Black Tokyo Unlimited: The Races of Black Japan (2013)

From publisher blurb:

The delightful monsters described in Black Tokyo Legends: Races of the Tatakama aren’t the only character options for the players in the setting. The Tatakama is an endlessly changing, ever-new realm of wonders, and in the Black Else, the only way to survive is to mutate and evolve. And in the Earth realm, greed and lust have combined to breed entirely new species of submissive sex-pets that blend human, animal and robotic traits into a seductive whole.

New species emerge with alarming regularity; some temple maidens claim that there is an oni for every lustful thought ever shared by a human. If that’s true, the Black Else is home to an endless array of monsters. And some of these monsters venture into the Earth Realm, to protect or plague humanity….

These new races spend the majority of their existences in the Earth Realm, and even though they are creatures of magic themselves, are strangely uncomfortable in the Tatakama, for one reason or another.
