Mimic Awakening

A young man is mysteriously killed in his sleep and wakes up in a world filled with magic, monsters, and gods. But instead of becoming a legendary hero, he's reborn as a mimic—one of the weakest monsters living deep inside a dungeon.

Fortunately, he possesses a rare Awakened Ability that lets him absorb magic crystals and gain the powers and forms of anything he devours. As he fights his way through the dungeon, he grows stronger with every battle and soon encounters a beautiful and powerful mage who changes the course of his journey.

What he doesn't know is that his reincarnation was never meant to happen. His arrival has already begun to change the world's timeline, setting off events that could reshape the fate of everyone.
