¡Zero!

In a world shattered by dimensional tears known as Rifts, chaos spills into reality. From these cracks emerge twisted creatures—Riftborn—and with them, power. Some humans mutate into Risioms, gaining extraordinary abilities at the cost of humanity. Others, like Jae-hyun, are left to fight with grit, knowledge, and the will to survive. At just sixteen, Jae-hyun is a military medic. He stitches together wounds, searches for the fallen, and carries even those he can no longer save. In a war between human and riftborn's, where child soldiers are cheaper than bullets, his hands are rarely clean—but his heart still hopes. But hope is fragile. During a mission beyond the front lines, Jae-hyun is gravely wounded by a Riftborn—until something ancient finds him. It offers him survival. Power. Purpose. The price? Souls. Human, monster, innocent—it doesn’t matter. As the world burns and the line between savior and reaper begins to blur, Jae-hyun must decide: will he remain a healer in a world of monsters, or become something far worse to stop them?
