Izuru Kira

is the Lieutenant of the 3rd Division in the Gotei 13, under Captain Shūsuke Amagai (anime only).

History
Izuru Kira was born to a family of lesser nobility, his parents having been dead since he was young. While in the shinigami academy, Kira befriended Momo Hinamori, Renji Abarai, and Shūhei Hisagi, and they are often seen spending time together. After graduation, Kira, along with Renji and Momo, was sent to the 5th Division, where he stayed until Gin Ichimaru became captain of the 3rd Division. Kira is loyal to both his friends and his duties, perhaps to a fault. Despite the close friendship he shares with Momo Hinamori, Kira shows that his loyalty knows no boundaries when he defends his captain while she is in a grief-induced rage from her own captain's apparent death. Despite this, he calls himself a 'monster' afterwards for raising his sword against her.

Soul Society Arc
Kira is first seen attempting to find Renji, who leaves a lieutenant meeting to fight Ichigo Kurosaki. During Sōsuke Aizen's plot against Soul Society, Kira plays a role as a significant, yet clueless, puppet. His loyalty and dedication to following orders are used against him by Gin. Later on, Kira battles and loses to 10th Division lieutenant Rangiku Matsumoto, his weight-affecting zanpakutō rendered useless by her zanpakutō's ability to dissolve into ash. During the anime's Bount arc, Kira rescues Ichigo from the Bount Koga Gō, and later helps Ichigo fight his way into the Bount hideout. He is left to guard the entrance to the Seireitei following the successful infiltration by the Bount.

Fake Karakura Town Arc
When Aizen along with his three top Espada attack fake Karakura Town, he along with Yumichika Shūhei Hisagi and Ikkaku Madarame are left to protect the four pillars that keep the real Karakura Town in Soul Society. He begins a battle with one of Barragan's Fracción, Avirama Redder.

Avarima originally had the upper hand in battle due to his flying ability and being able to fight at a distance while Kira's attacks only work on close combat. He was eventually defeated however and was beheaded by Kira.

Powers and Abilities
Kido Practitioner

Zanpakutō
Wabisuke (Apologizer):


 * Shikai: Its shikai command is "Raise your Head". When activated, Wabisuke's shikai bends the blade into a square hook.


 * Shikai Special Ability: In this form, Wabisuke doubles the weight of whatever it strikes. The ability affects both inanimate objects and living beings. Though a seemingly pointless ability in sword combat, the effect is cumulative. With a second hit from Wabisuke, the weight will double again and so on, exponentially. Thus, after seven or eight blocked attacks, his opponents are unable to lift their own swords. Once Wabisuke's effect becomes noticeable, Kira's opponents often fall to their knees with their heads bent down, as if in apology, thus the name of Kira's zanpakutō. He then uses the unique square hook shape of his zanpakutō to behead his opponents, like a type of upwards guillotine.


 * Bankai: Not Yet Achieved
