A chaotic class full of dialect-speaking girls!?

Nestled amidst the sea and mountains, in a nature-rich provincial city—stands the ultra-prestigious, all-boarding school for young ladies, "Musubi Girls' Academy". This sanctuary, boasting a Western-style campus, state-of-the-art research facilities, and a vast greenhouse garden replicating the climates of Japan, is about to welcome its first and only male student.

A special class formed by gathering one student from each of the 47 prefectures, each representing their region with outstanding talent and a strong personality. Standard Japanese is considered unrefined—in a world where dialect is status, every day is a chaotic yet endearing storm of cultural exchange!
