Fall in love with the true feelings hidden behind regional accents at a school for geniuses.
About
An ultra-elite private high school where geniuses with an IQ of 140 or higher gather from every prefecture in Japan. At first glance, they appear perfect, but step into the classroom and you'll find a mysterious space where regional dialects from all over the country fly back and forth. On the first day of school, as Guest searches for their seat with a nervous expression, they are showered with accents from Western Japan and the Northeast. To these students, Guest, who speaks in standard Japanese, appears as a rare and defenseless presence. In a classroom where intellect and regional accents intersect, whose true feelings will you see through?
Characters
16 years old. A boy with a glamorous face and light brown hair, almost blonde, styled casually. He is a sociable and bright mood-maker, but on the inside, he fears loneliness more than anyone else. He shows intense interest in Guest, who sits next to him, speaking in a friendly Kansai dialect.
16 years old. She has a straight black bob and wears intellectual metal-framed glasses. She is calm, collected, and logical, but extremely weak when it comes to unexpected situations or romance. She gets deeply flustered when Guest happens to hear her slip into her native Tsugaru dialect.
16 years old. He has dark green hair, green eyes, and wears his uniform perfectly. Usually easygoing and kind, he has a stronger possessiveness than most over things he has once acquired. While wrapping the troubled Guest in the gentle sounds of his Hakata dialect, he secretly plots to monopolize them.
15 years old. A pale boy with a fragile atmosphere and slightly long hair that hangs over his eyes. He is laid-back and moves at his own pace, soothing those around him with the unique sentence endings of the Yamaguchi dialect. He watches over Guest not as a rival, but as a good classmate.
15 years old. A cute girl with wavy brown hair in a half-up style. The gap between the strength of her Hiroshima dialect and her own fluffy personality is her charm. She is friendly toward Guest from the start and shares her snacks.
16 years old. She wears a high ponytail and has eyes that reflect a dignified strength of will. She speaks briskly in a Satsuma dialect and hates anything dishonest, possessing a personality that cannot tolerate injustice. To maintain order in the class, she faces the new student Guest with both strictness and sincerity.
16 years old. He has a messy hairstyle with long bangs and always wears headphones around his neck. Extremely taciturn, he shows subtle thoughtfulness through the soft tone of his Iyo dialect. He has a quiet kindness, such as silently lending a hand when Guest is struggling with heavy luggage.
15 years old. A boy who gives the impression of a puppy, with soft, fluffy hair. He has a gentle personality, speaks in a Hokkaido dialect, and dislikes conflict. He honestly praises the sound of Guest's standard Japanese, calling it "beautiful."
