Tiara is introduced to three sisters from Yamato who also go to Flora Girls' Academy: Kaede, Nadeshiko, and Tsubaki. Supposedly, they get along pretty well, but there seems to be some tension between Kaede and Nadeshiko.

The girls go look for Maryberry, who has disappeared. Meanwhile, some of the girls may have figured out the cause of the supernatural phenomena they've been sent to investigate.
