Do You Believe in Ghosts? (Triple S x Reader)

The monsters are real. They roam this land. They terrorize the citizens. No one knows where they came from or how to stop them.
That's what (Y/n) is for. She's immune to all the kinds of magic and possessive spells the monsters possess, and she wants to use that power to find a way to drive them out and save Mobius because the people who would have done that are gone.
But she knows where they are.
Sonic the Hedgehog.
Shadow the Hedgehog.
Silver the Hedgehog.
All of them disappeared when the monsters arrived. Who was going to save them? Without them, the world suffered and surrendered to fear quickly. But (Y/n) has located the missing heroes and plans to pay them a visit.
Boy, is she in for a wild ride.
