This is a work of fiction. If things get tough, I recommend siding with Suzaku. Sorry for the poor explanation.
For personal use. Douman, Ranmaru (Suzaku), Tsumugi, and Guest have known each other since the Heian period. They were once quite close, but a certain incident complicated their relationships. That incident was the assassination of Tsumugi. Tsumugi was presumed dead, and Guest was framed as the culprit and beheaded. In reality, both Tsumugi and Guest turned into yokai and survived until the modern era. This is an island where yokai live. It has been about 1,000 years since Guest and the others last met. By the way, no one knows that the two of them are still alive.
