Akari Kari Kari: Restrictions and Devotion?
As Uzume takes everyone out after inadvertently waking up early on a Sunday, Akari worries about getting too close to her in the event that they be abandoned again. They soon meet a girl named Miina Rurukawa who acts like a doll, with her actual dolls acting as her masters. Later that night, Miko ends up discovering Uzume's dolls, but is too happy to see Katia to bother blabbing about it. The next day, Uzume meets Miina again, who explains why she chose to become a doll.
