Shūsuke Amagai

, sometimes romanized as Syūsuke Amagai, was introduced as the new Captain of the 3rd Division (anime only).

Appearance
Shūsuke Amagai has a rather unkempt appearance to himself, due to his messy hair and chin stubble. He is a tall muscular Shinigami who has chin-length blueish hair that he wears in a somewhat ragged fashion. As opposed to his predecessor, he wears a long-sleeved captain's haori. Aside from the extra sword holster and the strange paper that he keeps in the fold of his uniform, his outfit is a standard Shinigami uniform.

Personality
Amagai is shown to be incapable of holding his drink, collapsing even after eating sake-flavored pickles, and acting irrational after smelling the scent of sake in the air. Although he was initially looked down upon by his fellow division members, Captain Amagai's methods have since earned their respect. He also seems to favor teamwork and coordination between individual fighters, as he used these methods in the Patrol Corps, and teaches these methods when training his squad.

History
He was originally born under a different name, for he was the son of 1st Division member Shin'etsu Kisaragi. One day he realized something was different about his father and went looking for him, eventually finding his father at the area where he trained with his zanpakutō. Upon dying, he learned that his father was killed by Shigekuni Yamamoto-Genryūsai. He also heard his father speak a peculiar word: Bakkōtō.

Several years later, he entered the Gotei 13 and changed his identity in order to learn the truth behind his father's death. He claimed that he came from Rukongai and he took on a new name: Shūsuke Amagai. After becoming a Shinigami, Amagai continuously gathered information and researched the bakkōtō. He eventually learned of what the bakkōtō were and that they were secretly being manufactured by the Kasumiōji Clan. He then concluded that his father was killed because he wast trying to learn the truth behind the bakkōtō. Because he thought that Yamamoto killed him to cover up the bakkōtō, he swore revenge on the Captain.

For many years Amagai trained in order to take his revenge upon Yamamoto. During those years, he also gained the trust of the Kasumiōji Clan and was given his tuning fork bakkōtō by Gyōkaku Kumoi. He eventually made his way into the Patrol Corps and rose through their ranks.

Shūsuke Amagai eventually became the new Captain of the 3rd Division, taking over after Gin Ichimaru's defection from Soul Society. He became a captain via the. It is known that he had to fight Kenpachi Zaraki, but the other Captain is still unknown. Most likely he was presented with eligibility by Captain Soifon, as the Patrol Corps is a division of the Onmitsukidō and to any other Captain he would have been largely unknown, except to her. According to Sajin Komamura, promotion of a Captain from the Patrol Corps is unprecedented. Amagai's promotion implies that substantial changes are taking place in Soul Society.

New Captain Shūsuke Amagai arc
During an official Captains' meeting Shūsuke was introduced to his new peers as the new Captain of the 3rd Division. Once the meeting was over he headed over to meet his new subordinates, and introduced Makoto Kibune whom he appointed as the new 3rd seat. Izuru Kira kept the position of Lieutenant as a way of smoothing the transition and integrating the unit. Most of the 3rd Division members could not readily accept a complete stranger as the Captain. Shūsuke sympathized with them, stating that as long as he was their Captain he would always protect them. Later during a welcome party thrown by Izuru Kira, Shūsuke made a toast, but became drunk after one bowl of sake and passed out.

Shortly after, the 3rd Division was ordered to take care of some Menos Grande. Since the Captain is passed out, the rest of the division sortied under the command of Kibune and Kira. The fight against the Menos went well, but the division was endangered when they encountered a cleaner. Shūsuke turned up to rescue his division, blowing away the cleaner with a tremendous amount of power despite being drunk. Thereafter the division began to respect and trust him.

Having realized that the 3rd Division had been too dependent on Gin Ichimaru, Captain Amagai began to train the members of the squad to work together as a team under him. Inspired by the success of his training methods, Shūsuke made a request to Commander General Yamamoto to start inter-division training sessions so that the Gotei 13 could better coordinate its divisions. The idea was initially unpopular among the other Captains, particularly Kenpachi Zaraki and Mayuri Kurotsuchi, both of whom did not believe that they should have to be concerned with the problems of the other divisions. Although the idea was initially turned down, General Yamamoto secretly tested Captain Amagai's coordination skills by releasing fake Menos Grande into Seireitei, so that he could assess the reactions of the new Captain and the different divisions. Shūsuke responded by effectively coordinating many squads, resulting in the approval of his initial proposal.

