Remnant never knew what true horror was until demons more terrifying than the Grimm arrived, seeking to conquer a world they think belongs to them. Nor the limits a warrior stripped of his humanity would push himself, and others, to exterminate the Slaves of Doom and their mortal allies. His path of perpetual torment continues and this time he will no longer be walking it alone...

Of the long list of those that were deserving of a second chance, Valen did not count himself amongst their number. Yet here he was. Awakening from what he had intended to be his last stand against the forces of Hell, the former commander of the Night Sentinels finds himself in a relatively peaceful land, but one that had monsters of its own.

A Huntsman, a thief, a soldier, and a slayer. This is Team JRHD(Jarhead): four of the most skilled, yet completely crazy and brutal fighters in all of Remnant, and beyond. Though they each hide a dark past, some darker than others, they will have to eventually come together to stop a dark threat looming on the horizon, finding amazing and powerful friends along the way.

The Doom Slayer has managed to kill none other than the devil himself, the Dark Lord Davoth. But now a new world, a new set of challenges, awaits him. Follow along, as he wakes up in Remnant, learns to fit in and play by its rules, then rise to power, to save Remnant, make friends, to kill Grimm, and as always, rip and tear until it is done.

In the midst of chaos the brutal keeper of all beings step foot onto the frantic mayhem that is Beacon. In desperate times of need, a god amongst men are needed to keep balance and cleanse sin. The arrival of the Slayer is noticed by all and he gathers unwanted attention and the boots he walks in will crush the skulls of every entity who dares to disrupt his path to eliminate DOOM.

Against all the evil Salem can conjure, all the wickedness that mankind can produce, I send unto them only you. Rip and Tear until it is done, Slayer, for it is your destiny to slay those who ended our legacy.

The Doom Slayer has slain the Dark Lord. And with his journey done, he is forced to stay into an eternal slumber, until a new evil arises. The Father has failed with his first creation, there was nobody to make balance with Davoth. So now, he creates the Gods of Light and Darkness, the Brother Gods. But when evil re-awakens known as the Grimm, the Slayer must team up with children.
