Ashiko

Xiaoyu (小雨; Xiaoyu) was a shinigami who was chosen by the Commander-General to be in charge of dealing with the escaped kenrei. She has been told that the kenrei should not be allowed to be in contact with anyone outside those who participated in the Kenrei Experiments, and concluded that the best way to achieve that would be to destroy the evidence that the surviving test subjects existed, which implied the deaths of the surviving kenrei.

Behind the scenes
The name was chosen to be Xiaoyu mainly due to a lack of naming inspiration on part of her creator. The character was created mainly to fill in a vital leadership role in the story Bleach: The Nobodies.