He nominated the third division to capture Ichigo Kurosaki. Due to his lack of familiarity with Ichigo, he would be able to fight at full strength, as opposed to other Captains who had fought alongside Ichigo and might hold back. Rukia Kuchiki immediately noted that Amagai represented the most dangerous choice, as they might have been able to talk down another, more familiar Captain. Amagai began to fight Ichigo, but Shū Kannogi came between the two. Startled by this turn of events, Amagai accepted Shū's story and decided to help rescue Rurichiyo and bring down Kumoi.

After helping Ichigo find Rurichiyo, he revealed his true reasons for doing so: he kills Kumoi, takes the princess and the Bakkōtō nuclei, and teleported to where General Yamamoto is. As Kumoi lay dying, he wondered why Amagai cut him down, mumbling that he had "done everything he said."

Amagai faced down Yamamoto at his office, revealing his hand in the events that plagued the Kasumiōji household. Kenryū and Enryū arrive to save Rurichiyo and try to subdue Amagai, but they are no match for him. Yamamoto demands to know Amagai's motives, setting off a flashback. Amagai reveals that Yamamoto killed Amagai's father, Shin'etsu Kisaragi, to keep secret the Bakkōtō and Yamamoto's involvement with the Kasumiōji clan to secretly allow them to create Bakkōtō. In order to take his revenge, Amagai joined the Shinigami and rose through the ranks, waiting for his time to strike. He also forged an alliance with the clan, intending to betray them as well when the time was right.

Having heard enough, Yamamoto unleashed his Shikai. However, Amagai used the collected Bakkōtō nuclei to feed his own tuning fork weapon, which was revealed to be a very strong Bakkōtō with its nucleus hidden in its hilt. Using the Bakkōtō, Amagai sealed Yamamoto's spiritual powers, and then unleashed his Bankai, Raika Gōen Kaku. Yamamoto looks severely disadvantaged until Ichigo arrived and interfered. Amagai freely admitted his intentions to kill both Yamamoto and Rurichiyo. Declaring that Amagai hurt too many innocents to complete his plans, Ichigo explained that regardless of whether Amagai's vendetta was just, he had to be stopped for the sake of the innocent Rurichiyo.

The two fought, and Amagai attempted to neutralize Ichigo's powers as he did with Yamamoto. However, the process was nowhere near completely effective, which surprised and confused him. Finally, Ichigo manifested his Hollow mask, allowing Amagai to understand: his bakkōtō could not neutralize Hollow powers; only Shinigami powers. Despite this, Amagai fought on for some time before being flattened by Ichigo's Getsuga Tenshō. Surviving this, he dug himself out of the rubble and prepared to feed his reiatsu to the bakkōtō to grow even stronger.

After a continued battle with Ichigo, his Bakkōtō was finally damaged and its effect was voided. Amagai, still with what little strength he had left, was determined to kill Yamamoto, even though his Zanpakutō had reverted to its sealed form. He then proceeded to impale an unfazed Yamamoto on his sword just as the other captains and lieutenants arrived. Yoruichi Shihōin then explains the truth of what happened so long ago.

Years ago, Yamamoto realized that Kumoi was using the techniques of the Kasumiōji family to make the forbidden bakkōtō and test them on humans, but was forbidden from doing anything by the Central 46 Chambers. Instead, Amagai's father, Shin'etsu Kisaragi, who was a pupil and member of the 1st Division, offered to go on a secret mission for Yamamoto. When Kisaragi found the Bakkōtō, he was captured by Hanza's assassins and his will was forcibly taken over by the bakkōtō. Kumoi then commanded Kisaragi to kill who sent him, as a means to test the Bakkōtō's power and its effect on humans, and thus with no way to save his pupil, Yamamoto was forced to take his life. With no proof of the Kasumiōji clan's illegal activities and being forbidden to interact with them Yamamoto, could do nothing more then cover up Kisaragi's death and bury what he knew of the clan, as well as the secret mission. The cover-up turns out to be what Amagai later found in the records while he was training in the Seireitei.

Realizing that he made a terrible mistake, Amagai remembers his fathers dying words telling him to "beware the Bakkōtō". Feeling ashamed for his actions, Amagai resolves to end his life because his pride was too great to bare his weakness. He consumes himself in the fires of his Zanpakutō. Before doing so, he apologizes to Izuru for all the trouble and told him he enjoyed his time with him and the 3rd Division.

Powers & Abilities
Master Swordsmanship Specialist: Having fought against a master swordsman of Kenpachi Zaraki's caliber and not sustaining any known injuries demonstrates Amagai's prowess as a swordsman. He was later shown to fight very effectively, putting considerable amounts of strength behind his attacks and also able to counter attacks from various angles.

