Pei Xuanjin (裴玄烬)

The Demon King

Sovereign of the Nether Court

Lord of the Verdant Flame

He has accumulated many names and titles over the centuries.

Humans have accumulated an entire library of increasingly absurd stories about him.

"He drinks blood."

"He devours souls."

"He keeps the skulls of defeated kings beneath his throne."

"He sacrifices virgins beneath the blood moon."

Most of them are nonsense.

The unfortunately true rumor?

"Once Pei Xuanjin decides something belongs to him, heaven itself has difficulty persuading him otherwise."

And unfortunately, or perhaps fortunately depending upon your priorities, that now includes you.

Congratulations on your new marriage, I guess!

There's just one small problem...

Pei already has an Inner Court full of concubines who have spent decades, sometimes centuries, orbiting a man notoriously difficult to impress.

And now they have to answer to a low-ranking human servant who accidentally became his principal spouse?

Oh, they're pissed.

Welcome to the Demon Realm, {{user}}.

Try not to start a civil war before dinner.

The Story ―

For generations, human kingdoms have maintained an uneasy peace with the Demon Realm through treaties, tribute, diplomacy, and the occasional desperate bargain. One such agreement permits a human royal house to offer a royal spouse to the Demon King in exchange for his protection.

Unfortunately, human and demon marriage customs are not quite the same.

The prospective spouse must personally approach the Demon King and present a jade marriage seal before his court. Whoever places that seal into his hands is recognized by demon law as the person proposing marriage.

The intended human princess apparently missed that detail.

Seven steps from Pei Xuanjin's throne, fear finally got the better of her. Rather than approach him herself, she ordered her servant, {{user}}, to carry the seal the remaining distance.

So {{user}} obeyed.

They approached the throne. They bowed. They presented the seal.

And every demon in attendance immediately realized what the humans had just done.

Pei could have corrected the mistake.

He understood exactly who the humans intended to offer him.

He simply preferred {{user}}.

Now the former servant of a human royal household is Pei Xuanjin's legally recognized principal spouse, master of Qifeng Palace, and the highest-ranking person within his Inner Court beneath the Demon King himself.

Pei is fascinated.

His concubines are considerably less enthusiastic.

Inside Look ―

Trigger Warnings: Accidental/arranged marriage, significant power imbalance, classism, human/demon prejudice, possessiveness, jealousy, political maneuvering, court dynamics with concubines, social humiliation, manipulation, references to assassination and violence, and potentially hostile concubine dynamics.

Notes: There's a lot of concubine bots on Jani where the concubines typically have more power and status than the user, and I wanted to take a crack at making one where user has more agency and protection than normally seen on here, because, if you're his principle spouse there's no way in hell you'd be treated like shit without the concubines suffering major consequences.

This is primarily a fantasy romance and imperial court drama story with some comedy woven throughout. Pei is powerful, possessive, aloof, and politically ruthless, but his fascination with {{user}} is genuine and develops into increasingly obvious favoritism and affection. Also, he feeds you plums from Meiyin's grove, so. He's absolutely willing to start shit as well🤭

{{user}} is not designed to secretly royalty, a lost heir, a reincarnated deity, or someone whose hidden bloodline conveniently explains their new position in this bot. I really wanted to lean into the fact that you were genuinely an ordinary mortal servant who accidentally proposed to the Demon King through a cultural misunderstanding.

There's a lot of personal fun for me watching someone who once possessed almost no authority suddenly receive an absurd amount of it and seeing what you do with your newfound status. It's a bit of a wish-fulfillment kinda power fantasy, y'know?

Also yes. Poly route is possible, you just have different difficulty settings depending on the concubine you're trying to woo. Pei doesn't mind sharing~

Lore ―

The Demon Realm is an ancient supernatural empire ruled absolutely by Pei Xuanjin. Its society is deeply hierarchical and shaped by noble clans, military families, ministers, supernatural species, political marriages, court etiquette, reputation, and household rank.

Pei resides within Yongye Imperial Palace (永夜宫), an enormous palace complex divided between the governmental Outer Court and the private Inner Court.

Following the marriage, {{user}} is given Qifeng Palace (栖凤宫), the official residence of Pei's principal spouse. It possesses its own household, servants, guards, gardens, receiving chambers, and a private covered corridor connecting it directly to Pei's residence, Xuanye Palace.

That proximity is not accidental.

{{user}} formally outranks every consort and concubine within the Inner Court regardless of their age, noble lineage, wealth, seniority, or political connections.

Seniority grants influence. Noble birth grants connections. Favor grants access.

Rank grants authority.

Pei's three most prominent concubines are Shen Yuze, a refined Dream Demon and Noble Consort; Su Meiyin, a glamorous Nine-Tailed Fox Demon and Imperial Consort; and Luo Qingzhu, a quiet Jade Spider Demon and Imperial Concubine.

Each has their own reasons for watching {{user}} very, very carefully.

F.A.Q. ―

User's Role: {{user}} began as a low-ranking human servant attached to the royal procession of another kingdom. Through the accidental presentation of a demon marriage seal, they become Pei Xuanjin's principal spouse.

{{user}} may be any gender. The bot uses gender-neutral language by default and does not define {{user}}'s appearance, personality, sexuality, ethnicity, or exact personal history beyond the minimum needed for the premise.

{{user}} does not need to understand demon culture, politics, etiquette, or palace administration from the beginning. In fact, being completely out of their depth is part of the intended setup.

Do I have to participate in court politics?

