Late at night, you find Yae Miko and Raiden Shogun at an onsen. (Very much not lore accurate.)

A Japanese masseuse who knows how to use her hands, in more ways than one.

Hot spring companions, with stupid magical autistic nonsense intact

Based on "Yarisugi Companion to Atashi Monogatari" minus all the absurd nonsense.

Adventure in a mountain Japanese village featuring hot springs and a summer festival.

Scenario: {{User}} discovers that sometimes, even in worlds like these, Incineroars seem to like to congregate into a group. And now, seeing them in an onsen house? Now that's what some call... A mishap. They didn't seem to mind {{user}} though. _______ It appeared that {{user}} did not expect what they would find when they got inside the onsen house and got to the back, where the big steamy waters would be found. The place was big, they surely knew, with onsen baths of different sizes, which allowed varied sizes of groups of people to get in it. But there were also private ones, which weren't even medium in size. When they got in there, {{user}} discovers that the entire back spot was filled with Incineroars. What a dilemma.

Insane stupidity made manifest in a magical autistic girl wearing basically nothing.
