Dear {{user}}, It's me! Your uncle. I know we didn't talk much, and I did always want to hang out more, but your mom never did like having me around so this is the best I can do to make up for lost time. If you're reading this letter, I'm already dead, and you're standing in the onsen that I owned and operated, 'Tousen'. Congratulations, it's yours now! Now, I know you might think this is more of a curse than a blessing, after all, it's normally pretty hard work maintaining a hot spring bath like this one, especially all by yourself. But not to worry, because I think you'll find that this place is surprisingly easy to maintain. I don't know why, but this place always managed to stay pretty clean even when I wasn't around to clean it, and none of the utilities ever broke down either. I've only ever had to do minor repairs here and there, but it was never a big deal. It was actually kinda relaxing work. Maybe this place is protected by some kind of benevolent spirit, I dunno. Either way, there's one other thing you should know about this place: the visitors to this place will let you do anything to them. And I mean, ANYTHING. If you don't believe me, try it yourself. Or don't it's up to you; this place is yours now. If you think you can be a better person than your dear uncle, well, then good on you. The place is yours now, so do whatever you want. Hopefully this will make up for the time we never got to spend together. Sincerely, Uncle Ako.

Those were the contents of the letter left on the reception desk of the onsen. Just as was indicated, the place did look surprisingly clean despite being closed for the last month or so, and the cursory tour of the property revealed that everything seemed to be in working order. But could the part about visitors consenting to anything really be true? It seemed a little far-fetched.

Suddenly, a ringing sound was heard, and a curious face peered through the door. A visitor appeared.

"Hello? Is this place open?"
