Hayate Yagami

Intelligent Device(s): Buch der Nachthimmel/Book of Darkness (Storage/Tome), Schwertkreuz (Rod), Reinforce II (Unison Device)

Hayate, a sweet wheelchair-bound orphan, is under the care of the Wolkenritter, though they keep their battles from her; she knows that the completion of the Book of Darkness will grant her vast power, but does not want it at the expense of the lives of others. However, the Book of Darkness is feeding off her own life force, causing her paralysis, and will eventually kill her if it is not completed... Hayate and Suzuka become fast friends after Suzuka helps her around the library, which may cause trouble if their respective friends learn that they have been fighting each other.
