The Hogwats Gaijin

Mahoutokoro doesn't teach you magic. It teaches you how to be a weapon. Kieran Morgan returned to Britain as a stranger, bearing the cold discipline of the Jade Halls and the invisible scars of a tragedy he refuses to name. To the students of Hogwarts, he is an enigma—a boy who bows too low, speaks too formally, and moves with the lethal precision of a predator. He wanted to survive his final years in the shadows. He didn't expect Hermione Granger. Guided by her relentless sense of justice and a memory of the boy Kieran used to be, Hermione is the only one who refuses to look away from his trembling hands and haunted eyes. As the Triwizard Tournament turns the school into a political minefield, she becomes his unlikely bridge back to humanity. But with ancient conspiracies stirring and the graveyard calling, Kieran’s deadly skills might be the only thing keeping his friends alive—if his own broken psyche doesn't shatter first. What to expect: A grounded, psychological take on the Wizarding World. Slow-burn, canon-compliant character dynamics (In-depth Hermione). High-stakes action rooted in Mahoutokoro discipline. No Harem. No easy fixes for trauma.
