[DeepL Translation - needs review] Volume 1 Introduction: A world with a labyrinth created by the gods. Shun, a young hunter boy, teams up with Yua and Yuna, twin girls summoned from modern Japan, to conquer the labyrinth. Shun's "hunting" begins in this RPG-like labyrinth, where he fights with guns, swords, and magic!　However, it was a super-abandoned play itself that even summoners from other worlds and even Gods were beyond astonished and laughed at...?
