Koshigaya Natsumi: Seventh grader at Asahigaoka Branch School. If she found the last ice cream treat, then it's hers. That's a Natsumi-ism. Koshigaya Komari: Eighth grader at Asahigaoka Branch School. She really wants some ice cream, but she's the oneesan so she's being strong. But she does want some... but she's strong... Miyauchi Renge: First grader, the youngest of the five students at Asahigaoka Branch School. The question of how she can make Natsun's ice cream her own is the puzzle of the century for Ren-chon now. Ichijo Hotaru: Fifth grade transfer student from Tokyo. She seems like she's cool as can be, but she wants to eat that ice cream more than anyone else. But she can't say that. She really can't say that.
