A refreshing, peerless tale where a commoner from the countryside destroys all common sense! The "Labyrinth (Dungeon)" is a giant tower that keeps spawning monsters. Eto, a boy from the countryside who is a Healer, decides to take on the challenge of conquering the labyrinth on the advice of the master who trained him. However, in society, healing magic is considered inferior to recovery items because it requires a massive amount of mana. Meanwhile, Eto, possessing off-the-charts mana, ignores the bad reputation, keeps healing everything, and even fights on the front lines himself――. Through his unconventional fighting style, he shatters the values of the explorers. Eto, who conquers the labyrinth at an impossible speed, eventually rises to become the strongest existence whose name is known across the entire continent――.
