The earth sciences club girls are preparing for their cultural festival. Sakura and Ino, the geology club girls, are conducting a real boring survey on the schoolyard. Meanwhile, Mira, Ao, and Monroe, the astronomy club girls, are working hard to produce a replica of the solar system at Mira's home. Then the day of the festival finally arrives.

With Suzu's help the earth sciences club's geocafe is open for business and all the club members are wearing maid outfits.
