When Two Worlds Collide [A Creepypasta and BNHA Crossover]

A considerable rift appeared between the two opposing sides during an ongoing war between supernatural beings in a world filled with nothing but eternal darkness. The rift grows more extensive every second, eating every matter of existence close to its radius. As the two sides try to get a sense of what just appeared before them, they find themselves being swallowed whole and waking up in a different place in a different world from theirs.

Will they be able to return home to finish the war before it is too late? Or will they stay and be the ones to bring the Age of Darkness they once brought to their world, to the new world they found themselves in?
