Urban Dungeon

"There will always be someone who has to do the job. That someone might as well be me." A middle-aged man living by that simple belief suddenly finds himself caught up in events that will change his life forever. Dungeons have appeared. The world is changing. And for reasons he would very much like explained, he ends up becoming a beautiful young girl. A modern fantasy featuring dungeons, monsters, guilds, and a protagonist who is far more concerned with getting things done than worrying about his new body. After all, he's an old man. The usual gender-swap panic isn't really his style. Author's Note: This is an original work by a Japanese author, translated from the Japanese web novel originally published on Shousetsuka ni Narou.
