Xania repairs the castle, purifying the air and teleporting away before Anise can find her and start her scolding.

“I guess the event is going to start soon, but I think I remembered the triplets at the kitchen needing help with cooking but I don't really want to… oh, I've got an idea.”

Xania teleports towards a remote village where she detects a faint amount of dark mana belonging to her.

She looks around, finding the source of it easily and teleports to the ex-bandit.

“Hey.”

The bandit slowly turns around, originally busy with counting money.

“Huh? Whose…”

“Why are you here, demon?”

“You said you're a merchant.”

“Yes?”

“Good, I need food, send over a good amount to the edge of the cursed swamp around the latest… 3 days later.”

“That's too short, I would have to rush back now and prepare everything.”

“Then you better get to it.”

Xania teleports away, leaving the guy there, processing what Xania just ordered of him before rushing to his horse to quickly go back, mentally cussing at Xania.

“Ok, the food problem is solved, what else did I need?”

“Oh ya, the participants, Anise didn't look too happy when I told her to deal with it… luckily…”

Xania uses mana on herself, concentrating for a moment before making a clone of herself.

“Ah ha! A clone, this'll be convenient.”

Xania teleports the clone to Anise, controlling with and handing Anise a note with the clone. Anise reads the note, looking back at the emotionless clone of Xania's, teleporting away to do her other task without asking anymore.

“I think Anise is sick of me, I ought to reward her with something since I'm confident she does more work than I do.”

“I wonder if there's anyone I know who's participating.”

Xania teleports the participation scrolls to herself, finding familiar names almost instantly due to her multitask magic.

“Hmm, Dragrove, Sliver, Graunter, Davien, the weird paladin girl or whatever her name was. Alright, that's about it, though it's a shame Anise isn't joining, she could probably win… right! Actually, between Anise and Davien, who is stronger? Because those two are definitely the strongest of the 4.”

“I guess I'll never know.”

Suddenly Anise teleports to Xania, stopping Xania as she tries to teleport away by pulling her by her tail.

“My lord, you're not going anywhere.”

“.... My freedom is gone.”

“Who are you to say that?! You gave me so much work!”

Unauthorized duplication: this narrative has been taken without consent. Report sightings.

“Ha ha ha?” Xania smiles sheepishly, making Anise sigh and letting go of her tail.

“My lord, why didn't you make any toilets for all the homes?”

“What's that?”

“What's what?”

“Toilets.”

“Huh? You don't know what a toilet is?”

“Yea.”

“Have you never used one? Wait… yea, I've actually never seen you go away to use the toilet, you only enter the bathroom to shower every once in a while.”

“What? What do you mean ‘watch me’.”

“As I was saying, you haven't made any toilets.”

“Hey… don't change the topic.”

Anise places her right arm on Xania's shoulders in a comforting manner.

“My lord, you should use detection magic and check for any surveillance or scouting magic periodically.”

“...”

“Anyways, I guess demon lords don't need to use the toilet so it makes sense that you don't know since only some knowledge and talents was transferred from past demon lords.”

“So what's a toilet?”

Anise teleports them both to the bathroom and points to the toilet.

“That.”

“That?”

“Yes.”

“How to use?”

“Sit on it since you're a woman.”

“If I was a guy?”

“Then you would have both choices.”

“So I should sit on it?”

“And people usually strip, but how about I teach you in the next lesson in my free time?”

“sure?”

“So, look at it, remember it.”

“Ok, I remember the shape and the teleportation magic circle and the cleaning magic circle.”

“You're confident?”

“Yea, why?”

“Go make one in each bathroom.”

“Each? For the whole castle?”

“I already made the toilets for each bathroom in the castle, you on the other hand are going to make one for each bathroom in every house.”

“Every house? There are thousands!”

“Better get started in that case.”

Xania reluctantly teleports out, using her detection magic in every house to scan the environment, looking for a suitable place in the bathroom to fit a toilet, along with making sure the person inside can use the toilet no matter their body size or shape.

After a couple hours later along with some clones, she manages to complete it, intending to go back and rest as Anise appears in front of her again.

“My lord, I see you're done.”

“Yea, I'm going to rest now.”

Anise grabs Xania's tail again, not letting her just walk by.

“What now?”

“You need a place to store all the excrement from the toilet, better get to it.”

“Fine, though I have no clue what excrements you mean.”

“And make it so it'll burn properly and be properly closed up.”

“Fine.”

Xania digs a small hole under the castle using magic, making a box of steel with fire magic burning everything inside every 5 minutes.

“Done.”

“And make it so the ashes go somewhere else, somewhere far away or kept safely so nobody will touch it by accident.”

“...”

Xania adds a teleportation circle to send it to the crater left behind from the abyss incident.

“Nobody will find it there, happy?”

“yup.”

Xania starts walking by Anise, watching her closely, making sure she doesn't try grabbing her tail again.

As Xania keeps watching, Anise moves her hand out towards Xania's tail, causing Xania to immediately move her tail away.

“Not happening.”

Anise's hands move to Xania's horn suddenly, surprising her and not giving her time to move.

“...”

“Go make us a stadium with seats for different types of demons and toilets.”

“…”

Xania uses magic, using spatial magic to make the inside of the castle much bigger and creating a stadium inside with her requirements.

“Now, are you satisfied?”

“Well, there's still the need for barracks in the training grounds, proper roads, hygiene, weapons, defences, manga circles made for defending and a couple more.

Xania uses her magic conjuring up everything Anise said at once.

“See my lord, you can save me so much time if you'd just contribute properly.”

“Anything else?”

“Yea actually, and you're not gonna go anywhere till I'm done.”

For the next 3 days straight, Xania was forced to follow Anise around, doing everything she said, such as purifying the poisonous air slowly getting in, adding mana to the mana stone sustaining the barrier around the castle, providing materials for the blacksmiths, purifying the whole of the cursed swamp, causing people to call it a divine miracle with some people coming to investigate but all getting killed by Xania. Some more include using her scythe to send a wave of mana, flattening out a piece of land for Anise to create some buildings on, including a farm which the elves asked for.

Afterwards, Xania ran away from the castle, returning a day before the festival started, avoiding Anise as much as possible.

“I now see why humans pray to a god for help…”

Xania takes the participant list, finding a grand total of 5000 participants, making her sigh.

“3000 participants would take 2 whole days to go through, but 5000 would be around 4…”

“Indeed my lord.” Anise suddenly appears behind Xania, grabbing and pulling her tail as the she's tries to protest, to absolutely no effect.

Anise continues dragging Xania as she just sits on the floor, letting herself get dragged along.

Xania just sighs, not doing anything more as Anise drags her to the bedroom to brief her on what to say tomorrow.
