Trait Hoarder

As a top-tier free-to-play ranker in the unforgiving mobile game "Arcane Seoul," Kim Joonsoo never expected to wake up trapped inside the game itself—stuck as Warrior Kim, a weak baseline tutorial character. Thrown into a ruthless world where death is permanent, his only advantages are his master-level game knowledge and the character's unique, hidden power: the ability to endlessly swap and hoard traits. With the odds stacked heavily against him, Joonsoo must weaponize his strategic expertise and adapt on the fly to conquer a system designed to break him.
