Chang, Bak

バク・チャン

Bak Chang is a 29-year-old Chinese descendant of a German wizard and one of the founders of the Black Order. He also serves as the leader of the Black Order's Asia Branch, a position previously held by his great-grandfather.
Like Komui, he is fully conscious of his duties and strictly follows God's will. Due to his great-grandfather's seal and his bloodline, he can use spells that control building structures. As the branch director, he is a cold and highly responsible leader, though he is actually caring toward others. Nine years ago, the Chang and Epstein families were forced to participate in the Synthetic Disciple Project, which created Exorcists known as Second Exorcists. Since Kanda was created through this project, Bak feels deep remorse and worries that the creation of Third Exorcists might offend him. He also maintains a close relationship with Fo.
It is most probable that he is related to Edgar Chang, the former assistant head of the Asia Branch, and Twi Chang, the former head of the Asia Branch.
In recent chapters 189-193 detailing Kanda's past, it is mentioned that Edgar had a child with Twi, making him a father. Edgar may have acted as a father figure to both Alma and Kanda. Due to various unfortunate circumstances, he is later killed by Alma. Twi's status is unknown, but he has most likely been killed by Alma as well.
When Bak Chang was 20 years old, he and Noise Marie met Kanda, albeit briefly. He has a stalker-like infatuation with Lenalee, evidenced by a folder of photos he carries with him. When questioned (and later blackmailed) about it by Allen, he broke out in hives.
