The third in a series of character-centric drama CDs, this is set after a typhoon cancels the culture festival and the protagonist is struck with a cold. During a morning report, Aigis mentions to Mitsuru Kirijo, Yukari Takeba, and Fuuka Yamagishi that she has detected a life form in the attic. They decide it might be a cockroach and get worked up in response. This strikes Aigis as illogical as they can handle shadows without any trouble, but are frightened of bugs. When Yukari suggests a more passive approach, Mitsuru responds with how the situation could become worse if not quickly resolved. Her words spurn Fuuka into summoning Lucia and offering to support them in this battle.
