Kirara, a fashionable high school gal from modern Japan, suddenly wakes up in another world… as Chelsea, a noble daughter known as the “useless disgrace of her family.” She has no idea how to navigate noble society, let alone any of the “isekai rules” she was supposed to know. Worse, her scheming little sister Jennifer has turned everyone against her. But Chelsea isn’t one to go down without a fight. Armed with stubborn determination and natural charm, she seeks out a famously strict tutor and throws herself into mastering etiquette, politics, and high society. Her transformation doesn’t go unnoticed—soon, her reputation is soaring, and even Crown Prince Valentino starts paying her extra attention... maybe a little too much attention!? From “total failure” to “totally adored”! This gyaru-turned-lady is about to steal the show—and possibly the prince’s heart, too.
