Once every 100 years, the cursed labyrinth "Naraku" corrodes the world. Helmut, the great monster who reigns at its deepest reaches the dungeon, receives news that the king has been imprisoned. The kingdom is engulfed in deep despair, and everyone senses its end. Meanwhile, one man quietly arrives at the Guild Tavern. His name is Allen. To carve his own existence and resist the despair that has overflowed the world, he ventures into the depths of "Naraku." This is the story of a new adventurer woven in "Naraku of Beginnings."
