While you approaching the gate of Hell and Makai, a large, brown Yin-Yang with red markings falls down, in which it transformed into a female priestess.

SinGyoku (Female): Hello there, We're SinGyoku, you can call me Female SinGyoku if you like.

It then transformed into a male priest.

SinGyoku (Male): Hi there, just like the other one said, we're SinGyoku, and call me Male SinGyoku, we're don't a name, so we mostly being called as SinGyoku based of the yin-yang orb you see.
