Allen is the sort of person who strongly believes in what he fights for, even when it seems the whole world is against him. Despite his youth and tragic past, Allen is remarkably mature and selfless. Much of this, in my opinion, is thanks to his father, Mana, evidenced by the strong attachment Allen had for him. Still, Allen is young, and when provoked enough, he has a tendency to attack with far too little care for his own safety. Personality-wise, he’s very honest about his feelings and he will show exactly what he feels, and say exactly what’s on his mind. Allen eventually met Cross Marian, a general of the Black Order, who explained to Allen the way of the Akuma and the trapped souls within them: Once a soul becomes trapped inside an Akuma, they are trapped forever; and that the only way to save one is to exorcise them from their Akuma vessel. Allen subsequently became Cross' disciple and spent the next three years with him before being sent to the Black Order to become an official exorcist.Allen’s left eye is not powered by Innocence. In fact, it’s referred to as a curse. When activated, it turns red and the pentacle on his forehead glows. The eye can differentiate between humans and AKUMA, but more than that, it can see the human souls trapped inside the AKUMA.

An 18 year old Exorcist from Japan. He can recover much faster than ordinary humans due to a mysterious tattoo above his heart ( possibly the word 'Om' ). It is related to a lotus flower, sealed in an hourglass, that is connected to Kanda's life. It is said that when it wilts, he will die. His purpose in life is to find a person that he refers to as "that someone"; which will be hard but until then, he will never allow himself to die. So far, the lotus flower has lost three petals, but is otherwise still robust - it has 13 petals in total. Kanda seems to be able to withstand the blood of Akuma, most likely due to the tattoo above his heart. The hourglass and flower are said to be his only personal possessions. He was grudgingly partnered with Allen in Allen's first mission.
He has long black hair, which the mangaka noted that he uses soap to wash. In the anime, Lavi also once braided Kanda's hair, causing himself to nearly get sliced by Mugen. He also commented that Kanda is a "pretty-type character", and Allen even called him "Feminine face" etc. However, he has a harsh tongue, foul mouth and a cold manner, and tends to say "Che" a lot. His master, General Tiedoll, calls him "an anti-social humbug." Yu is Kanda's given name, but he dislikes being called that. He masks his emotions and often claims, "It's none of my business." His favorite foods are soba noodles and tempura ( especially pumpkin, shishitou[a kind of small sweet green pepper], and lotus root ). Kanda dislikes so many things to the point that "there are too many to write down". But it is a known fact that he hates people with naive personalities ( Allen ), people who can't keep their mouths shut ( General Tiedoll ), people calling him by his given name ( Lavi ), and "sweet things" ( As in food ). His anti-Akuma weapon is a black katana, "Mugen" ( 六幻 ), which turns silver when activated. "Mugen" ( in this case ) means "six illusions". He runs his index and middle finger through the back of the blade to activate it. As the sword is called "Mugen" ( 六幻 ) and " 六 " means six, it is speculated that there will be three more attacks. It could also be that the 6 in the name is added to make a phonetic misinterpretation of the name possible : Mugen written as " 無限 " means " infinity ".

A cheerful red-haired Exorcist of mixed race, who aims to become a Bookman and is working along the Black Order just to be close to the events that must be seen. To help him, he developed an incredible memory: he is able to memorize every single aspect of something he saw, but he commented ( in chapter 101 ) that he could identify "the key" ( the key which Tyki Mikk gave ) faster if he were to use both his eyes when sieving out the real "key" from the fake. He is 18 years old, and normally uses his left eye while the right eye is covered by an eye-patch. His anti-Akuma weapon is a size-shifting hammer, which he calls Ōzuchi Kozuchi ( 大槌小槌, lit. "big hammer small hammer" ) or Nyoibo. It can grow ( 満, man ) or extend ( 伸, shin ). The weight increases with its size, but since Lavi is the conformer, the weight does not effect him; However, it does to everyone else. His hammer can also summon several "judgments" with kanji possibly representing the classical elements that can be used individually or combined. However, between some of the seals are question marks. This probably means that Lavi has some seals that he has yet to learn from his Innocence. It was revealed that his name, Lavi, is just an alias ( his 49th, to be exact ). He had cast aside his old name and background to show his commitment to being a Bookman. It was also revealed that Lavi was once cold and indifferent to others, for a Bookman only lives to view and record history and that humans are nothing more than 'ink' on a page. However, over time Lavi's personality changed and he began to truly care about others, slowly casting aside his identity as a Bookman. There are many different translations of his name, such as Ravi, Rabi, Labi. But is is found in the D.gray-man Omake from episode 61 that the correct spelling is Lavi.

Komui's younger sister, and assistant Head Officer. She is Chinese, and 16 years old. Her parents were killed by an Akuma when she was very young. Because she is an Accommodator, the Black Order took her away from her only remaining family member ( Komui ) to Headquarters against her will. For three years she was never allowed to leave the place, which felt like a prison to her. Because she attempted suicide, she had to be restrained and tied to her bed. However, once Komui joined the Black Order three years later, Lenalee became more at ease in the Headquarters. In the later chapters, she states that she feels like she imprisoned Komui at the Headquarters ( that he had thrown everything out for her sake ). She once told Allen that her "world" consists of her friends and family; if something terrible were to ever happened to one of them , it is the same as part of her world being destroyed. As the storyline progresses, it is hinted that she has feelings for Allen. She is an Exorcist whose anti-Akuma weapon was a pair of boots, or "Dark Boots" ( 黒い靴 ). When invoked, it greatly increases one's speed and strength in the legs. She has a strong sense of friendship, which sometimes causes her emotional pain ( or causes her to fight with her comrades ). It is shown that even though she has lost the use of her Anti-Akuma weapon, she hasn't lost her will to fight for other's sake.Her name is spelled 'Linali Lee' in VIZ Media's translation ( In the midst of volume three, however, it changed to Lenalee, then occasionally switched back to Linali ). Another translation of the name is Rinali, as in the Japanese language R and L are the same consonant. It was said in Volume 3 that Lenalee resembled someone to Hoshino Katsura. After she told her editor, he laughed so hard that it made her swear not to tell it to anybody else ever again.

