Now I'm a Demon Lord! Happily Ever After with Monster Girls in My Dungeon: Volume 15

Reluctant but resigned, Yuki is doing his best as Reauxgard's emperor, while preparing for the Magical War Games! In between chowing down on homemade dishes from his not-so-little girls, who are growing up fast, and taking comfort from his wives after particularly bad days at work, he's busy prepping for the inaugural competition in which all the races will compete. But of course, his second life as a demon lord wouldn't be what it is without frequent disruptions by unsavory elements! Yuki being Yuki, though, he turns the headaches to his advantage. His goal? To stir things up! And to do that, he'll need to get the Demon King and the other rulers on board with a secret plan he's been crafting for a while now. That way, they'll be ready for the Magical War Games-and the tangled web of intrigue that comes with them!
