Twenty-five-year-old Kazuki Hayato was the laughingstock of the Hunter Association an E-rank hunter who couldn't even kill a single goblin without nearly dying. In a world where mysterious Gates spawned deadly monsters and Hunters gained powers to fight them, Kazuki was the weakest of the weak. After a humiliating failure during a routine dungeon raid, he was kicked from his guild and left to die by his own party members.

But everything changed when a mysterious System awakened within him.

Unlike other Hunters who were born with their abilities, Kazuki discovered he could level up infinitely through completing quests and defeating monsters. What started as simple push-ups and basic exercises soon evolved into life-threatening challenges that pushed him beyond human limits. With each level gained, Kazuki grew stronger, faster, and deadlier.
