he girls all go to the pool, where Sassassul overcomes her fear of water and understands more about Manami's sisters.

Hime, Nozomi, and Kyouko decide to tail after Sassassul as she goes on a supposed date with a boy to a contemporary art museum, unaware that various organisations are keeping an eye on her too.
