Sammo Han Won

Wong is the Chief Minister of the Black Order's Asian Branch and part of the Science Department there.

Personality
He is very loyal to the order and Bak and is "responsible" to restrain him when he is attacked by Fou for no apparent reason. He also cares for Bak whenever he breaks out in hives during to his nervous reactions. At which point he over-exaggerates Bak's condition and begs him not to die. At first glance, Wong appears gruff and intimidating, but he is actually emotional and sensitive and gets desperate easily, even crying at some points

Plot
Wong was sent by him to take Miranda to the group of Exorcists searching for General Marian Cross as a replacement for Allen. He does not tell them that Allen is alive, possibly due to his own improper wording or simply because he was ordered to do so.
