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 the 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.
