In the year 199X, labyrinths known as "Dungeons" appeared across the world, bringing forth countless monsters from within. Inside these dungeons, modern weapons ceased to function. The world's military forces were on the losing side.

In time of peril, Sirius, a self-proclaimed great sage from another world, emerged to save the world from the brink of destruction. Thanks to the divine blessings of a temple he had established, people awakened to magic and skills, which were only usable within dungeons. Those who wielded these powers became known as "Explorers."

In 2005, through the final operation, an Explorer party succeeded in defeating the Demon King, saving humanity from its crisis. However, one hero remained deep within the dungeon. Yet, the dungeons still persisted across the world.

He was also the boy who had failed to return 20 years ago. <<less
