The Treacherous Labyrinth With Ten Thousand Graves Where the Bottom Has Not Been Reached.

The Labyrinth, an abyss so deep not even the eye of god can pierce through to its very bottom. Hundreds and thousands of adventurers brave its tunnels, and are slain; people have yet to tread anywhere near its end, great unknown that it is. One girl, Chino, must, with the aid of _Constructs_, treasures from the labyrinth housing something akin to life inside their forms, challenge and survive its depths in order to save her sister, who is being slowly eaten away by a curse. But is what awaits her at the bottom of the labyrinth hope? Or despair?
