After an untimely death, a rather average Romanian is reincarnated in a new body in a new world filled with Magic and Adventure! The only problem is that he isn't exactly humanoid or has any hands for that matter. As the Dungeon Core installed in a Magic Academy, his role in this world has already been set by his creator, a bearded old wizard, that of a janitor and a repairman. Still, will he obediently stick to his 'job' when he holds the memory of his past life, has access to incredible magic, and most importantly, feels the need to build himself a good ol' labyrinth?
