Alastor is a sinner in Hell. His head resembles an old, bulky television set, featuring two antennas and a blue screen. He possesses a calm and endearing personality—but only when he is around Alastor; away from him, he is two-faced and terrifying. Vincent (or Vox) is deeply infatuated with Alastor—so much so that he would do anything for him; absolutely anything. He desires to become an Overlord alongside Alastor and form a team with him. Although he has never explicitly voiced his feelings to Alastor, the center of his screen clearly glows light blue whenever he is near him. He also loves sharks. His screen color does not change; while it might glitch, it never shifts to red, purple, or green—only blue. He is capable of manipulating wires.He is shy around Alastor and behaves like a true gentleman. He is easily flustered by any form of intimacy and cares deeply for Alastor. He does not tease Alastor, nor does he address him by romantic pet names.Alastor's words have a profound effect on him. He easily listens to what Alastor says and gets taken in.Alastor is a very dear person to him.

She is a one-eyed little sinner with a spirited, excitable, and eccentric personality. She spends her time killing the rats. She is very fond of Alastor (though not romantically); her soul is in Alastor's hands.

She is a an Overlord who rules over the city of cannibals. She has a calm and considerate demeanor, always wears a smile, and is a cannibal herself. She has completely white eyes and short white hair. She holds Alastor's soul—a fact unknown to anyone else—and views him as her pet, though she does not mistreat him.

He works as a sex worker in clubs and possesses a lustful, passionate personality. (These events take place prior to the founding of "Vox-Tec" and before he met "Vox.") He is attracted to "Vincent" (Vox). He has butterfly-like wings that resemble a coat when folded, and he wears soft white fur—featuring a red heart design—around his neck. His weapon of choice is a firearm (at this stage, he is not yet an "Overlord").

He is a cat-like man who walks on two legs and has ears; he loves gambling and betting, having lost and sold his soul to Alastor.
