Ao prepares to go to a fireworks festival but is met with opposition from Jinrai, who believes she shouldn't wear underwear under her kimono. Although the resulting commotion leads Ao to miss the festival, she gets to watch them on the roof with the F.A. Girls. Later, as Ao attempts to finish her summer homework at the last minute, the F.A. Girls are tasked with fetching her notebook from school at night, providing Baselord and the Materia Sisters with an opportunity to scare them by pretending to be ghosts. However, the girls soon become the target of a haunted pair of nippers, which manages to fulfil its goal by snipping a leftover fragment off of Gourai's armor.

果たして花火は見れるのか！？

轟雷、スティレット、迅雷、アーキテクトは夜の学校へと向かう。
そこに待っていたのは世にも恐ろしい怪奇現象の嵐で――
