A Hanamaru Pool: Hanamaru Kindergarten is opening its pool. Excited about her first visit to a pool with Tsuchida, Anzu hurries off to show him her swimsuit and "knock him out." Anzu is feeling pleased with herself when Tsuchida calls her cute when Yamamoto shows up in her (rather disaster-prone) swimsuit.
A Hanamaru Brother: Tsuchida's younger sister Satsuki comes to visit. However, Tsuchida forgets to leave a house key in his mailbox for Satsuki. When she sees the disheveled state of her brother, the already-angry Satsuki explodes. Satsuki begins to wonder if her hopeless brother is doing a proper job at the kindergarten, so she decides to visit him there.
