(Kirasaya) (Meariri) Harlequinade

A piece of foolish or silly behaviour.

Midari's stupid choices (again) causes Sayaka and Mary to turn into toddlers.

The Momobami twins have to take care of them and they're not very good at it.

They seek help from many people.

Terano finds herself having to babysit to children. One who cries too much and one who bites people too much.

Midari struggles to find a cure.
