Sapphire Fur and Crimson Nights

Sonic grew up with his 2 brothers, with-holding a small secret from them. All adopted, they lived in fun peace, and Sonic enjoyed it. He dared not disturb this bliss with the fact that he was a werehog. He usually says that he was out with his childhood best friend, Amy Rose, but he always goes out on the nights of a full moon to hunt and stay away. Amy Rose was in on the secret, but she understood to play along and never expose him.

One night, Sonic was on his usual full moon escapade when he suddenly got tackled down by another creature, to which he attacked in self-defense. She was a Mobian, but with visible fangs and blood dripping down a claw injury on her wing. She looked fearful but alert and cautious, hissing at Sonic. Suddenly, he saw a handsome Mobian run by, swiping up the female and looking back at Sonic. The daylight burned him, his skin forming small bits of smoke as he began running. Sonic felt obligated to help him.

From then on, Sonic began visiting them, caring for these vampire Mobians, and even falling in love with one of them. Will Tails and Knuckles find out about Sonic's 2 secrets? Will the vampires learn to trust the werehog? Can Shadow fall in love with a mortal?
