Snake Eyes (Attack on Titan Eren x PreTrans!Armin Harry Potter crossover)

Eren Jaeger lives with his father in a tiny apartment in London, where he's been since his mother left them nearly two years before. But one fateful day, Eren receives a letter promising a magical world at his fingers. He is suddenly thrust into a world of magic, surprise, and rivalry from the second the sorting hat is placed on his head. And then there is the shy girl who sweeps Eren of his feet- she's smart, kind, and has a deep secret. Armynia Arlert is different from the rest of the kids at Hogwarts. Unlike them, she isn't sure if she belongs with a dress or a tuxedo.
(Note: I do not own any of the characters or universes, and I did mess around with the story a bit. It also contains some boyxboy parings, and some girlxgirl. If you don't like it, don't read it. It also has transsexual kids. The artwork on the cover is not mine, but the final cover is.)
