Now I'm a Demon Lord! Happily Ever After with Monster Girls in My Dungeon: Volume 13

For the first time in a long time, Yuki is enjoying life at home in the dungeon with his family. Unfortunately for him, a request for aid suddenly arrives from the Reauxgard Empire, where a horde of monsters is surging forth from newly discovered remains. He rushes to the rescue, but as he plows a path of destruction through the swarm, for some strange reason, who should he find at the end but...the Spirit Emperor?!

To no one’s surprise, though, this antihero of a demon lord manages to stave off the tide of monsters so he can enjoy playing the tourist in the imperial capital with his family and the Spirit Emperor. After having a ball on their trip, they head home, but their peace is short-lived, as another emergency message comes in from the empire—the Demon King is under attack. Time for Supreme Ruler Yuki to spring into action!
