Kanda Yuu is a main protagonist and a member of the fictional religious organization known as the Black Order in the anime and manga series D.Gray-man by Katsura Hoshino.
Kanda is a young and handsome Japanese man often found in any mood that isn't positive. His long black hair (dark blue in the anime) is noted to be washed with soap. Lavi comments that Kanda has a "pretty-type character," and Allen occasionally calls him "feminine face." He also has dark eyes according to the head of the Asian branch (9 years ago), but his eyes are blue in the manga. Kanda seems to be quite proud of his hair.
Personality
Kanda comes across as cold, stoic, and arrogant, even towards his fellow exorcists. In battle, he will do anything to win, sometimes at the risk of his teammates. He once sarcastically joked about leaving them to die. It's his opinion that exorcists are not saviors.
Yuu or Yuu is Kanda's given name, though he dislikes being called by it or even introducing himself as such. He calls Allen "bean sprout" (モヤシ, moyashi, English Dub: "Short Stack"). Though Kanda knows Lavi, he doesn't hesitate to threaten him if Lavi calls Kanda by his given name. However, it's clear that Kanda does care for his fellow Exorcists and the Finders (whom he claims not to care about).
He tends to mask his emotions and often claims, "It's none of my business." Despite his intentions, he and Allen are often at each other's throats and rarely see eye-to-eye on anything.
Kanda's personality hasn't changed much since he was young. At age 9, he was moody and easily annoyed, especially towards Alma Karma, another "second exorcist." Their final conflict seems to have hardened him further, as no display of frivolity has been witnessed since then.
Kanda's favorite foods are soba noodles and tempura (especially pumpkin, shishitou, and lotus root). He dislikes many things, including people with naive personalities, those who don't keep their promises, cursed people, people who can't keep their mouths shut, people who call him by his given name, and "sweet things."
History
Kanda was originally an Innocence accommodator and exorcist of the Black Order but was killed by an Akuma. There was also a woman in his life whom he loved.
Kanda is "reborn" as a second-generation exorcist created by the Order 9 years before the current events of the story through the efforts of the Epstein and Chang families. His body was modified to heal incredibly quickly to sustain synchronization tests. He regularly underwent cruel and painful procedures to force synchronization with his Innocence, literally tearing him apart in the process. Due to his second exorcist strength and ability to regenerate, the procedure was repeated even after he had "died" several times. Initially hostile towards Alma Karma, another child of the second exorcist program, they eventually became close friends due to their shared experiences.
Yu begins seeing an illusion of a woman Alma initially assumes is Fou, the guardian deity of the Asia branch. He also starts dreaming of her and his death at the hands of an Akuma. The Order realizes this and decides to terminate Yuu from the program. Alma hears this conversation and rescues Yuu, although he is captured by CROW guards in the process.
After landing in a sewer, he is washed up in front of a younger Bak Chan and Noise Marie. Eventually, after a brief exchange, Kanda is taken by the members of CROW to be "terminated" for learning the truth about the Second Exorcist program. The "procedure" proves a failure as Kanda's past memories of an unknown woman reanimate him, allowing him to summon the Innocence of Mugen in sword form which he uses to free himself. As he is escaping, he finds an injured Marie and while examining his wound, his blood starts to heal Marie. Kanda decides to take Marie with him in his search for Alma but upon finding him discovers that Alma has killed the staff of the Asian Branch and the members of CROW with his newly-acquired Innocence. A battle ensues between a psychotic Alma and Kanda resulting in Yuu's arm being cut off. As Alma explains his reasons for murdering everyone, he attacks Marie and impales Kanda, leading him to find the resolve to deal a menacing blow to Alma.
Abilities
Kanda can recover much faster than ordinary humans and withstand the blood of Akuma due to a secret skill created by the Chang family. He is also seen being able to rebirth after death approximately during 580 seconds, reproduce falling limbs, and have abnormal physical strength.
Innocence
"Mugen" (六幻, Six Illusions). Kanda wields a sword with supernatural powers. He runs his index and middle fingers along the back of the blade to activate it, saying "Mugen Unsheathe, Innocence Activate," which turns the blade silver. The shape of the sword has changed throughout Kanda's timeline. During his childhood, it took the form of a small butcher blade with multiple small wings on the hilt. Upon Kanda's introduction in the beginning of the series, it took the form of a chokuto with a black cross-emblazoned hilt and sheath, but after his battle with Skin Bolic, it was reforged into a traditional Katana.
Kaichū: Ichigen (界虫「一幻」English dub: Underworld Creatures, First Illusion, lit. Hell's Insects: First Illusion): Kanda swings his sword and releases a small swarm of supernatural creatures that devour his opponents.
Nigentou (二幻刀, lit. Double Illusion Blades): Kanda covers his sword and scabbard in a coat of energy and generates an energy blade, creating two impossibly sharp weapons. The second blade that he creates over his scabbard can also be just a pure energy blade if the scabbard is not used.
Hakka Tourou (八花螳螂, lit. Eight Flowers Praying Mantis): Using Nigentou, Kanda quickly slashes the enemy eight times. The slashes collectively resemble a flower.
Shouka (昇華, lit. Sublimate): Kanda activates the power of his tattoo, and his pupil changes into three dots. Veins also rise around his eyes. Once Shouka is activated, Kanda can activate Sangenshiki.
Sangenshiki (禁忌 「三幻式」, lit. Three Illusions): Kanda drastically increases his speed and strength at the cost of some of his life.
Consume, Mugen: Kanda reconstructs a broken Mugen by reconnecting the pieces with energy. Mugen appears to fall apart after one slash, however.
Bakuhakuzan (爆魄斬, lit. Explosive Spirit Slash): Kanda needs Sangenshiki to be active to use this, and makes a slash that seems to create small explosions and is strong enough to cut through a Level 4 Akuma. Kanda can also use it with the Fifth Illusion Style.
Fourth Illusion Style: Kanda's pupil changes to four dots and he gains another drastic increase in speed and power.
Fifth Illusion Style: Kanda's hair changes to a shade of light purple and stands up straight, while Mugen's blade glows with a different color and emanates large amounts of electricity. It uses a large amount of Kanda's life. The effects of this sword also seem to give Kanda a need for destruction while sealing up the rest of his emotions, leaving only his anger. When he uses the maximum power of the fifth illusion style, the sword takes the same form as when he was a child (small butcher blade with multiple small wings on the hilt).
Ripping Flash Claw: Kanda unleashes seven sharp energy beams.
