [[spoiler: Saki and Remi in the manga, and at some point the two sleep together.]]
