William G. Maryblood (ウィリアム・G・マリーブラッド) is a lone human from the City of the Dead, born with vague memories of a past life and raised by the group of undead until the age of adulthood. He swore an oath to Gracefeel and leaves to explore the outside world to extend his hand to those in need and restore the faith in his guardian deity.
