ヤマトナデシコ七変化 [Yamato Nadeshiko Shichi Henge]

A 36-volume romantic comedy from Kōdansha (2000–2015), Yamato Nadeshiko Shichi Henge follows a beautiful but rough-mannered girl who must master the art of being a "proper lady" to inherit her family's mansion. The series, best known for the work of creator Tomoko Hayakawa, blends slapstick humor with genuine character growth, making it a standout shojo manga of its era. Its enduring popularity stems from its clever subversion of the classic "makeover" premise and the warm, chaotic chemistry of its central cast.
