When Angels Fall
Mobius has a hero. He's faster than sound. The blue hedgehog has a kind heart, though it might not always be obvious. He will do anything for his friends. No one is closer to the hyperactive hero than Miles "Tails" Prower. Sonic and Tails are more than best friends, they're brothers. So when the demon within tries to claw it's way out of Sonic, Tails immediately senses something is up. Will Sonic allow the demon to tear the two apart? Will he be able to keep the darkness contained? How long before something pushes him over the edge?
