Eisei

* Novel
* Anime

**Eisei** (衛青, *****Eisei*****?) is a eunuch who serves as an attendant to the Emperor, Ka Koushun.

## Appearance

Eisei is a young man with dark hair. Because he is a eunuch, he has a high voice and a beauty that matches it.

## Personality

Eisei is deeply loyal to Koushun and despite questioning his decisions sometimes, he generally follows wherever he goes. He does not tolerate disrespect to Koushun. He seems to be prone to believing the rumors about the Raven Consort.

## History

Eisei met Koushun when the latter was ten and was immediately made his attendant. When Koushun was deposed as the crown prince, Eisei remained a hidden ally to him during that time.

## Plot

Eisei accompanies Koushun to visit the palace of the Raven Consort, despite his unease over the rumors and the creepy atmosphere around the building. When they get there, a golden bird named Xingxing comes out of the doors and is caught by Eisei before it could attack Koushun. Eisei is about to strangle it, but he is stopped by Ryuu Jusetsu. He, like Koushun, is surprised at her youth and appearance. He gets kicked out along with Koushun after Jusetsu refuses to listen to Koushun's request to find the owner of a jade earring he found. Eisei doesn't like the blunt and arrogant way Jusetsu talks to Koushun and questions why Koushun must ask her to fulfill his request.

The next day, Eisei accompanies Koushun to Yamei Palace again, carrying a basket full of baozi for Jusetsu. Jusetsu agrees to listen to Koushun's request, though she doesn't have the ability to find the owner. Koushun then asks her to find the identity of the ghost possessing the earring. Eisei is nauseous when he sees the grotesque appearance of the ghost possessing the earring after Jusetsu summoned it. Koushun asks Jusetsu to help the ghost move on, which she begrudgingly agrees to. She asks for the name register of all the concubines in the inner palace in the previous reign and the one before that, but Koushun refuses because if he directly asks for it, people will know that he is up to something. Koushun orders Eisei to pull some strings to get it, and Eisei says it will take some time. Koushun also secretly tasks Eisei with investigating the flower-shaped burn on Jusetsu's wrist.

After finishing work in the Outer Court at noon, Koushun and Eisei return to Gyoukou Palace. Eisei makes tea for Koushun. Koushun asks about the investigation and Eisei relays everything he learned about the You clan, the clan who bought Jusetsu to be a house slave when she was four years old and branded her with the osmanthus flower-shaped mark. Eisei is unable to find out who they bought Jusetsu from. He does not think it is a wise idea for Koushun to be involved with someone whose origins are unknown, but Koushun believes that this is necessary.

Eisei sneaks into Yamei Palace through the back door and catches Jusetsu in the middle of making a position. He glances at the contents of her mortar before looking away, recognizing what they are and guessing their purpose. He asks Jusetsu if the maid's uniform was useful and Jusetsu tells him about what she discovered, including about Lady Han. Eisei admits he doesn't know much about the inner palace during the previous rule since he had always been by Koushun's side. Jusetsu asks if he can find out if any of Lady Han's servants are still in the inner palace, but Eisei tells her that he can't read the court lady register unless he has a reason, which will reveal that Koushun is involved in this. Jusetsu comes up with the idea of using the pretext of finding a maid named Jiujiu (family name unknown) to work at Yamei Palace in order to gain access to the register. Eisei agrees to this idea. Before he leaves, he reveals to Jusetsu that he knows what she is making and asks who she is.

Eisei tells everything that happened to Koushun. At night, the two go to the pond near Yamei Palace and catch Jusetsu in the act of washing off the black dye from her silver hair, proof that she was a descendant of the previous imperial dynasty who were all executed by Koushun's grandfather. Jusetsu sees them and runs back to Yamei Palace. Eisei follows Koushun as he returns the bowl of dye at the door and tells Jusetsu that he saw nothing tonight, before leaving with him.

Later, Koushun and Eisei carry out Jusetsu's plan successfully and are able to find out about Lady Han's servants and their current fate. They go to Hien Palace and bring Jiujiu with them to Yamei Palace. Eisei carries Jiujiu's new uniform with him and shows it to Jiujiu upon Koushun's prompting when he sees her hesitating over being Jusetsu's handmaid. After Jusetsu and Jiujiu leaves for Sen'e House to speak with Lady Han's handmaid, Eisei orders one of his underlings, Onkei, to guard Jusetsu from the shadows and follow her.