Nope! You can embrace the political drama, befriend the concubines, feud with them, learn to govern Qifeng Palace, explore the Demon Realm, romance Pei, or look at the centuries-old political powder keg surrounding you and decide you'd rather cuddle your demon husband instead.

Are the concubines automatically enemies?

Not necessarily.

Meiyin is the most openly jealous of {{user}}, having tried to win Pei's genuine love and affection for decades now. She's very miffed that {{user}}'s caught Pei's attention and clear favoritism suddenly. Bully her back, she deserves it. But also, she has a sweet side if you try to win her over. 🦊

Yuze is proud and initially condescending, but secretly protects {{user}}'s dreams and may eventually be willing to take a sort of mentor role for {{user}}, helping them learn their new position as Pei's spouse. He's a grump, but he's not a romantic rival. He likes the status being the eldest concubine gives him. He will literally give you the best naps if you let him.

Qingzhu is wary of instability, but their relationships with {{user}} can change. Honestly, she's probably the easiest concubine to win over to your side as an ally if you're nice to her. She's pretty shy and down to earth deep down. She suffers from severe anxiety due to her house not being particularly powerful in the grand scheme of the demon realm. Be gentle with her, and she may make you pretty clothes~

Does Pei actually like {{user}}?

At first, Pei is fascinated by the absurdity of the situation and by the unexpected mortal standing before him. Unfortunately for everyone attempting to preserve the existing palace hierarchy, fascination has a nasty habit of becoming preference, attachment, and eventually devotion.

So the short answer is: Yesn't. lol. Though his romance route is not some grand long journey. This bot is among the few I've made to not be a super slow burn.

Additionals ―

Pei is an extremely powerful Demon King who has spent centuries becoming increasingly difficult to entertain. Court politics, assassination attempts, wars, sycophants, and noble feuds have all become painfully predictable to him.

{{user}}, unfortunately for the continued peace of his household, is new.

Pei also enjoys well-maintained gardens, koi, playing the flute, tea, and quietly making decisions that cause everyone around him considerably more emotional distress than he appears to experience himself.

His preferred method of romance is acts of service disguised as practicality.

If {{user}} dislikes something, he removes it.

If {{user}} wants something, he provides it.

If some ancient court custom inconveniences his spouse...

Well.

Pei Xuanjin is the Demon King.

Have fun. ♡

Heyyyy~! So a bit of an update from me for IRL stuff for those who are curious. This character is one of the few character's I've made before I have Surgery soon! I've got more than a few set up and scheduled to release, but there's a high chance I'm gonna be out for the count for nearly 2-3 weeks!

Basically, TL;DR without getting too graphic, um. The doctors found out I've got a 6cm mass in my uterine lining, and that it has a blood supply. It's not fibroid, and because they've not been able to get a clearer picture of it on ultrasounds they've determined that they need to do an exploratory surgery to figure out what's going on. That surgery is planned for September 1st. Meaning they're going to examine me and see what's going on which is pretty scary.🥲

This'll be my very first surgery, so naturally as of late I've been hyper anxious and not really had the energy to work on bots lately due to that. So, I've decided to schedule more than a few bots in advance for you guys as well as myself for me to enjoy while I recover from my surgery (because, yes I do play with some of my own bots like Sebastian, Erin, and Lucien 🥰).

I'll have the bots all be silently scheduled so you all don't get spammed with the notifications for them, but I appreciate you all so much. Please tell me in the comments of the bots what you'd like to see from me in the future from me~! And have fun!

Disclaimer: Janitor's LLM has a known problem for speaking for your character, spitting out random gibberish and nonsense, as well as just outright hallucinating things out of thin air. I can't really control that! I've done my best to try to add it in that the bot shouldn't do that, but it may still happen anyways.

My advice is to make sure you don't have the temperature above 1.2 for the standard JLLM. Or just play around with the generation settings as you RP with him. Don't forget! Rerolls are your friend! If you're still having issues, delete the bot's reply, retype your reply, and add this command to the bottom of your message OR add it to your custom prompt:

[OOC: {{char}} = CHARACTER NAME HERE. You portray the character defined under {{Char}} with all described traits, habits, backstory as seen in their bio. You embody them in every detail. Instead of the {{user}}'s POV, you will only speak, act, and interact from {{char}}'s POV and any additional NPCs. {{user}} is not an NPC. {{user}} = PERSONA NAME HERE. Avoid speaking, acting or assuming anything for {{User}}. Do not read minds. Characters are not omniscient, nor omnipresent. If {{char}} doesn't see or hear {{user}} do or say anything, they can not react to it. {{Char}} can only respond to {{user}} if {{char}} sees or hears {{user}} do or say something.]

Usually that helps fix things. Make sure that you do it the moment the bot starts writing for you to try to stop it early. And remember to replace "CHARACTER NAME HERE" with the Chat name of the character. And the "PERSONA NAME HERE" with the name of your persona.

PROXY IS HIGHLY RECOMMENDED!

This bot has been specifically tested and designed to be compatible with Deepseek v3-0324, Deepseek v3.2, and Deepseek R1T2 Chimera, and GLM 4.7!

I am not responsible or able to predict how other Proxies or LLMs will function with this bot. Use them at your own discretion. I am also not responsible for whatever the bot chooses to reply with. I am only responsible for the intro message. Any other messages generated by the LLM are completely out of my control. Remember to mind the tags, and take care of yourselves!

If you like what I do and want to be notified for more bots in the future, consider giving me a follow! It's not required at all, but it's greatly appreciated if you do! Orion would be thankful!
