There's a lovely teahouse in the town of Mostropia but, since the small city is a safe haven for monsters, it shouldn't be surprising that the owner of such sweet establishment is an oni, and yet... His figure is very contrasting with the place.

The guy is huge and often towers over his costumers, not to mention his tusks and horns are pretty scary.

Still, from what you've been told, despite his constant scowling the oni is a very good host and his tea is excellent so... You decided to give the teahouse a try.
