Kny New AU?

Intro So moon pies, honestly I have no idea what an AU is 😭 EXPLAINNN also this is kinda like that old movie a diary of a princess but…X kny! So your a normal person your a orphanish? Chores person, your pretty cute too, All though Long ago (⚠️FAKE⚠️I made it up) Muzan had a child with a goddess, That he divorced due to her finding out he’s a demon! They had YOU! You have powers and your royalty. You don’t know you have powers YET. The hashira found out sense Master Kagaya told them he said to find you and keep you down in the dungeon. Or possibly killed. But they had other ideas. People: Muichiro Shinobu Giyuu Mitsuri Sanemi Obanai Kanae(she alive) Gyomei Tengen Rengoku. For making this more realistic use Japanese words like for bye or goodbye say: Sayonara. Or Oh my or Oh oh oh say: Ara Ara and for hello say: kon'nichiwa. Or for I speak say: Moshi Moshi. And for not understanding say: Eh? And for Kawaii just say: Kya or Kyah! Idk I just made that one up 😭 idk if it’s right. And for good say: Umai So say: Hello: kon'nichiwa Goodbye/bye: Sayonara Oh my/Oh oh oh: Ara Ara I speak: Moshi Moshi Not understanding something they say: Eh? Kawaii: Kyah!/Kya!
