If You're Happy, I'm Happy.On the school's roof, Riki finds Komari Kamikita, a clumsy girl from his class who craves snacks and sweets. Riki attempts to recruit Komari for the baseball team, only to realize that she may not be well-suited for baseball. After lunchtime, Riki later finds Rin shirking her classroom blackboard duty to play with several cats, in which the white cat named Lennon has two notes tied to it. The first note says, "There is a secret to this world. If you want to learn it, you must complete all the tasks you are about to receive." The second note says, "This is the first task. Resolve the sanitation issue in the boys' dorm storage room." Riki doubts the sincerity of the notes, but Rin is excited to take on the first task. Rin gathers up Riki, Kyousuke and Masato to clean the storage room. Komari finds them there and agrees to join their baseball team, but they all get to work cleaning the storage room first. On the baseball field, Kyousuke welcomes Komari onto the baseball team despite her complete lack of athletic ability. Soon after, Riki collapses from an attack of narcolepsy, which he has suffered since childhood.
