President of the Shinigami Women's Association
|Voice actor||Stevie Bloch|
Yachiru Kusajishi is the lieutenant of the 11th Division in the Gotei 13, under command of Kenpachi Zaraki. Oddly enough, she is also the President of the Shinigami Women's Association. Yachiru is currently one of few lieutenants to have yet reveal the name of her zanpakutō.
Yachiru has short, bright pink hair, wide brown eyes and rosy cheeks. Compared to most other shinigami, Yachiru is extremely short, which is exaggerated especially in comparison to Kenpachi Zaraki, whom she is often seen riding on his back. It is assumed by her chidish appearance and personality that Yachiru is also the youngest of all officers in the Gotei 13. Yachiru wears the normal shinigami uniform and her division's crest on her left arm, which is common to all lieutenants. Unusually, she carries her zanpakutō by a string tied to her left arm.
Yachiru is generally very youthful and jubilant, however eccentric and childish in her mannerisms. On the other hand, she tends be somewhat irritable as well, primarily when she is watching Kenpachi fight, and especially when she's being criticized for any reason. Yachiru enjoys making nicknames for other characters such as "Kenny" for Kenpachi and "Ichi" for Ichigo Kurosaki. Having spent the majority of her life with Kenpachi, Yachiru has developed more of an infatuation for combat. Nevertheless, she has witnessed much bloodshed and lawlessness from a very young age, but peculiarly enough never seemed to be bothered by it. Subsequently, Yachiru was not even slightly intimidated by Kenpachi, who immersed himself in such a chaotic lifestyle, when they initially met. Conversely, she became attached to him, mostly because of the fact that he named her. Yachiru, who seems to have no more talent at sensing spiritual pressure than Kenpachi, has a horrible sense of direction and often leads Kenpachi astray. Yachiru is also incredibly wily and mischievous, digging several tunnels into Byakuya Kuchiki's (her crush) residency, and using the Shinigami Women's Association to satisfy an ever growing sweet tooth.
Yachiru has appeared to have had a violent past and most of her memories are spent with Kenpachi. Kenpachi and Yachiru's first meeting was in the 79th District of Rukongai, Kusajishi, hence her last name. Kenpachi had just finished slaughtering a group of men and sat down with a jagged, blood stained sword still on hand. An innocent little nameless girl then crawled up to Kenpachi and despite being forewarned, smudged some of the blood on her hand and giggled. Empathizing with the little girl, Kenpachi decided to adopt her, naming her "Yachiru" apparently after someone he admired. She eventually became the lieutenant of the 11th Division, possibly at the same time Kenpachi was named its captain after he killed the previous one.
Ability-wise, Yachiru is one of the least developed characters. Due in part to her small size, she is very speedy and agile. Inversely to her small stature, Yachiru is unusually strong, which is evident when she managed to carry a gravely wounded Kenpachi after his fight with Ichigo in Soul Society. Like her captain, she doesn't seem to have much, if any, talent for even the most basic shinigami techniques, making her position as a second-in-command officer questionable. On the other hand, she does have a craft for infiltrating secured places, though mainly for trivial purposes such as stealing sweets or spying on her crush, Byakuya Kuchiki. Nevertheless, as a lieutenant, it can be assumed that she has a considerably high spiritual pressure.
Unlike many high ranking characters, Yachiru has yet to reveal the name of her zanpakutō, much less used it in any way. Also, instead of the usual way of carrying a zanpakutō held under the sash by the left hip, Yachiru is unique in the fact that her's is held by a string attached to her left arm. It is shorter than most in order to accommodate her size, and it is carried in a pink sheath with wheels, which were installed (after much pestering) by Ikkaku Madarame. The hilt is also pink and the guard is shaped like a flowwer.
 Soul Society Arc
During the Soul Society Arc, Yachiru is first introduced as Kenpachi's subordinate. Although she does not play a major role in the plot of the arc, Yachiru is seen in almost any scene with Kenpachi. When Kenpachi is tracking others down Yachiru was directing Kenpachi through Soul Society, but gets him lost quite often.
Before Kenpachi's first fight in the arc with Ichigo, Yachiru first introduces herself to Ichigo, who she calls "Ichi". During the fight between Ichigo and Kenpachi, Yachiru watched excitedy from a distant building. Afterwards, Yachiru was worried after Kenpachi fainted from losing to the orange haired soul reaper.
Shortly after the fighting, Yachiru and Makizō Aramaki, who Yachiru calls "Maki-Maki", bring Orihime Inoue back to Kenpachi's resting area where they decide together to find Ichigo. After separating from the group, Yachiru leads Orihime, Makizō and newly escaped Sado, Ishida, and Ganju Shiba to Soul Society's execution grounds.
 Bount Arc
During the Bount Arc Yachiru plays less of a significant role in the plot. Kenpachi and Yachiru have a run in with former 11th Division soul reaper Maki Ichinose. Once again, Kenpachi tells Yachiru to get back before the fight begins. Yachiru watches from a distance and also must occasionally pace back due to the large effectiveness of Ichinose's Blinding Light ability. When Kenpachi defeats Ichinose he and Yachiru return to Seiretei.
 Arrancar Arc
Yachiru is seen in a flashback when Ikkaku Madarame is fighting Edrad Liones. Ikkaku confronts Kenpachi and Yachiru draws a picture on the ground depicting Kenpachi defeating Ikkaku laugh. Yachiru eventually watches as Kenpachi defeats Ikkaku. In a separate flashback during the same battle Yachiru, partnered with Kenpachi, Ikkaku, and Yumichika Ayasegawa have a competition to see who can cut off the most tentacles of a re-spawning Hollow.
 Hueco Mundo Arc
During the Hueco Mundo Arc Yachiru once again travels with Kenpachi to Hueco Mundo. Eventually Yachiru and Kenpachi are engaged in combat with Nnoitra Jiruga, the fifth Espada in Sōsuke Aizen's Army. During the battle Nnoitra is able to land a strong blow to Kenpachi, knocking him out. At this point Nnoitra advanced to Yachiru to attack, but Kenpachi is able to reawaken in time to cut-off one of Nnoitra's arms.
 Zanpakutō Unknown Tales Arc
It was mentioned by Ikkaku Madarame that Kenpachi and Yachiru were away which explained the reason why they did not appear on Sōkyoku Hill along with the other captains and lieutenants.
