Cang Du

is a Quincy and a member of the Wandenreich's Sternritter with the designation "I"-.

Appearance
Cang is a fairly slim man with narrow eyes and short, dark hair, with pointed bangs that hang between his eyes. He has a small, vertical scar over the left side of his mouth. His attire is a variation of the Sternritter's typical white uniform, consisting of the order's signature hooded cloak, a thigh-length trench coat, and a pair of black fingerless gloves.

Personality
Cang Du is a stoic individual, especially in comparison to some of his Sternritter comrades. Cang had very little reaction to the news that Yhwach had appointed Uryū as his successor, despite him being a new recruit, while the news caused anger among his comrades. Cang is a very cold man, who believes strictly in iron-clad principles, such as 'those who lived together should die together', and he tries to enforce as such. He doesn't believe in pantheism, and claims that a Bankai has no soul.

The Thousand-Year Blood War arc
Upon receiving the orders of Yhwach, Cang Du and the other Sternritter gather at the Gate of the Sun before traveling to the Seireitei in order to participate in the conquest of Soul Society.

Once there, he and the others create pillars of blue flame prior to engaging the Shinigami in battle. Cang encounters the captain of the 10th Division, Tōshirō Hitsugaya. When Hitsugaya activates his Bankai, Daiguren Hyōrinmaru, Cang uses his medallion to steal it. During the course of their battle, the Quincy uses the captain's Bankai against him. When Captain-Commander Genryūsai Shigekuni Yamamoto activates his own Bankai during his fight against Yhwach, all the water in Soul Society begins to evaporate, including the ice which composes the stolen Bankai. When Ichigo Kurosaki later arrives in Soul Society, Cang is surprised when his Reiatsu abruptly vanishes.

Later, after the Wandenreich's retreat from Soul Society, Cang is present when Yhwach declares that Uryū Ishida will be his successor. Following the announcement, he, Bazz-B, Mask De Masculine, and BG9 discuss the announcement, with Cang remaining silent.

During the Wandenreich's second invasion of Soul Society, Cang arrives on the scene just as Bazz-B is about to attack Hitsugaya, reminding Bazz-B that they promised to leave the captains to the ones who stole their Bankai. Cang then moves forward, stating that he will have the final blow. As Cang moves in on Hitsugaya, Bazz-B comments that he will be punished by Yhwach for stealing his prey. Cang replies however that it was Yhwach who decided as such. He then opens his cloak, dropping an unconscious Rangiku Matsumoto onto the floor. Saying the two of them should die together, Cang reveals himself to be The Iron.

Activating Daiguren Hyōrinmaru, Cang comments on how it is a beautiful Bankai that lived alongside Hitsugaya. He says that stealing only his Bankai and letting it live on after Hitsugaya's death, makes him sorry.

When Hitsugaya touches the Shin'eiyaku pill sent to him by Kisuke Urahara, Cang asks him what it is. As the pill takes effect, one of Daiguren Hyōrinmaru's wings snaps off in a splatter of blood, with Cang appearing shocked. As this happens Cang checks his medallion only to determine that it is working normally, so he is further confused as to why Hyōrinmaru is starting to return to Hitsugaya. As he regains part of the ice wing that Cang lost, Hitsugaya states that while he doesn't know, perhaps his Bankai just wishes to return to him.

Cang begins to attack and points out that the Sternritter are taught to control the Bankai they have stolen. He attempts to attack Hitsugaya with ice but it redirects itself before reaching him. Hitsugaya tells him not to overdue it as it cant attack itself. As he continues to attack Cang notes that Hitsugaya has used the tactic as well previously and should stop talking as if Bankai have a soul. Hitsugaya questions this way of thinking before he suddenly hears the voice of Hyōrinmaru, to which he remarks that its been a while since he heard him and welcome back. Hyōrinmaru fully returns to him, taking on some darker manifestations, reflected in the ice armor. Hitsugaya states that he thought Hyōrinmaru's face was a pain but then he remembered that the Bankai Hollowfied for a few seconds, so he'll have to deal for the time being. Cang attempts an attack but much to his surprise Hitsugaya counters the attack stating that the cross-shaped flower is Hyōrinmaru's crest. As Cang is encased in a giant cross-shaped flower, he apologized for not making it a pentagram.

Equipment
Medallion: Cang possesses a round, unnamed device which is roughly the size of a person's palm and has the Wandenreich insignia etched onto its surface. When activated, the device can steal a currently released Bankai in the immediate vicinity, as evidenced when Cang used it to take Tōshirō Hitsugaya's Daiguren Hyōrinmaru. Afterwards, the medallion's owner can use the stolen Bankai's power at will.

Powers & Abilities
Great Spiritual Power: Cang Du's spiritual power is on a level comparable to or greater than that of a captain-level Shinigami.

Reishi Absorption: As a Quincy, Cang can absorb spirit particles from the atmosphere and combine them with his own spiritual energy to form weapons and use different techniques.

Spirit Weapon
Reishi Claws: Using his abilities as a Quincy, Cang can concentrate spirit energy and particles and form them into weapons. His favored weapon is a claw with four curved blades, which he wears on the back of either wrist.

Quotes

 * (To Tōshirō Hitsugaya) "Those who spend their lives together should remain together in death. That is my belief."
 * (To Tōshirō Hitsugaya) "This is your Bankai. Doubtless you have never had the opportunity to see it from this perspective before. It is quite a beautiful Bankai. And of course... This Bankai too is "one who lived by your side." It pains me greatly... that I must take it for my own... thus allowing it to live on under a new master... long after you are dead and gone."
 * (To Tōshirō Hitsugaya) "Pantheism is not for me."
