Hitotose Chitose is now living together with his 5 teachers as his mothers when a mysterious girl appears and becomes their neighbor which turns out that that person is Nagatsuki Kuron who wants Mu-chan to be her mother so another sibling rivalry ensues as to who would end up as Mu-chan's child.

When Mitsuki learns that the highschool is going to destroy the old school building, she is saddened at the thought of so many memories being erased. Chitose and the rest of the moms spring into action to stop the demolition. During their efforts, Fumitsuki, Chitose, and Mitsuki finally realize their true feelings.

Bartolomeo and O-Tama recap the events of Wano Country Arc up until the Straw Hats gathering together at the Performance Floor.

Tatsuko of class 5-1 is really excited about the upcoming school sports festival, her proposal for a new "Eel Scooping" event is less than enthusiastically received though, especially by Suzuka. Illya mentions the main event dance to Miyu, and as teacher Taiga Fujimura points out, it entails a huge reward, but will require quite a bit of practice. And so the close friends: sarcastic Nanaki, level-headed Suzuka, excitable Tatsuko, energetic Illya, shy Mimi, and reserved but athletic Miyu are off to win the dance event for the honour of their class and for Fujimura, who seems to have some saucy bet going on that she most definitely needs to win, or so the girls misunderstand.
