Kyou no 5 no 2 (TV) EP6 - 20th Period 'Observation Diary' / 21st Period 'Sudden Shower' / 22nd Period 'Rock Paper Scissors' / 23rd Period 'Summer Festival'

Yūki suggests Kazumi observe a more dynamic event than flower growth - experimenting with different methods to wake Ryōta from his nap in spite of his earlier warning to do otherwise. After school one day, a game of dodgeball of boys against girls is interrupted by a sudden rainstorm that forces the children to take cover. However, they decide to continue to play; even Kazumi joins in. In the summer heat, Ryōta is challenged to several games of rock-paper-scissors with the penalty of fanning the winner. Ryouta's attempts to defy his constant losing streak land him in hot water with Chika who promptly beats him up for accidentally flipping her skirt. Ryōta, Kōji, and Tsubasa rush to the summer festival but arrive too early. Natsumi, Kazumi, Megumi, Chika, and Yūki arrive shortly thereafter dressed in their yukatas and both the boys and girls began to enjoy the festival together.
