Milk-shibori Hunter no Isekai Sakunyuuki ~Nouka no Saenai Otoko ga Arayuru Shuzoku no Chiku-B wo Moteasobi-toriko ni Suru~

Kakeru Endo leads an unremarkable life as a dairy farmer in rural Hokkaido, his days defined by the steady rhythm of tending cattle and the quiet solitude of the countryside. That mundane existence comes to an abrupt and bewildering end when a simple bath somehow becomes the gateway to a fantastical realm. In this new world, however, magic is not woven from arcane chants or ancient relics—it is drawn from a far more primal potent breast milk of magical beasts. This miraculous liquid serves as the foundation of civilization, powering everything from humble household tools to fearsome weapons of war, and it is the lifeblood that keeps the common people alive. Those brave or desperate enough to harvest this vital resource are known as Milk Hunters, yet their numbers have dwindled to a critical few. Across every kingdom, the supply of milk is drying up, plunging the land into a crisis that threatens to collapse society itself. Summoned across dimensions to fill this desperate void, Kakeru finds himself thrust into the unlikely role of a savior. He quickly realizes that his years of patient work on the farm have given him a singularly useful skill set: a deep, instinctive understanding of how to handle and milk large, skittish animals. Now, he must adapt those humble techniques to an array of exotic, often dangerous, magical creatures. To collect the fresh, high-quality milk needed to stave off disaster, Kakeru must learn to properly arouse and soothe these beasts, navigating a perilous new profession where his success is the only thing standing between the world and total ruin.
