Izuru Kira

is the Lieutenant of the 3rd Division in the Gotei 13.

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.

Personality
Kira is a gloomy and introspective person, not easily given to socializing with others. He generally appears weak and diffident, leading many to believe he lacks ability as a leader. As an officer, he does not tend to inspire confidence or boost morale the way other lieutenants do. However, in combat he shows ruthless determination.

His personality flaws are also assets: his introspection coupled with his tendency to worry makes him indecisive, but it also makes him sensitive to unusual behavior. His loyalty to his comrades inspires him to great efforts in their defense, as seen when Momo Hinamori attacks Gin Ichimaru and again in the anime when Makoto Kibune's attacks endanger other members of the 3rd Division.

In the manga, it is revealed that Kira considers the essence of war to be despair, as exemplified by the symbol of his division, the marigold. He also hates to fight unless prompted or given orders. This is true when he faces and defeats Avirama Redder.

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.

Bount Arc
During the Bount Affair, Kira rescues Ichigo from the Bount Gō Koga, 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.

== Captain Shūsuke Amagai Arc ==

In the anime only story arc the 3th division gains a new captain, Shūsuke Amagai. Kira is unsure of this new captain but is quickly enthralled by him when he defeats the cleaner in the severing dimension single handily while being drunk from a earlier welcoming party. Kira then watches new training exercises the new captain creates, he is then paired with the new 3rd seat Makoto Kifune to stop run away hollows from the old hollow execution days. They stumble upon a 4th division member cornered by the hollows. They manage to force the hollows back but the member is injured and passes out. Kifune releases his zanpakto and mows down everything in his path including the 4th division member Kira stops the blade but Kifune rants on about how the weak should just die. All three are eventually rescued but the member is not expected to live due to the sheer injuries he sustained. Kira talks to his captain and he tells him to watch Kifune carefully, but must not to be seen. Kira then spots Kifune at the Kasumiōji house and enters the compound. He also find the kidnapped princess and when he see it he tries to free her but also finds assassins. Kira manages to take them down but could not not stop them from taking the princess. Kira searches for her but finds Kifune instead. Kifune releases his zanpakto and faces off against Kira. Kira manages to gain a small upper hand as he gets Kifune's zanpakto heavier but kifune makes his blade move even though it is very heavy revealing it is bakkutou that is making it move. Kifune nearly defeats Kira but manages to break kifune's bakkutou. Kifune tries to increase his powers with the bakkutou once more but dies in the process. Kira then faints from his injuries and is sent to the 4th division for treatment. He reappears at amagai's suicide asking for his captain to reconsider. He then gravies for his lost captain.

Fake Karakura Town Arc
When Aizen along with his three top Espada attack fake Karakura Town, he along with Yumichika Ayasegawa, 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. He then comes to the aid of Ikkaku but is told to stand down and return to his post.

Powers and Abilities

 * Kido Practitioner

Zanpakutō
''':


 * Shikai: Its shikai command is '''. 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. This seems to be a pointless ability in combat, but the effect is cumulative. Each subsequent hit from Wabisuke continues to double the weight.  Thus, after seven or eight strikes, his opponents are unable to lift their own swords (or their own bodies, as seen in the Bount Arc.)  Once Wabisuke's effect becomes noticeable, Kira's opponents often fall to their knees with their heads bent down, as if in apology, hence the name of Kira's zanpakutō. He then uses the unique square hook shape of his zanpakutō to behead his opponents, something like a type of upwards guillotine.


 * Bankai: Not Yet Achieved
