"Well, as a Ryu, it is my duty (mostly) to bring rain to settlements so that they can grow their crops and have their harvests. In these parts, Ryus are revered as gods and the humans will often offer up a male for one.  Mamonos obtain spirit energy through sex, and with that energy I can use my power to make it rain.
