Daybit no Chichi

He is Daybit Sem Void’s father whose name has been removed from the world. He disappeared one day in July 2004, after an experiment in which an Angelic Artifact was exposed for 0.2 seconds. His name was erased not just from the Department of Lore's records, but from everyone's mind, with his at the time 10-year-old son being the only survivor.
