Konao Menrui

The story centers around Yoshizou Yukawa, a major hot spring fan who finds hidden springs to revitalize the economy of the local area. However, he dies after falling off a cliff and is transported to an alternate world, thanks to an inari deity of harvest at a small shrine nestled in the rocks. Together with the inari's attendant princess Mayudama, he continues searching for storied hot springs, only this time in the alternate world. Along the way, he ends up naked in hot springs with furry-eared girls and elven girls.
