In the world of Nihilon, every living being is bound by the Level–XP–Skill system, which determines their strength and status. However, among the star-studded adventurers, one mysterious figure emerges, Kai Ardent, an orphaned teenager from Crestfall village who begins his journey as a Pure Level 0 completely devoid of a single Status Point.

The Story opens with Kai joining the Ashen Wings Guild, ridiculed by his fellow apprentices who belittled him. In an expedition to the Skelgard Caverns Dungeon, he encounters his first D-rank monster, the "Rainbow Insect" without any skills. 

However, through his steely will and the Level 0-specific "Blank Point," Kai creates a wave of pure emptiness that destroys enemies, drawing the awe of his rival Luna Selene, the ice mage of the Moonlight Covenant, and earning the respect of his hard-hearted mentor, Ragnar Blackthorn.

As his Blank Points increase, Kai learns how to allocate his free points in Combat, Arcane, and Support, overcoming dangerous traps and minor conflicts between guilds. As word of the “Pure Level Zero” spreads, the shadow of Archon Magnus, an ambitious S-Rank adventurer, begins to lurk. He sees Kai’s potential as a weapon to shake up the Guild Council’s order and establish the supremacy of the "Level Supreme."

In each dungeon, Kai faces not only monsters, but also moral challenges: should he maintain the purity of his Blank Point or trade it for instant power? His friendship with Luna develops, from rival to ally, while Ragnar’s role as mentor reveals his past wounds and ignites Kai’s resolve.
