To Another World... with Land Mines! Volume 11

Nao and his friends escort Illias back to Pining, but they hardly get a chance to rest and recover before they’re swept up into the investigation of a series of kidnappings. With hard work and a little luck, they quickly crack the case and apprehend an unexpected culprit. As a reward, they’re granted the rights to the land around the dungeon they discovered, and they pass their time comfortably: exploring the dungeon, rock climbing, mushroom foraging, and throwing a flower-viewing party. But nothing can remain the same forever, and soon, under the enchanting moonlight, Nao finally musters the courage to confess his true feelings to Haruka.
