Sajin Komamura

is the Captain of the 7th Division of the Gotei 13. He has the appearance of an antropomorphic canine, making him easily the Captain with the strongest build-up, except for maybe Kenpachi Zaraki, and the largest captain. For a long time he was self-conscious about his appearance, and used to hide his face behind a helmet. After the revelation of the three traitorous Captains, of which Kaname Tōsen was his close friend, he does not wear a helmet anymore. His Lieutenant is Tetsuzaemon Iba.

History
While practicing once in an open grassy area, Tosen chances upon someone, and because he is blind, had no idea where the person was. It was only when Komamura spoke that he realized he had talked in the wrong direction. Complimenting Komamura’s ability to hide his presence so well, Tousen said that he had never been able to not feel someone’s presence before, even though his eyes cannot see. Komamura was highly touched, for this was among the first times that he was not looked upon as an outcast.

It is unknown where Sajin originated though Shigekuni gave him the opportunity to join the gotei 13 even if hes not human, evidence has that he was human before and probably used gigai.

Later they meet time and again during their time in the Gotei 13 Squads, and Aizen is also introduced to Komamura via Tosen’s recommendation.

Soul Society arc
Note:This synopsis section is fully detailed on every scene of the characters appearance,unlike most of other synopsis,it has characters talking and its not a summary.

Komamura Sajin first appears at the emergency Captain meeting that questioned Gin Ichimaru’s apparent slip of duty in letting the Ryoka go. Standing next to Kaname Tōsen and Sōsuke Aizen his relatively bigger size was readily apparent, but beyond that little is known of him except that he wears a sort of helmet.

After Aizen’s death,Komamura visits Aizen’s body in the 4th Squad Relief Station, accompanied by Tosen, whom he appears to be rather close with. He still has not spoken at this point of time.

The first time he speaks is on the day of Rukia Kuchiki's execution itself. As Tetsuzaemon Iba, his lieutenant, rushes towards Komamura, landing in a kneeling position and apologizing profusely for his latecoming, Komamura stops him in mid-sentence. He says that he knows Iba understands that he needed time to think through his own thoughts, for Komamura had reservations about Rukia’s execution that Iba had already perceived. They were, however, overridden purely by Komamura’s deep gratitude for Shigekuni Yamamoto-Genryūsai.

Komamura reveals at this point that because of his appearance, he was always an outcast. Yet Yamamoto took him in and took care of him, and because of this Komamura always strives to do something for Yamamoto. It is the same reason that has driven Komamura to become a Captain among the Gotei 13 Squads.

At this time Tosen appears with Shūhei Hisagi, his lieutenant, and Komamura asks him whether he holds the same view. Tosen merely replies that his eyes reflect the path of least blood and that he believes he walks the same path as Komamura.

Later, Komamura, Iba, Tosen and Hisagi stop Kenpachi Zaraki and his group in an open courtyard. Going through the verbal sparring, Zaraki is left with Tosen and Komamura. Komamura, getting tired of Zaraki’s arrogance, unleashes Tenken upon Zaraki, and Tosen follows that up with Benihikou. Despite the heavy damage however, Zaraki laughs off the attacks and the three start fighting.

Despite their attacks, Komamura and Tosen are thrown about. Zaraki sneers at Komamura and asks him to release his Bankai and fight him. Komamura is greatly angered and answers that he does not require Bankai to fight a traitor like Zaraki. It is at this point that Tosen begins speaking to Zaraki, telling Komamura first that he will “do it”.

Though Zaraki beats Tosen, Komamura stops Zaraki from killing Tosen, deflecting his blade with one arm and his helmet. Smashed in the process, the helmet falls to the ground in pieces. It is at this time that Komamura’s real appearance is revealed – he has the head of a fox, and his body is also a form of a humanoid fox’s. Releasing his Bankai at this time, Komamura faces Zaraki just as Rukia’s execution starts. After a short while, feeling that Yamamoto was releasing his own spirit power, he leaves the battleground to rush to Yamamoto’s aid.

