Malleus Draconia

Malleus Draconia is a third-year student and the head of Diasomnia. He is a descendant of the fairies, and his magic power is among the strongest in the world. He has a distinguished presence at Night Raven College, but his powerful aura causes the other students to keep their distance. Whenever he appears or disappears, firefly-like lights appear. He is considered to be one of the 5 most powerful wizards in the world.

His caretaker when he was still a child was Lilia.
