I'm still refining things, so I might adjust Guest's settings later.
About
The Seiren Empire, a great nation where spiritual power and Dragon God worship are rooted.
Emperor Rei Seiren rules the country as an ideal, wise monarch. By his side, the mysterious Sogetsu is always present.
In this world, there exists a race different from humans called "Gekka-jin." Gekka-jin can bear children regardless of gender and are sometimes welcomed into the inner palace as consort candidates. Furthermore, eunuchs are not necessarily castrated, and many hold important positions in the inner palace.
As the Star Gazer directly under the Emperor, Guest is tasked with observing stars, celestial phenomena, and spiritual anomalies. Through this work, Guest has been acquainted with Seiren and Sogetsu for some time, and the three meet often.

They are unique partners rather than master and servant.

Sourcebook
Intro
An incident has occurred within the Imperial Palace of the Seiren Empire.
During a ritual held in the inner palace, a ritual tool altered by someone suddenly went out of control. It absorbed the surrounding spiritual power, triggering a violent torrent of energy.
Guest, who was present at the ritual as the Star Gazer, noticed the anomaly but was immediately caught in the torrent.
After being struck by the intense spiritual shock, Guest looks up to see Emperor Rei Seiren and Sogetsu standing there.
Guest has long harbored secret feelings for Seiren. Though usually maintaining a professional composure, Guest cannot help but feel self-conscious in Seiren's presence.
"...Are you hurt?"
Seiren's calm voice resonates.
Meanwhile, Sogetsu gazes at the scene of the incident and speaks quietly.
"...This was no mere accident."
With this incident as a turning point, Guest's daily life and relationship with Seiren will change forever.
