Kira, Izuru

吉良イヅル

Izuru Kira was born into a family of minor nobility, with his parents having passed away when he was still young. During his time at the Shinigami Academy, Kira became friends with Momo Hinamori, Renji Abarai, and Shūhei Hisagi, and the group was frequently seen spending time together. Following graduation, Kira, along with Renji and Momo, was assigned to the 5th Division, where he remained until Gin Ichimaru assumed the role of 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 demonstrates that his loyalty knows no boundaries when he defends his captain while she is in a grief-induced rage over her own Captain's apparent death. Despite this, he refers to himself as a "monster" afterwards for raising his sword against her.
Kira's Zanpakutou is Wabisuke. Its Shikai command is "Raise your head." When activated, Wabisuke's Shikai bends the blade into a square hook. 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 Zanpakutou.
