A young man dies from a merciless fever, only to be reincarnated in the World of Genesis—a brutal land of swords, magic, and a god-like System that governs all life.
He is reborn as the lowest of the low: a defenseless caterpillar.
But fate has granted her a monstrous gift. As Kireina, she can consume any creature and steal its powers, skills, and very essence. Using cunning and extraordinary adaptability, she claws her way through a world that wants nothing more than to devour her alive.
Through relentless evolution and sheer willpower, Kireina gathers devoted followers and builds a fearsome monster kingdom from the ground up. In a realm ruled by humans, ancient horrors, and arrogant gods who conspire for her death, she carves out her own destiny.
To those who stand against her: submit… or become her next meal.