Before he gets there, the message that Aizen and Tosen had betrayed Soul Society reaches him, and he rushes over to the Soukyoku Stand and jumps onto Aizen, who stops his blade with one hand. As Aizen calmly mentions that it has been quite a while since he last saw Komamura’s face, Komamura gets angrier and asks Aizen how he can still smile at this point in time, mentioning as well that he will never forgive Aizen and Tosen for betraying Soul Society.

Angered at their betrayal, Komamura finally asks Tosen for an explanation. Getting none, Komamura immediately does Bankai. However, under Aizen's Zanpakuto's hypnosis, he realizes too late that Aizen is right in front of him. Aizen then does a Hadou kido spell (Black Coffin) and defeats Komamura.

Komamura regains consciousness at the time of the three leaving, shouting for Tosen to get back down. “Why did you become a Shinigami?” he asks. ''“Was it not for your friend who died? Was it not for justice?” Tousen replies that he had told Komamura before that “all that is reflected in these eyes is the path of least blood. The path I walk is justice.”''

A week after that, Komamura stands in front of the grave of Tousen’s dead friend, asking her what she would have said to stop Tosen. Then, Hisagi makes his appearance, and Komamura is asked if Tosen will ever come back. “Without a doubt,” he replies. “By our own hands, let us open his eyes.”

Fake Karakura arc
When Aizen along with his top three Espada attack the fake Karakura Town, Komamura along with his lieutenant and the rest of the of the Gotei 13 Captains currently not in Hueco Mundo are seen awaiting for Aizen's arrival.

During the battles with Barragan's Fraccións, he steps in to save Ikkaku Madarame after his defeat at the hands of Barragan's largest Fracción, Pō. Komamura catches Pō off guard and punches him in to the side of a building. Pō, however, is immediantley back on his feet, unscathed, and is also unfazed by the captain being an animal. Pō then proceeds to punch him for several miles and releases his Zanpakutō. Sajin returns and stops an attack from the released arrancar, who was attempting to attack his lieutenant and Ikkaku, and proceeds to throw the him over his head and in to the ground. Pō, unharmed, says the hit made him "yawn", which is actually him building up a cero. Sajin then calmly releases his bankai and "crushes" Pō, killing him in the process.

Appearance
Komamura is an unusual character in that he is an anthropomorphic canine. He was initially very self-conscious about his appearance, but after his fight with Kenpachi Zaraki (during which his helmet was destroyed) in midst of the invasion of Soul Society, he gained enough confidence to go without the helmet.

Personality
Physically imposing, Komamura is a gentle giant. He is the quintessential loyal and grateful subordinate. His deep gratitude to Yamamoto for taking him in overrides all his own feelings, and for Yamamoto he will do anything, even die. Komamura is a serious man, deeply scarred by the times he was spurned by society for his appearance, yet undyingly loyal to the values he holds. Like Ukitake and Unohana, he is not tough or cruel with his squad, preferring to lead with impartiality.

An Omake shows him being pleased with the gift of a dog brush from earth, as he finds the brushes in Seireitei ineffective at brushing his fur.

Powers & Abilities
Enhanced Strength

Enhanced Senses: due to his animal-likeness he is seemingly in possession of superior senses.

Zanpakutō
Tenken (Heavenly Sword)


 * Shikai: Its shikai command is "roar".


 * Shikai Special Ability: In its shikai, Tenken creates various body parts of a fearsome armored giant to copy whatever body part Komamura moves; for example, should Komamura swing his sword, a gigantic disembodied arm wielding a sword appears and does the same thing. The body gigantic parts generated by the Initial Release possess strength and attacking power proportionate to their size, making Komamura's zanpakutō quite powerful.


 * Bankai: Kokujō Tengen Myō'ō (Heavenly Punishment of Kokujō's King)


 * Bankai Special Ability: brings forth the entire giant up to 100 meters tall. As in the shikai, the giant copies every movement made by Komamura, allowing him to deal colossal damage. There are times when after materializing his Bankai, Komamura has the option of being the giant itself, as seen in his battle with Aizen.
