The game begins with the player beginning to play an online dungeon-crawling RPG titled "Beyond The Labyrinth". While playing with Pokira, Nerikeshi, and LiLy, the player's group begins to hear a voice calling out for help. Suddenly, the 8-bit game world vanishes behind static, and as a different world appears before them in its place, the players encounter a young girl, the one calling for help before, startling each other. Getting over the shock, the girl explains that she fell into the Labyrinth after leaning too far over the edge; luckily, despite the height she dropped from, she landed on top of a healing point (which acts as a save station in-game), which saved her life. Both the girl and players learn that magic is sealed inside the Labyrinth, and many dangerous creatures who use this power reside here.
