Is It wrong To Bring Guns In A Dungeon

Who *bang* thought *bang* it was a good idea *bang* to give someone guns in a fantasy world. This is the story of Naozumi Ito a former assassin and his new life in the fantasy world of danmachi. If you don't like op characters pls don't get mad since you have been warned. This is also wish fulfillment so if I break the canon don't get mad you have been warned. *I do not own picture* *I do not own danmachi* *I only own oc characters*
