CHANGE THE WORLD -BLOODTHIRSTY KILLER FROM TODAY

Saito Yuichi has always viewed himself as a social outcast—a self-proclaimed reject drifting through life with no real purpose or hope for change. That all comes to a shattering halt when a freak accident swaps his consciousness with that of Mitsumune Sakutaro, a decorated and elite police officer. Awakening in a stranger's body—lean, authoritative, and wearing a badge of immense trust—Yuichi finds his own mind intact but his reflection completely alien. At first, the situation feels like a miracle; he imagines trading his miserable existence for the glamour of high-stakes detective work, solving crimes and commanding respect in a world that once ignored him. But the thrill of his new life quickly curdles into something far more sinister. As Yuichi settles into Mitsumune's daily routine, he starts uncovering unsettling anomalies—gaps in memory that don't align with his own, and a chilling, visceral instinct that flares unbidden in moments of tension. The body he now pilots is not a simple tool of justice; it carries a hidden history stained with violence and darkness, secrets that his predecessor buried deep. Every case he investigates and every shadow he follows seems to pull him closer to a terrifying truth: his new vessel was never just a cop's shell. It belongs to something far more dangerous, and if Yuichi cannot unravel the mystery in time, he may find himself trapped as the very monster he never wanted to become.
