My Fools' Gate (HP X Marvel Au)

A reincarnated man who somehow found himself in the dangerous world of Marvel. To make matters worse, a few years later he receives a letter informing him that he has been accepted to Hogwarts School of Witchcraft and Wizardry... "Harry Potter and Marvel?" I nod to myself, contemplating the bizarre combination of worlds I found myself in. "I see, so if I bring more eldritch beings into this universe, "it should be fine, right?" Since it's already dangerously chaotic, why not up the ante? What could possibly go wrong? After all, I already possess truth in my soul, an omnipotent being observing me. They respectfully and intimately call me "the lackey of the Demon God," and I harness the power of interdimensional beings to carve out a good life for myself in this dangerous universe. HP and Marvel AU - Hogwarts starts at 13 - Fem Harry.
