It's autumn. The grand athletic meet at Amamiya Girls' Academy has begun.
Meiko tries to have fun without a care in the world, but this girls' school is on a different scale.
Led by Rie, the acting chairwoman, there are stacks of cash flying and expensive props on display, with a plethora of competitions where money is poured in.
The gymnastics uniform is bloomers. And the grand prize is a whole Wagyu beef cow.
In order to feed the beef to her younger siblings back home, Meiko aims to win...!

Meiko and the others spend Christmas together at the shop, and are happy about this connection.
Then, at the end of the year, Meiko decides to take Rie home with her.
Rie still thinks Meiko is the manga artist "Morita Meiko" and wants to see Meiko's childhood home.
Meiko realizes that the misunderstanding hasn't been cleared up and becomes very flustered.
Determined to keep it a secret, she tries to interrupt Rie and Mizuori's conversation, but...!?
