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. 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.

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.Also he appearently uses a dog body for his gigai rather than a human body

History
During the Soul Society arc, he fights Kenpachi Zaraki with Kaname Tōsen, while their subordinates fight Ikkaku Madarame and Yumichika Ayasegawa. They couldn't defeat Kenpachi even when fighting together, and after Kenpachi defeats Tōsen's bankai, Komamura fights him with his own bankai. It was only when Komamura sensed Yamamoto was in danger that he left the battle. Komamura has a close friendship with Tōsen, and was very shocked when the latter chose to side with Sōsuke Aizen, feeling that his friend had abandoned his morals. Komamura confronts Aizen but is quickly defeated. Komamura later decides to awaken Tōsen with his own hands.

Zanpakutō
Tenken (Heaven's 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 strenght 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. Like 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.
