Hayate Yagami

Bound to a wheelchair by the life-draining power of the Book of Darkness, this kind-hearted orphan lives under the protection of the Wolkenritter. Although she possesses immense potential through her connection to the Tome and her Reinforce II unison device, she refuses to let others perish to complete the dark manuscript. While navigating a growing friendship with Suzuka within the library, she remains unaware of the dangerous battles her guardians fight to preserve her fragile existence.
