Chronos Ruler Vol. 1

Humans are always wishing they could turn back time, but they do more harm than good. In this world, each wish spawns a Horologue – a time-eating demon with an insatiable appetite. Luckily, a secret group called the “Chronos Rulers” use their special powers to battle the demons and keep the world balanced.
Victor Putin is one such Chronos Ruler, a jovial widower who ages in reverse thanks to a Horologue named Aiks. With the responsibility of a son in one hand and his job in the other, will Victor be able to stop Aiks before he reverts to nothingness?