An old man who records the hidden history of the world. He comes from the Bookman clan and doesn't have a name. He simply introduced himself as "Bookman" during his first meeting with Allen. Lavi accompanied him when he appeared. He refers to Allen as "The Destroyer of Time", as he believes that Allen is the only one who can defeat the Earl of Millennium. Bookman also mentions that a "Bookman" does not put himself in the frontline and he just happens to be on the same side as the Black Order.His anti-Akuma weapon is called Heaven Compass (天針), which is a set of acupuncture needles. In addition to Bookman's own skill in healing people through acupuncture.

A woman whose clock caused time to rewind in her town, which started when she was able to connect to the Innocence within the clock. She is German, and twenty-five years old. She often feels inferior and useless, which caused her to be fired from all one hundred jobs she tried to work in. This contributes to her chronic depression. With the help of Allen and Lenalee, she became determined to be a useful Exorcist.
Her weapon is a disk called "Time Record" (刻盤), located on her right arm. When activated, it appears from her right arm and "slides" to her wrist. The name of the character is inspired by the actress Miranda Otto.

Full name Arystar Krory III, he is a Romanian with split personalities: a soft, kind, and overly-emotional "normal" side, and an aggressive, cocky, "battle-mode" side. The dominant personality is easily distinguished by his facial appearance. When 'normal', his long strand of white hair hangs down in his face. In addition, his appearance is kind and somewhat down-cast, and his voice is soft and low. When he enters his "battle-mode", the white strand of hair on stands up. Additionally, the whites of his eyes turn black and veins protrude from his face, making him look like a monster. He also talks in a loud and aggressive voice when battling. Instead of using the name of the infamous Aleister Crowley, Katsura Hoshino used a name that sounds similar to it.

One of the Exorcists in General Winters Sokaro's team who was killed by Tyki Mikk. In volume 5, Suman had a nightmare about seeing Kazana and his corpses. His anti-Akuma weapon was a cross-bow. In the anime though it is shown his weapon was capable of shooting out bolts of lightning towards the enemy.

A cheerful Exorcist from Bodrum, and ( in the anime ) a fan of Football ( soccer ), who ran away from his family's souvenir shop in search of adventure. He was a disciple of Tiedoll and was on his rescue team along with Yuu Kanda and Noise Marie; despite his love of playing pranks on the other members of the order ( for example, using his Innocence to crack Tiedoll's glasses ), he was described by Theodore as "a good kid." His Exorcist outfit features a pointed cowl with a bell on the end, similar to the coxcomb of a medieval jester; the bell ( originally from the door of his shop ) becomes his anti-Akuma weapon, a projectile called the Charity Bell ( 隣人ノ鐘 ). This weapon, wielded much like a Football, can break through multiple Akuma and causes any it hits to resonate ( like larger bells ) until they explode. While on his mission to find General Tiedoll, he encountered Tyki Mikk and was found the next morning hung in an upside-down cross fashion from a streetlamp, missing an internal organ and the Charity Bell. In the anime, he said he had not wasted his life, just before Tyki killed him. After learning about Daisya's death, Tiedoll mourns him, and he wishes Daisya to rest in peace.

One of the Exorcists in General Klaud Nine's team, now deceased. Not much is known about her. She was never seen.

Hevlaska, also called Guardian of the Innocence, is an Exorcist who has a major role in Black Order, being a part of the Organization since its very beginning. Hevlaska has its body completely enveloped by its Innocence that seems to be indefinitely active. Its abilities consist of merging some tentacles of its body into other Exorcists' bodies and Innocences. This way, it can know their nature - even if an Innocence is the Heart - abilities, synchronization percentage and hidden potential. Its personality is calm and gentle, almost maternal ( which can suggest Hevlaska is actually a woman, which is later revealed as true when Komui states Hevlaska's gender to Allen. In episode 6 of the anime, Lenalee says that Hevlaska is female ). The name "Hebraska" is used in VIZ media's English translations for volumes one and two. Allusions are made that the Innocence it carries is actually the Innocence Cube. When Allen's Innocence achieved 'critical point', Hevlaska could feel his power, as all the Innocence cubes inside her body were resonating ( painfully at that ). It was Hevlaska that stated that a new 'General' was being born. In the latest manga, Hevlaska is seen telling Komui to take the Innocence to the Asian Branch as she wishes to sacrifice herself to protect everyone else from the immensely powerful Level 4 Akuma. However, Malcom C. Rouvelier has other ideas.

A member of Winter Sokaro's team. He, along with Chakar Rabon, was killed by Tyki Mikk. In the anime, it was shown that his Anti-Akuma Weapon was a sword which once activated grew up to several times its normal size, although the additional weight does not appear to affect him, much like Lavi's Innocence.

One of the Exorcists from Tiedoll's group. Noise Marie seems to be a tough, silent man. His innocence, "Noel Organon" ( 聖人ノ詩篇 ), gives him an incredibly strong hearing, allowing Marie
