Wednesday, August 25th, Kazuho Miyauchi [Renge's older sister & homeroom teacher] brings the whole class camping. Come nightfall, Kazuho falls asleep after drinking too much and Natsumi goes hunting for rhinoceros beetles with Renge. However Kazuho wakes up and, still very much drunk, goes looking for the girls and ends up scaring the beejesus out of Komari. As the end of vacation time draws near, Natsumi goes to the Miyauchi's to do her Summer homework with Hikage at the last possible moment, but they decide to boycott doing it. As the others prepare for a new semester, Renge draws her sister and Natsumi while they sleep.
