Jigokuraku - Episode 7, 10 - Sagiri and Yuzuriha in Bath

Sagiri and Yuzuriha found a village with two sentient occupants. Even better, the place had a working hot bath.

The island's rulers had yin and yang forms (male and female). Ju Fa showed extreme possessiveness, no matter his body type. Tao Fa appears to get around because we've seen her with the jealous Ju Fa and, recently, Mu Dan.
