Promotional image for No Future most of the main characters (for the most part) From left to right we have Abbadon (God of Death) Era (God of Future Time) Andrew Perkason (Artist name SIN. Though he can't really make up his mind on what name is cool for him so it changes at least once a year) Hannah and Aeon (God of Past Time)

Death is final and cannot be changed, not even by gods.

The god of death accidentally took the life of Andrew Perkason before it was his time to go, in an attempt to compensate Death asks Era and Aeon, two lesser time gods, to go back in time to warn Andrew of his fate and give him a second chance at living his life so that he may live it with as much fulfillment as possible before his untimely encounter with death.

Andrew must now try to meet his life goals before he dies, while balancing school, family, his social life, a girlfriend and living with two lesser gods who are constantly looking over his shoulder and judging every decision he makes.
