Survival in Another World with My Mistress! (Light Novel) Vol. 10

After long months of building settlements around the kingdom and rescuing captured beastmen, Kousuke is looking forward to some R&R. With new allies in tow, he and his friends return to the capital city...and his growing family! Between welcoming his and Elen's new child into the world and spending time with his harpy partners, Kousuke's daily life and heart is full. But when an invitation to the Dragonis Mountain Nation's memorial service arrives, it puts everyone on edge. Just what is this service truly for, and why do they want Kousuke there? And while his friends puzzle over these questions, Kousuke busies himself with something else entirely: crafting a giant airship!