Zanpakutō

 * In its seal form it resembles a small sword such a kodachi. It has a olive green handle with a bronze bow-shaped guard. He carries it in a red scabbard attached to a strap hanging on his waist.


 * Shikai: Raika's release command is . Amagai holds his Zanpakutō upside down behind his back calls out the release command in it's Shikai, Raika takes the form of a white longsword with a hook at the end and curved shell-like pipes that forms the hilt. Upon transformation flames emit from the pipes accompanied by a trumpeting sound.


 * Shikai Special Ability: The pipes emit fire, heating the blade and causing it to take on a more fiery color. Amagai can then focus fireballs into the crux of the hook and, by slamming it into the ground, he create large fissures of flame that travel to the enemies at fast speeds. Its attack power is shown great enough to counter the Shikai of Hyōrinmaru, the most powerful ice-based zanpakutō.


 * Bankai: : Amagai holds out his zanpakutō in front of him as fire swells around him. Raika becomes a large and more detailed version of its former self. Raika Gōen Kaku takes the form of an enlarged sword and turns the edge of the blade a crimson red color with a hook at the end; the inner side of the hook-blade sports several jagged edges. A large white shell with a light-purple trim like massive hollow pauldron/shield with the handle is hidden behind it. The sword is about as tall as Amagai in this form.


 * Bankai Special Ability: In this form the sword's blade becomes fiery, and fire shoots from the pauldron when its powers are being used. The sword's blasts of fire are much more potent, large and powerful in this form, and the pauldron on his sword can be used as a means of defense as well. The abilities of the Zanpakutō are known to create fissures of fire with devastating effect. It is capable of creating a large wave of fire rushing forward and further destroying any enemy that becomes enveloped in the flames. While in this form the pauldron acts as a high intensity flame thrower when it is turned toward an opponent.


 * Amagai twirls his sword above his head, and the blade becomes fiery and flames shoot from the pauldron, while lightning builds and he then slams the blade into the ground accompanied by a lighting strike. The ground begins to shake as multiple fire spears shoot from the ground at varied angles to to trap the opponent in a prison of flames. However, a side effect of this techique is that it leaves Amagai looking very tired.


 * Amagai lifts his sword over his head and its entirety is inflamed. He then strikes it toward his opponent allowing him to send a giant fireball at the opponent.


 * He uses the tip of his sword to fire out a multitude of fireballs toward his opponent.

Bakkōtō
Tuning Fork Form: A unique weapon taking the form of a large white tuning fork. The abilities that have been attributed to it consists of the ability to emit large green waves of spiritual energy, with amazing destructive potential towards its target. Another ability can be activated by striking it against the hilt of his zanpakutō, causes it to emit a blade of concentrated spiritual energy. The weapon has been shown to be powerful enough to destroy one of the dimensional cleaners in the Dangai Precipice World.


 * True Form: It is later revealed that this is a Bakkōtō. Its eye nucleus is hidden within the bottom of the hilt. It is unique in that it feeds on the nuclei of other Bakkōtō. By tapping the tuning fork, while holding it upside down, it causes the nuclei to release by extending itself like a tendril up and around Amagai's right arm, transforming into a armored black gauntlet shaped in form of a dragon. From the initial release, the gauntlet can fully encompass the entire arm, creating a claw on the hand. A sash-like component comes over Amagai's left shoulder and down to his waist, containing five Bakkōtō nuclei. Attaching the armored right arm and the sash is something reminiscent of a dragon's tail that hangs freely from the upper shoulder area of the back.


 * Bakkōtō Special Ability: When in use, it extends down and generates a spiritual energy blade from what resembles a dragon's mouth. When thrust into the ground, it sends out a resonating pulse capable of totally negating a Shinigami's powers. The power works by cutting a Shinigami off from his/her connection to spiritual energy, effectively making every zanpakutō in the vicinity useless as long as the power is active. This can also be done by striking a zanpakutō directly. However, the ability does not affect Amagai's own zanpakutō. In turn it also has almost no effect on Hollow powers such as Ichigo's Vizard state.

Trivia

 * Amagai appears in the Bleach video game Bleach: Versus Crusade. He is one of the very few non-movie/anime-only characters to be featured in a Bleach video game, the only other character being Ririn, who is playable in Bleach: Dark Souls.
 * So far Amagai is the only person to strike Shigekuni Yamamoto-Genryūsai onscreen.
