In a world fractured by conflict and haunted by shadows of the past, Kokushibo—the first Upper Moon demon—meets his end, only to awaken in a new life. Reincarnated as Crimson, a child born into a different family, he carries the memories of a past he cannot escape. Burdened by centuries of guilt yet indifferent to the present, he resigns himself to duty—until an unexpected bond with his newfound family begins to thaw his hardened heart. As he struggles between the weight of his past and the weight of the new life, Crimson must decide whether he will remain shackled to his former sins or embrace the possibility of peace.

If human life could continue to grow stronger indefinitely, reaching infinite heights, then one day it might connect with the heavens!

In the year 3000, humanity was forced to leave the earth when a sudden mutation caused more than 70% of the planet's population to mutate either into zombies, werewolves or vampires. The humans put up a fight but didn't have a chance against the united front of the monsters and they were forced to leave. At least those who were rich and lucky enough to leave.

A century later, the chaos on earth had calmed down but the humans who were left behind were treated like slaves and were forced to join one of the three factions: The Undead, The Cold Ones or The Lycans when they turned 16.

It was a similar story for Ashton, who was one week away from being turned into one of the monsters as it was his 16th birthday. He decided to run away from his fate and join the secret resistance to battle against the monsters.

However, his plans came to a standstill, when a series of misfortunes leads him to be bitten by a Zombie, a Vampire and a werewolf before either of his powers could manifest.

He ended up receiving all of their powers, but at the cost of his humanity. Yet, he wasn't willing to let his humanity die. No matter the cost.

Will he be able to live his life, or was it already too late? Which faction will he join? Will he be able to find the secret behind the mutation?

There were too many questions, and only one way to find the answers: follow Ashton's journey as he fights back to retain his humanity.

Having lived a normal life all his life and died without being able to fulfill his desire and when he’s given a task by a god, watch how he takes the protagonists girls while making it hard for the hero.
