Bak Chang is a 29-year-old Chinese descendant of a German wizard who was one of the founders of the Black Order. He is also the leader of the Black Order's Asia Branch, a post also occupied by his great-grandfather. Like Komui, he is a man completely aware of his duties and will follow God's will strictly. He is able to use spells that control the structure of the building because of his great-grandfather's seal and his bloodline. Acting as the director of the branch, he is a cold and very responsible leader; however, he is actually very caring toward others.
