Global Mutation: The Hunger System

The world didn't end with a bang; it ended with a notification. When the “System” initialized, humanity turned into monsters. Ren, a starving college student trapped in a cafeteria, awakens the only F-Rank skill deemed useless by the global rankings: [Binge Eater]. While others summon fireballs or swing holy swords, Ren has to do something disgusting to survive: he has to eat the monsters. But when he takes his first bite of a mutated rat, the System pings. [Genetic Sequence Extracted. Agility +5. Skill Acquired: Shadow Step.] Ren realizes the truth. He isn't the prey. The apocalypse is just an all-you-can-eat buffet. And he’s starving.
