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?
