Labyrinth City Orario—A city located on the surface of a massive underground labyrinth known as the “Dungeon”.

In this city, a young aspiring adventurer, together with his tiny goddess and friends he has made, has escaped death several times and “ranked up” at an unprecedented rate.

One day, he receives a letter—an invitation to an expedition to an unexplored level within the Dungeon. Along with his friends, the young adventurer takes a step forward, into uncharted territory.

This is the “Familia Myth” recorded by a young man and his goddess.
