An innocent and shy girl who is introduced in the beginning as Suou's friend.

She mysteriously transforms into a contractor shortly after, changing her into a cold, emotionless person. Her power is controlling a huge swarm of cockroaches; her remuneration is pulling out her hair. She later kills Nikolay (her ex-boyfriend) by commanding the roaches to eat him.

Shion kills her with a sniper rifle when she cornered Suou.
