You're not here to guess. Diablo, Testarossa, Veyron, Esprit, Ultima, Carrera. Those are all names of super cars from which author took the name. Also, Diablo is not daemon of all daemons, he is one of the oldest like Guy. Guy could be a daemon of all daemons since he first achieved Demon Lord title and was granted a task to be a Demon Lord and challenge mankind from Veldanava.
