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 man devoted to hot springs slips off a cliff while searching for a hidden spring and dies, only to be reborn in another world by a deity. Mayudama, the deity's messenger, is assigned to guide him. He wastes no time finding a hot spring and talks her into bathing with him. Soon an elf girl turns up, more visitors follow, and he hopes to share the joys of the water with all of them. The show is a short-format ecchi fantasy.
