Hime-chan and Pokota cannot sleep because of the warmth of the night (it's summer), so they go to the window and open it, and spot a strange light moving quickly in the sky. The next day at school, Icchan is sleepy, as she didn't sleep much the previous night because she also saw the UFO. Then Daichi and Tetsu come by and invite the three girls to go camping where they'll see plenty of shooting stars far from the city lights. They beg Gori-sensei, who also saw the UFO and used to belong to a UFO club at school, to escort them.
