A pool of Komeiji Koishi causing trouble for people. The power of being able to become completely invisible to people, as well as her acting on pure unconciousness and thus being unable to do anything but let the intrusive thoughts win means that she can get into quite a lot of trouble. Her elder sister, Komeiji Satori is one of the most frequent victims, as is Hata no Kokoro, referencing Koishi's theft of her mask in Hopeless Masquerade.
