Ashiko (あしこ; Ashiko) 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.
Little about Ashiko's background is known, outside the fact that she is good at getting the jobs she has been assigned done and, as a bonus, on time. She was a highly suitable candidate to lead the extermination of the kenrei.
