The mascot of the academy, is a strange floating creature that encounters Itsuki and Mahiru outside the first Labyrinth they escape from. Mana finds them in the forest and introduces itself, and is rather annoyed by being referred as an 'otaku figurine' and 'toy' from Mahiru. Mana is rather mischievous, having enough misbehaviour to think lesser of Itsuki's name when he introduces himself. She's also able to sense the virginity of the twelve star maidens, such as when Mahiru first transported to Granvania and met her.
