【Manga adaptation begins April 2nd on "Manga UP!"! The book version is available up to volume 3.】

Our protagonist is reincarnated into another world as the max-level wizard they used in the classic TRPG "Dungeons & Braves." However, this other world was threatened by its natural enemy, the "Dark Oni." A plucky merchant's daughter, an arrogant beautiful sorceress, an intelligent adventurer, and a female dark elf. Having gained many companions, the protagonist decides to protect this other world from the Dark Oni. This is a nation-building adventure fantasy about an old man protagonist who, despite possessing cheat-like abilities, is riddled with weaknesses, can't make a move on the beautiful women and girls surrounding him, and daily grapples with the vast differences in common sense in this new world—yet somehow still manages to become unrivaled.
