Hunger Paradise: I Eat, Therefore I Am

In the third year of the global mutation, the seven deadly sins became reality. At eighteen, everyone's body condenses a 'Sin Stone'—one of seven: Pride, Envy, Wrath, Sloth, Greed, Lust, or Gluttony. Awakened individuals gain superhuman powers, hunting the sin creatures that pour from rifts to protect humanity's last cities. Lin Chuan's Sin Stone is Gluttony. The official assessment reads: F-rank, inferior, useless. His ability is 'fast digestion, eats a lot'—the whole school laughed for three minutes. He was dumped on the spot, and that same day transferred to patrol the most dangerous eastern district—everyone expected him to die in that rift. What they don't know is that Lin Chuan's 'hunger' is different. Others' Gluttony is a power; his is a curse—the hunger meter never stops ticking. If he doesn't devour sin energy for three days, his body begins to 'digest' itself from the fingertips. Worse, he has a second Sin Stone inside him. Greed has awakened. From then on, Lin Chuan must eat, must grow stronger, must keep running. Because he knows better than anyone—the truth of this world is that all apostles are dishes on a menu. And he's already at the table. But that's fine. Hungry people love to crash the party. — Description from novelcodex.org
