Synopsis
This is Mayu Hama. It's about time for the school festival season! I'm planning to enter a contest for my own clothes, and the blood of the kimono shop's family makes a noise! However, the traditional sewn Buddha, which is a symbol of the school festival, was stolen, and the alumni association who knew it said, "I can't make a donation without the sewn Buddha!" The budget may be insufficient and the school festival may be canceled! Really! Mr. Makoto asked the child to negotiate with the OG chairman, but he seems to say, "I can't negotiate because there is no material for negotiation." Is it okay? Isn't it really canceled?
