People born with sword abilities — Mansaengjong — are the world's hunters. One day, all of them are suddenly transported to Naraka, a monster-infested realm with no way out. Seowoon, once a top-ranked hunter, loses all his combat abilities upon arrival. Instead, he gains a strange new power: detecting where monsters will emerge. Useless for fighting — but not for surviving. Cahaya, a powerful hunter, sees his value immediately. "Cha Seowoon, from now on, be my mutant searcher?" What starts as a survival arrangement slowly becomes something neither of them expected. Why did I push you away?.. An award-winning story about two hunters, an impossible world, and feelings that refuse to stay buried.
