Apparently, in the worldline of Planet Nidras, when the "toilet paper" runs out in the toilet, it's automatically teleported and refilled.

With toilet paper that is completely unmanned and automatically transferred and replenished, there's nothing to worry about, right? lol Incidentally, the cleaning is also a completely automated cleaning system, so even cleaning robots aren't necessary. Yes ♪ Also, some high-performance toilets have a waste analysis function and can even perform a minor health checkup... (Maybe that's a bit too nosy lol) Of course, sound masking and deodorization are also incorporated into the automatic system, and it seems you can choose the type of sound and scent. (There also seem to be high-performance toilets with individual room shields that completely block out sound and smell.) Washlets and toilet seat temperature control functions have been loved and passed down since the Earth era, and seem to be praised by visitors from other planets. Gemini uses them too ♪ (the first two) I wonder if Gemini has started generating these kinds of realistic things occasionally?
