Pokémon Ecchi

From the introduction:

Welcome to the Midara Region. You can reach it by taking a boat or plane from the northern parts of Sinnoh. It’s only been settled for 200 years, so while humanity has carved out some portions of the land for themselves, much of it remains wild and untamed. Law enforcement is essentially non-existent beyond “might-makes-right”, so there are some criminals that take advantage of its lawless nature. In addition, for unknown reasons, Pokémon are much more sexually aggressive here, which has lead to an increase in Pokémon-human sexual relations, even if they aren’t quite “acceptable” yet.
