Meiko gradually gets used to life at the manga cafe, going shopping with Oto and brainstorming new menu items with everyone.
Then one day, Kozue Amamiya, Rie's mother and the chairwoman of Amamiya Girls' Academy, visits the shop. Kozue
tells her that the shop will close if things continue like this.
It turns out the shop is running at a huge loss due to Rie's reckless management. Meiko and the others have to quickly start working to improve the business situation, but...?

It's the height of summer, and Meiko and her friends are in high spirits as the manga cafe is doing well with customers.

However, a sudden air conditioner malfunction forced them to close the shop. Rie was disappointed that the business had been going so well, but Kozue tried to cheer her up.

Then, as Meiko and the others are wondering where to stay until their air conditioner is fixed, Kozue suggests their villa in Guam.

Meiko and her friends, along with Michika, suddenly set off for a tropical resort!
