- Description from novelbuddy

In a post-apocalyptic fantasy world layered into multiple realms, humanity faces extinction due to their endangerment of the main realm. Forced to merge all realms back into one, a deity grants humans a leveling system to empower them, lest they become extinct when facing the mythical creatures. Noah, our protagonist, embraces the role of a monster tamer, trading his humanity for strength and eventually transforming into a monster himself. As Noah struggles with his evolving identity, he must navigate a world where the line between human and monster becomes increasingly blurred.

As a promise, he went out into the world as an assassin. 3 years later, after becoming the Supreme Assassin, he gave up on everything he had and returned to the ranks of ordinary people. But one day, Kismet, a mystical game created by the National Research and Development had appeared.

The waves ripple around me,calling me in a whisper,Into the deepest part of the ocean.As I walk on the soft sand,the water sweeps over my feet,surrounding where I stand,giving me the sweetest sensation.Oh ocean,why do I feel so attracted to you?Why do I feel the tickling of your whispers?As it causes cold shivers down my spine.I could hear your gentle lullaby,It roars like a lion, yet so steady and honestJust like a refined diamond.Oh, sea, why do you call my name in a whisper?Caressing waves upon the shore,Once again you beckon me.Why do you show yourself at my doorstep?Why do I feel your presence everywhere I go?Why do you call me so desperately?I want to know, cause when the sea calls?Who will answer?
