そして少女は狂いだした ―終末月夜抄― (Soshite Shoujo wa Kurui Dashita -Shuumatsu Tsukiyo Shou-)

Background
Nemesis Sudou (GUMI) is locked inside a house in the woods. While waiting for her mother to return, she hears the whispering voices of a pair of twins telling her she's been abandoned. She denies it, saying her mother will come back eventually. However a long times passes and Nemesis remains in the abandoned house and begins to go mad and wonders if her mother locked her up on purpouse to make her insane.

This song is an album exclusive released on Akuno-P's The Muzzle of Nemesis album.
