There's a thief (a "Ghost Thief", if you will ), and they're causing paranoia around the city. Shadow is called on to help track them down, but he gets a surprise when he sees that the thief is an old "friend" of his. (Cover picture isn't mine.)

You know how with some ships, there's one that's almost always the uke? Well, not this time! (Sonic, Silver, and Manic are male. Shadow, Mephiles, Scourge, and Fleetway are hermaphrodites) I own nothing from SEGA.
