Yachiru Kusajishi.

Canon Claim
Name: Yachiru Kusajishi.
Race: Shinigami.
Appearance:Eleventh Division Lieutenant Yachiru Kusajishi's appearance is that of a very small, young girl with pink hair, pink eyes and a perpetual blush on her cheeks. She wears the normal Shinigami robes, and thus far we have only seen her with the Lieutenant insignia on her arm. She appears to be the youngest as well as the smallest among the captains and lieutenants.
personality:

Yachiru is child-like in most aspects, as she is small, cheerful, energetic, and carefree most of the time. She is often seen latched onto the back of her captain, Kenpachi Zaraki ("Ken-chan" as she calls him, "Kenny" in the English Dub and manga), just over his left shoulder, and is somewhat territorial about this position. She is surprisingly intimidating at times, especially when annoyed. Like Kenpachi, she has no sense of direction, but even so he relies on her for directions. Yachiru resents being criticized in any way and will often attack the perpetrator. Further reflecting her child-like nature, Yachiru likes to give people nicknames. For example, she gave Makizō Aramaki the name "Maki-Maki" and later when he reminds her of that name she finds it funny. She later renames him "mini-mustache". She also calls Ikkaku Madarame Baldy.^[4]

Yachiru's favorite free-time activity is eating sweets, though she will eat pretty much anything. She attends Head Captain Yamamoto's tea sessions, Captain Unohana's ikebana lessons, and also Captain Kuchiki's Calligraphy Club, but only to eat up the snacks and cakes served during these occasions and then disappear within moments.

It is also known that Yachiru's specialty is infiltration, which she uses mostly for mischievous deeds. During the time when Kenpachi takes his usual afternoon nap, she goes to play around Seireitei. She appears to have dug secret tunnels through the Kuchiki house, as she was seen searching for Ichigo Kurosaki ("Icchi" as she calls him), to show them to him. The tunnels are shown again when Lieutenants Isane Kotetsu and Nemu Kurotsuchi try to take a photograph of Byakuya Kuchiki.

Yachiru is the president of the Shinigami Women's Association, and holds its funds as such, spending it mostly on toys and candies. She stores her "treasures" in the hideout on the Kuchiki grounds mentioned above. It seems that she uses the whole Association to order the other members around, who are doing various, mostly childish pranks and other "tasks" to please her.

Yachiru seems to show a little-girl crush on Byakuya Kuchiki. She refers to him by affectionate nicknames like "Bya-kun" and "Byakushi," invites him to come eat with her (which she never asks anyone else) and at one point is seen offering him her drool-covered lollipop. Byakuya seems to find her crush annoying and mostly ignores her, although he apparently keeps buns on hand to jam into her mouth if she gets too assertive. In a recent omake, she has been seen dressed up in a cat costume, catching the koi in Byakuya's pond and releasing them in Ukitake's pond. While visiting Jūshirō Ukitake and "helping" him finish his food, Rukia mentions that there are no more koi in the pond, which Byakuya is upset about.


History: Yachiru first met Kenpachi in one of the worst districts of Rukongai, the 79th district of the North Alley, Kusajishi, as a nameless child. She crawled over to him after he had killed several other men with his unnamed Zanpakutō, and was completely unfazed by the violence she had just witnessed, or the blood on his sword. Even as Kenpachi warned her that the sword was dangerous, she reached out and touched it, giggling as her hand was covered in the blood of dead men. He adopted her after that, saving her from certain death in Rukongai. He named her "Yachiru" in memory of the only person he ever admired. Her surname Kusajishi was given to her because she's from that district. Since that day she has spent much of her time clinging to his back for transport.

Powers & Abilities:

High Spiritual Power: She is capable of emitting a great amount of spiritual power when she is angry, which forms into a large, pink, angry cat face.^[26] She also seems to be unaffected by her captain's vast spiritual pressure. Despite her childlike appearance and immature personality, Yachiru is apparently quite strong, since she is the current lieutenant of the combat division within Soul Society. Grown men have been shown to be afraid of her, and Rangiku Matsumoto was able to scare Ikkaku Madarame by threatening to tell on him to Yachiru if he didn't stop harassing Keigo Asano. Like her hair, Yachiru's spiritual pressure is pink.

Infiltration Expert: Yachiru is an expert at infiltration, which she only uses to undertake mischief.

Enhanced Strength: She is strong enough to easily lift Kenpachi, who is almost twice her height and over five times heavier, and leap between buildings while carrying him.

Flash Steps: Yachiru is also incredibly fast despite her compact size, running from the ground-level area of Seireitei to the mountain that holds the execution grounds in a fairly short period of time without Shunpo. In the anime however, she use what appeared to be Shunpo when she is chasing Ashisogi Jizō.^[27]

Detection and Analysis: Yachiru has displayed some detection and analysis skills with reiatsu. She detected and found Orihime when the latter was with Aramaki by noting the similarities between her reiatsu and that of Ichigo. From this she deduced that Orihime was a Ryoka.^[28]

Zanpakutou:

The name and ability of Yachiru's Zanpakutō are both unknown. She carries it around with a loose cord, rather than at the sash of her uniform. Her Zanpakutō's scabbard is also unusual in that it has a pair of wheels for transport, which were installed by Ikkaku Madarame, who turns out to be handy with tools, after she continually pestered him to do it.^[29] The tsuba is shaped like a flower.
