Akki

Mysterious child who appeared in Kamisu-66 in July of year 237.

She is Maria and Mamoru's daughter, but was raised by the queerats.

She does not experience death feedback after killing humans. The reason why was because she believed that she was a queerat; thus, her death feedback would only initiate upon killing a queerat.

In the end she was killed via death feedback by killing Kiroumaru, who was disguised as a human.
