This BSD × Hogwarts AU takes the Bungou Stray Dogs characters and reimagines them as Hogwarts students in a world where magic, politics, and reputation are just as dangerous as spells and duels, with four houses still shaping students but hidden power dynamics running beneath them. At the center is Victoria Black, a Ravenclaw heir to the British magical royal family, raised under strict control and emotional restraint, arriving at Hogwarts highly polished but internally conflicted, alongside her Slytherin best friend Ophelia Ellis, who helps her navigate social influence while pursuing her own ambitions. The school becomes tense and chaotic with figures like Osamu Dazai, a manipulative Slytherin strategist secretly obsessed with provoking and understanding Chuuya Nakahara, his fiery Gryffindor rival; Fyodor Dostoevsky, a calm Ravenclaw who views people as systems to analyze and control; Paul Verlaine, a detached and dangerous Slytherin who quietly observes more than he speaks; and the intense rivalry between Atsushi Nakajima (Hufflepuff) and Ryunosuke Akutagawa (Gryffindor), who constantly push each other toward growth through conflict. As alliances, crushes, rivalries, and psychological games form between students, Hogwarts becomes less of a school and more of a shifting battlefield of minds and emotions, where every interaction carries hidden meaning and Victoria slowly finds herself at the center of a world where no one is truly simple, and everyone is watching.
