Summary[]
. The Peek a Boo crew head to a diving equipment store to buy new gear for their trip. Kohei spots a pair of women's wetsuits that pay homage to a very popular anime, and is elated when Chisa and Aina try them on, even though only he understands the reference. When the crew returns home, Nanaka tells them that they'll have to do more work to make up for the money they spent on new diving gear. The next day, Azusa, Chisa and Aina end up working at the same convention as Iori and Kohei.
