Ep. 2: Iori prepares his room for a mixer while Shinji and Ryujiro prank him with lewd posters.

Iori realizes he has not slept in his new room yet. The residents of Peek a Boo plan a mixer with women from Oumi Women's College. Iori attempts to tidy his room to prove his responsibility to Nanaka. Shinji, Ryujiro, and Kohei decorate the space with lewd posters. This causes awkward moments when Nanaka and Chisa inspect the room. Nanaka forces Iori to sleep in a dilapidated adjacent room. Later, Shinji and Ryujiro take Iori to a local pool to prepare him for deep-sea diving. After witnessing Ryujiro rip off Kohei's bottom, Iori decides to avoid involvement. That night, Nanaka takes Iori to an aquarium at Chisa's request. This experience inspires Iori to consider trying out diving.
