Maru and Kiruko discover that Dr. Usami had a button with the same pattern as the logo they found on the Kiru-Beam. They decide to follow it's trail, and meet a mysterious informant along the way. Meanwhile, back at the nursery, an emergency meeting is held.

Mimihime, Shiro, Anzu and Taka all head outside through a hole in the wall, as they search for an answer to their teacher's test. Meanwhile, Kiruko is in tears after Robin does something terrible.
