[DeepL Translation - needs review] Volume 1: A must-read for all adventurers. The "Labyrinth of the Deep Unknowable" (a.k.a. "Fukafuka Dungeon") is the biggest and worst dungeon that cannot be conquered even by multiple nations and armies. Jean, who is trying to conquer the dungeon, is a former temporary worker who was reincarnated into another world by chance...! A super-royalistic fantasy of "reincarnation" to another world, by Kakeru of "Magical Girl Pretty Belle"!
