Bak Chang

Bak Chang is a fictional character and member of the fictional religious organization known as the Black Order, in the anime and manga series D.Gray-man, by Katsura Hoshino.

Appearance
Bak Chang is a slender man with short messy blonde hair which falls over his face. As Head of the Asia Branch, he wears a white coat which in his case is customised into a tight-fitting waist length jacket with rose cross on the left side. He usually wears Italian style boots and also a beret with a tassel and spirit stone on the top. Bak has tattoos on his both arms

Personality
Like Komui Lee, he is a man aware of his duties and dark legacies surrounding the Order. Even not being a Conformer, he is able to preform some spells, mostly to control the structure of the headquarters thanks to the seal created by his great-grandfather and the blood of Chang's clan. Bak is a responsible leader. It's said his intellect is a triumph of the Asia Branch. Due the noble-like upbringing Bak refers to himself as "Ore-sama" (which can be translated as: "my honorable self", "divine me", or "the great me") when he is angry (more specifically, angry at For), but otherwise he usually calls himself "boku" (a less formal way for noble males to refer of themselves) When he experience strong emotional disturbance, he breaks into hives - all of those incidents are treated as life threatening by Wong. Bak has tendency to cry without his own knowing.

History
Bak is a son of Twi Chang and Edgar Chang Maltin. He was raised like a prince and had very strict education. His mother believed that it will provide him position of a supervisor so he could change the negative aspects of the Black order. Bak Chan is the leader of the Black Order's Asia Branch, a post occupied also by his great-grandfather, maternal grandfather and mother, Twi Chan (and perhaps the other generations of his family). Before becoming the Asia Branch Chief, he once served as a Section Chief in the Northern Sector of the Asia Branch. He and Komui seem to be good friend as Komui address him as Bak-Chan (Dear Bak). Due to Komui's sister complex, Bak doesn't let him (or anyone else) know about his secret stalker-ish crush on Lenalee, and this fact was used by Allen Walker to threaten him so he would open the door where Fou was fighting with an Level 3 Akuma.

Edo arc
When Allen was defeated by Tyki Mikk and had his Innocence destroyed, Bak took the young exorcist in, training him to regain his Innocence, untilThread, a Level 3 Akuma, attacked the Asia Branch. After Allen's molecular bonds were weakened by Thread, Bak refused to let him re-enter battle - not even when Allen threatened to inform Komui about his collection of Lenalee's pictures. Bak eventually opened the door, allowing Allen to enter upon the latter's insistence and determination. After seeing Fou is seriously injured, he went to her and trying to protect her.

Noah 's Ark arc
Asian Branch chief is later seen as he explores newly captured Ark(much to dismay of the rest of the Asian Branch scientists ) with his loyal servant Wong. During exploration Bak meets Reever Wenhamm and Johnny Gill Later that day Bak is summoned by Malcolm C. Leverier to attend the meeting involving cases of Cross Marian and Allen Walker

Being disgusted by Leverier’s accusations toward Allen and Rene Epstain approval of man’s point of view, he rises a complain but is quickly silenced by Komui Lee

Headquarters Invasion Arc
All Branch chiefs stays within headquarters for a couple of days Bak is heaving a breakfast among them. To Bak’s disbelief the whole Black Order is full of gossips of Allen’s possible treachery.

Later that day he tries to convince Johnny and the rest of the science division to let him help with research of “the egg”. During the conversation Johnny is stabbed by Lulu Bell disguised as Oceanian Branch chef. Within seconds all the entrances to the lab are sealed with swarms of akumas attacking.

Bak along with Renee and Johnny managed to avoid capture and instantly start to work on the talisman to entrap the akumas – he contacts with Reever(who do too work on similar device) by Johnny’s headphones. He barely bears the horrid massacre made by the skulls on wounded scientists

As Allen and Bookman enters the lab via the gate and the fight continues the talisman is complete with which the several akumas are entrapped.

Bak is seriously injured during the evolution of akuma into the Level 4, he is seen with the rest of survivors(with Wong wailing over his health.) after meeting Komui he praises his science department bravery.

Komivitan D
After decision to move headquarters he assists with the moving and makes a vaccine for Komuvitan D when it was needed.

Trivia

 * Fou tells Allen that a person once was lost in the Asian Branch for a week and nearly starved. Bak is undoubtedly this person, as he jumps and quietly scoffs at the comment.
 * Bak is sometimes portrayed in a frog costume
 * After the accident with Komuvitan D, Bak was the one who made a vaccine and cured everyone.
 * Bak had long hair - just as Komui Lee - when he was younger
 * For refers to him as Baka-Bak (Idiot-Bak)
 * Though chinese, Bak's last name - Chang - sounds the same as a Japanese honorific - -chan - used for name diminution. Because of this, Komui sometimes teases Bak by calling him either Bak-chan or Bak Chang-chan instead of Bak Chang
