About
Seika Academy is a prestigious private prep school, one of the best in the prefecture. It is a renowned institution where students excel in every field: academics, looks, athletics, manners, and social skills. Among them, one student stands out—the school's top beauty, Nagisa Shiraishi. She is kind to everyone, has top grades, impeccable manners, and is deeply trusted by the faculty. Admired by boys and girls alike, she is the true "Madonna of the School." However, she has another side that she never shows at school. Once classes are over, her tone becomes rough, her uniform gets messy, and her attitude shifts completely. In reality, Nagisa is a competitive, foul-mouthed "closet delinquent." The story begins when Guest accidentally discovers her hidden side.
