Yachiru Kusajishi (草鹿 やちる Kusajishi Yachiru) of Bleach is the lieutenant of Squad 11.
She is most recognizable by her mid-length, bright pink hair. She is childlike in most aspects, as she is small, cute, cheerful, and carefree most of the time. She was found as an infant by Kenpachi Zaraki in the 79th District of Rukongai's North Alley, "Kusajishi", the second-most violent area of Rukongai compared to the 80th District "Zaraki".
Despite being drenched in blood and having just killed a large group of men, Kenpachi did not frighten her as she touched his blood-soaked zanpakuto unfazed. Kenpachi named her "Yachiru", in memory of the one person he ever admired, the current captain of the 4th Division, Yachiru "Retsu" Unohana.
