Hogwarts: from the Time of the Big Four

——Good news: I traveled to the magical world ——Bad news: a thousand years too early Ciel travels through the medieval magical world, where there is no Hogwarts, no Wizengamot, and no Azkaban. There were only flaming stakes and dark wizards that Voldemort would call "fuck". And he is being locked up in a dungeon by a dark wizard, and may become a consumable in experiments at any time. "But it doesn't matter. The great four giants of Hogwarts will end this troubled world, and the evil dark wizards will eventually be punished." Until a timid voice sounded behind Ciel. "The Big Four of Hogwarts?" "They must be very powerful, right?" "By the way, my name is Godric Gryffindor. When will the Big Four rescue us?" Looking at the four imp inmates with expectant faces, Ciel fell into silence. "Forget it, the Big Four are unreliable." "You still have to rely on my... System dad!"
