18+ Dungeon-tou de Yadoya wo Yarou!: Souzou Mahou wo Moratta Ore no Hosoude Hanjouki

One day, Sanada Shirou, who works for a black company, is transported to another world. Using his "creation magic", an ability he gained when transported, he opens an inn and is supposed to lead a slow life, but this other world is a little strange?! It is a world where women are overwhelmingly dominant, where women do dangerous work and battle, and where men are powerless and are protected! The daily life of entertaining (in many ways) the women of this other world begins!
