[Machine Translation] The secret of leveling up that only I know - the quest story of the weakest hunter! More than ten years ago, after the "Gate", a passageway connecting another dimension and this world, awakened people called "hunters" appeared. Hunters are those who defeat monsters lurking in the dungeons inside the Gate and earn a reward for their work. Shun Mizushino, an E-class hunter who is called the weakest weapon of mankind, was reluctantly continuing to be a hunter in order to earn money for his mother's medical treatment. One day, however, he encounters a dungeon of high difficulty and is given a special ability just before his death. Only Shun knows the secret of how to level up...how far will his level up go?
