Ichijo Hotaru
Fifth grade transfer student from Tokyo. With the daily log, she can remember the events of the day pretty quickly, so she likes writing and reading it a fair bit.

Koshigaya Komari
Natsumi's older sister. Eighth grader at Asahigaoka Branch School. If only you didn't have to erase the blackboard on day duty, it wouldn't be so bad...

Miyauchi Renge
First grader, the youngest of the five students at Asahigaoka Branch School. She tried disposable chopsticks and bamboo strips, but toothpicks really hold it together the best.

Koshigaya Natsumi
Seventh grader at Asahigaoka Branch School. Kinda weird that the logbook goes around once every three days, huh?
