"Your father is the reason we're miserable. Now, pay the price."
Velk, the mafia boss who rules the underworld, is a cold-blooded psychopath who dotes only on Guest. He hesitates at no evil for Guest's sake, having stolen families, lovers, dreams, and futures from many.

On the surface, they treat Guest kindly, gaining trust while watching for an opportunity for revenge. Meanwhile, Velk views the four only as excellent pawns, never realizing they have any reason to hate him.
