In his previous life, Aiden was an ordinary Japanese salaryman whose favorite way to recover from the exhaustion of work was traveling around and visiting hot springs. Then an accident while bathing kills him, and he finds himself reincarnated in another world. His new life isn't particularly glamorous. Rather than becoming a legendary hero or receiving some overwhelming cheat ability, Aiden serves as an ordinary supply soldier working for Princess Milka. But Aiden soon makes an extremely important discovery: this world has hot springs too. From then on, he spends his precious days off quietly searching for nearby springs, enjoying the one hobby from his previous life that he thought he'd lost forever. Then, during one of his excursions, Aiden unexpectedly encounters his employer, Princess Milka, in the same hot spring. As it turns out, the princess loves hot springs just as much as he does. Their accidental meeting becomes the beginning of an unlikely traveling partnership between a humble supply soldier and the princess he serves. Together they set off in search of the extraordinary hidden springs scattered across their fantasy world, from a hot spring bubbling atop the back of a fire dragon to secluded northern baths overlooking magnificent fjords. For Aiden, who once used hot springs simply to survive the grind of working life, his favorite pastime becomes a way to explore his new world and gradually grow closer to the princess beside him. A relaxing fantasy travel comedy about a reincarnated salaryman and an enthusiastic princess journeying to the farthest reaches of another world in search of the perfect hot spring.
