Hino Akiharu was an orphan who lived with his uncles' family after losing his parents in elementary school. He discovered a new school called Hakureiryou Gakuin, which had been rebuilt from an elite girls' school and decided to take the entrance exam for it. Despite having a sinister appearance, he managed to enter the House Management Department, where he aimed to become a butler. Akiharu has a scar on his right eyebrow, bristled-up hair, and three piercings in his ears, giving him a typical bad boy look.
At Hakureiryou Gakuin, he encountered Saikyou Tomomi, who had a two-faced personality and traumatized him since childhood. Another girl named Cernia Iori FlameHeart also pursued him because of his looks and called him suspicious. However, Akiharu gradually found his footing at the school and improved his relationships with the girls.
