Gekka Midarezaki 乱崎月香

The 'youngest daughter' of the Midarezaki family. She is a jellyfish; however, she is able to do things that are unusual for a normal jellyfish such as writing letters or changing her body's color according to her feelings. The sub-director of Supernatural Phenomenon Treatment Bureau's operation department went fishing, caught her and DNA-tested her for fun, and it turned out that a mere jellyfish actually has Enka's DNA, so she became a member of 'Peacefule Family Operation'. Her real name and exact age is unknown. Occasionally a dark-haired female with crescent-shaped insignia, dressed in a manner of Heian period, appears in the book, and it is believed by some family members that she is Gekka.
