   Summary

   A lowly demon gifts high celestial witch and master artificer Seonghwa with a strange cube he found in the infinite library of Hell. The witch usually works for a hefty price, but his boundless curiosity leads him on a journey below fiery depths, and into the jaws of a rabid, vengeful monster.

   Is seeking Truth worth making a deal with the Devil?
