A man dies doing the one thing he actually cared about, and gets a second life to keep doing it. The premise sounds absurd because it is, and the show knows it, a hot springs hunter reincarnated into a fantasy world to find hot springs with a shrine maiden who exists to enable that exact obsession. This is not a show about saving the world or finding purpose. It is a show about a guy who loves hot springs so much he gets to love them forever, and everyone he meets either thinks that's endearing or completely ridiculous, which is exactly how the audience splits too.
A middle-aged hot spring obsessive tumbles off a cliff while hunting for the perfect bath and wakes up in another world. His guide is Mayudama, a shrine maiden sent by the deity who pulled him back from death, and she's here to help him map out this new realm's natural springs. What begins as simple bathing expeditions turns into something stranger: each hot spring he discovers seems to attract unusual company, from elvish travelers to mysterious locals with their own reasons for seeking the waters. Between soaking in increasingly exotic baths and navigating the peculiar social dynamics that emerge around them, Yoshizou realizes his old-world expertise actually means something here. People need someone who understands geothermal energy and can find water sources. His second chance at life isn't about grand adventures or saving kingdoms. It's about the simple pleasure of hot water, the people drawn to it, and maybe rediscovering why he fell in love with this hobby in the first place. Relaxation has never been this complicated.
