Maid dragon x reader x demon slayer

A spider on the wall

IMPORTANT! PLEASE READ
so um, if you have seen the anime 'the promised neverland' there's this character called Isabella. She's going to be your sister in replacement of your older brother. I rewritten the chapters so I hope it doesn't confuse any of you guys.

Also, I um, made a new book. It's a demonslayer x the promised neverland reader x hunter x hunter so if you want to see that you can.
Also, merry late Christmas!

"I see the guests have multiplied y/n... care to explain?" Isabella asked wearing an unreadable expression while looking out at the dragons arguing with the demonslayers.

"Uhh. Uhhhhhh. I-I don't know what you're talking about...?" Y/n stuttered while sweating nervously.

"Y/n, I just came back from grace field academy and I don't think I have the energy ever since I just had a twenty one exams." Isabella said while sighing.

"As long as your friends don't cause much trouble I am fine with it however, when they start to cause any sort of chaos, this needs to stop immediately." Isabella warned as she stood up from the sofa.

"Are you going out again?" Y/n asked, disappointment evident in her voice. Isabella only looked at her sister and sad smiled while nodding as she began wearing a coat.

"But you said you just came back from school! Not to mention grace field academy is a boarding school! Can we not spend time together?" Y/n asked while standing up from her chair making the black to h/c haired girl flinch a little.

"...I'm sorry y/n." Isabella said as she walked towards her room, presumably to get her bag. Y/n only looked down at the floor and clenched her fists, disappoint evident in her eyes.

"Y/n-Sama! The girl looking boy is telling us to fight him! Please tell him to stop!" Tohru shouted as she began pointing at Inosuke who was trying to headbutt Kanna only to be held back by tanjiro.

"Coming!" Y/n shouted back as she unclenched her hand, revealing deep nail marks on her palms.

Timeskip
Still narrator's view
After half an hour of convincing Inosuke that these dragons are not enemies, the emerald eyed boy calmed down just a little bit but enough to stop attacking the dragons making everyone in the room sigh in relief.

"Tohru-kun, I've been wanting to tell you this but, I'm afraid it's time to go. Shouta baby is waiting for me you know?" Lucoa said.

"I agree. I promised Takiya that I will go with him to an event. I must prepare for it." Fafnir added.

"An event? Can I come too?" Y/n asked.

"...Tomorrow. You can come tomorrow." The black haired male said with a small blush as y/n cheered happily.

"Well I don't have any plans so-" elma started only to be cut off by a salty tohru.

"Leave." Tohru commanded as a dark aura surrounded her.

"But-"

"I'll give you this bag of bread, now go fetch!" Tohru said while opening a portal to another world and tossing an unopened bag of fresh mini croissants.

"How dare you! You are being highly disrespectful and w-woah!" Elma shouted although she got cut off by tohru making the same portal but below elma's feet.

"Well that took care of her I guess." Tohru said while dusting her hands.

"That wasn't very nice Tohru-san." Tanjiro commented only to be completely ignored.
