Adelaide

The fifteen-year-old firstborn of Viscount Liner's family, Adelaide became the protagonist Mitsuha's first significant client in this other world, just as Adelaide was preparing for her debut social ball. Drawing upon knowledge from modern Earth—including cosmetics, gown design, and party planning—Mitsuha transformed the event into a legendary celebration that left noble society across the entire kingdom in awe. From that moment on, Adelaide became Mitsuha's most steadfast ally and close friend within aristocratic circles.
