I like these two! What's their story?

They each belong to a separate clan who worship opposing deities in the forms of a Sun and Moon god. Kurenai, the female, can channel the power of the Sun god and Kuronosuke, the male, channels the Moon god. The two clans share a border and a truce which forbids certain acts against each other, but is often still contested and conflicts happen between opposing sides.

Because of their being aspects of each clan's god, these two hold the high ranks of future heads of the main families and were raised together for a time with the intent that they might one day marry and unite both clans.

Honestly intriguing, and can be ripe with all sorts of plot and drama details (and not just the obvious incoming porn, lol!).
