Dungeon Tou de Yadoya wo Yarou! Souzou Mahou wo Moratta Ore no Hosoude Hanjouki

One day, Sanada Shirou, who worked for an exploitative company, was transported to another world. He gained the power of "creation magic" during the transmigration, and he planned to lead a slow life by opening an inn, but this other world turned out to be a little different?! It is a world where women are overwhelmingly dominant, where the women fought and did the dangerous work, while the men are powerless and meek! Every day he'll be treated (in many ways) to the hospitality of the women of this strange world—!
