Chaozii Han

Chaozii Han is one of three surviving crew members of Anita's ship after it was attacked by Akuma at sea.

Appearance
Chaozii is a short man with thick, unruly, hair fixed on the back of his head. His bed-hair tends to stick out in every direction.

Personality
Chaozii is a very soulful man, full of doubts. He is very loyal, and when he gets attached to a certain group of people, he will not let go of them even if it would equal his death. He is not one to bottle his emotions and voices all of them out easily, but tends to cry a lot.

Chaozii seems to hold a particular grudge against Allen ever since Allen suggested saving an unconscious Tyki Mikk from the dying Ark; Chaozii, seeing the Millennium and all his affiliates as his enemies, believes Allen has betrayed them, and still couldn't forgive Allen after the Ark's been restored. After Allen escaped from confinement, Chaozii, under the believe that Allen has defected to the Noah Family and killed an inspector, severed all bonds with Allen and saw him as an enemy and that he (Chaozii) will fight to kill the next time they meet.

History
Chaozii was a 3rd class sailor on the ship.

Edo and Asian Branch Arc
Chaozii is first introduced as he tries to lie in order to stay with killed crew of Anita's ship during the Akuma raid on the Japan sea. Anita was able to convince him to leave with the Exorcists, though he still displayed some reluctance.

Noah's Ark Arc
Chaozii was seen reacting with an Innocence sent into Noah's Ark by Froi Tiedoll. The Innocence came to Chaozii when he had to save himself and Lenalee Lee from being crushed by falling debris during the attack from the transformed Tyki Mykk. Being extremely loyal to Anita and her crew, he developed an extreme hatred of all Noah and Akuma after their deaths, going so far as to accuse Allen of being evil for sparing the life of Tyki Mykk.

Chaozii is willing to become an Exorcist and is to be a disciple of Froi Tiedoll.

Invasion of the Black Order Arc
Chaozii tries to tag along with Kanda in order to fight alongside him against Level 4 akuma. However, he stays back to assists the others to escape the area in which the Level 4 was rampaging.

Third Exorcists Arc
Chaozii goes on a mission to China along with Lavi and Bookman and several finders. At the same time that the other teams across the world are attacked, Chaozii and his team are ambushed by Fiidora. The exact details of this battle are unknown, but both Lavi and Chaozii are infected by the Fiidora's parasite. After Fiidora abducts Lavi and Bookman, Chaozii is discovered by his finder comrades and seems to be incapacitated by pain. He has since been sent to the Black Order's hospital wing, but no progress has been made in curing him of Fiidora's parasite.

Seeds Of Destruction Arc
Chaozii eventually heals from the unknown symptoms brought to him with Fiidora's parasites. Unbeknownst to him, though, he still carries some of the parasites within his body, which the Noah Family plan on using to spy on the Order to keep an eye out for Apocryphos. After getting better, he's now an active Exorcist who deals with missions just like any other member of the Black Order.

Even three months after incident, Chaozii still can't believe that others have such a hard time coping with Allen's disappearance. Furthermore Han holds a grudge toward Allen, who officially, is responsible for killing Howard Link. The man hopes to set the score with the fugitive next time they meet.

Innocence
Arm of Baptism (洗礼ノ腕輪, Senrei no udewa): Chaozii's Innocence is a Equipment-type that appears as a pair of linked bracelets on his left wrist, granting him superhuman strength. When invoked, it takes the form of a pair of gloves with circular buttons on each knuckle and cloth-like extentions on the wrists.

Trivia
