The Crimson Oni Mask: The System Blood
Josuke Hachimizu, a 22-year-old young man, thought his personal hell had ended when he left the military. After six years trying to forget the war, all he wanted was a normal life… but fate had other plans. Without warning, he is torn from his world and thrown into an unknown land by the will of the enigmatic God of Souls.
There, he awakens with a broken system: the Blood System, a flawed power that prevents him from leveling up like a normal adventurer. Abandoned and cast into the Seventh Underworld—a place even demons fear to tread—Josuke is left to die.
For ten years, he survives fueled by pure rage and hunger, consuming the blood of all kinds of infernal creatures, slowly evolving into something far beyond human.
But when he finally escapes, he does not return to the world he once knew. Instead, he's thrown into a realm of heroes, guilds, divided kingdoms, ancient prophecies, abyssal continents, and countless dimensional dungeons… where nearly everyone sees him as a threat. And worst of all, the God of Souls still watches him, with twisted, hidden intentions.
With no allies, no clear path, and a system that forces him to drink the blood of his enemies to grow and keep his humanity, Josuke Hachimizu must fight not just to survive… but to shatter the will of those who treat his life like a pawn in the cosmic game.
What would you do… if your only way forward was to unleash the monster within?
