It's the night before the meteor shower, and Aika and her friends are practicing by going outside to watch it. Aika asks her friend, rub, if they should invite the other two girls to go out and watch the meteors, since one of them would be dangerous and the other would be loud and annoying. She's sorry that they've waited so long, but Aika says that there are lots of cities in the area, so they can go there at night. They decide to go to the roof of a nearby building, where there's no place for them to hide. They climb up to the top, and they watch the streak of meteors streaking across the sky. It turns out that the streak is caused by the atmosphere's friction with the meteor, which makes the meteor burn up and become a meteorite.
