Origin

Chien Khan was a Japanese gangster who was constantly accompanied by his pet pitbull. He joined the Golden Triangle Gang, but was double crossed by them and he and his dog were sealed in an airtight shipping crate by the gang and left to suffocate to death. Chien had a dark secret though, he was adept in black magic and used this ability to summon, and make a deal with the Oni named Noi'Tai'Dar, Chien did not ask for much, just his survival and the tools to get revenge in exchange for his soul and servitude to Noi. Noi'Tai'Dar used his demonic power to join the bodies of Chien and his dog into a human/dog chimera, and Chien was granted what he asked for, but not in the way he expected.
