Dawning on new roles!

Demon Slayer SWAP AU

After her older brother's ankle is sprained, Nezuko Kamado manages to convince him for her to go sell charcoal on his behalf. Sadly, she returns home to find her family massacred and her brother, Tanjiro, turned into a monster. Now she embarks on a journey to cure him and stop the demon who changed her life by becoming a demon slayer!

Once upon a dark moon, a lonesome swordsman encountered a phantom of the past. Kokushibo, the fallen samurai turned demon, met a young boy by the name of Tanjiro Kamado, an almost doppelganger of his long deceased twin brother he loathed. Subsiding his hatred, the strongest Upper Moon of the Twelve Kizuki decided to conquer his emotions -the complex he still has with his prodigious twin- via exposure therapy with the child.

In the secluded temple grounds of a cult known as Paradise Faith, the leader and prophet of the twisted religion, though hollow inside, grows curious at one of his followers and her child. Douma, Second highest-ranking Upper Moon serving under the Demon King, begins to lern about Kotoha Hashibira and her piglet, Inosuke, fiding his cold heart to kindle ever so slightly.

In the bustling Red-Light Entertainment District of Yoshiwara, a highly renowned courtesan -an oiran- known as Warabihime prowls the currupt district as her true self, Daki, a vain demon, alongside her brother, Gyutaro. In one of her sporadic hunts, she encounters a street rat whose conditions and appearance hearkens back to memories long forgotten, so, conflicted, she fostered the homeless child named Zenitsu.

These coincidental encounters lead to drastic changes in destiny, but will it be for the good of humanity or for its detriment?

 A long time ago, Mitsuri was energetic an energetic girl whose dream was to find love and get married. Unfortunately, most suitors found her outgoing personality to be immature and not proper for a lady. The only person who ever showed interest in her true self was a mysterious boy with heterochromia.

 The boy's (Obanai's) life was riddled with trauma, his mother and cousins would constantly mistreat and insult him, causing him to develop a strong inferiority complex. One day he ran away from home and met an optimistic girl by the name of Mitsuri, who he instantly became infatuated by.

 The two became friends and slowly developed feelings for each other, however their difference in status prevented them from being in love. time and time again Obanai would ran away from home to meet Mitsuri, unbothered by the punishments his mother would give him once he returned.

From here on I have less written down, but my rough idea is to have uit so, one day, Obanai's family discovered where he ran to, robbing and murdering Mitsuri's parents and leaving the girl fatally wounded. He retaliates by killing his mother and cousins.

For context, this is for a very odd alternate universe I'm thinking of developing where demons are a sentient carnivorous subspecies of humans that are a staple of the world. Essentially, demons are a natural uccurring phenomena that certain individuals are predisposed to become.

 Virtually indistinguishable at birth to humans, demons are thought to be a genetic mutation that develops its phenotypes as an individual ages. They have the same abilities and weaknesses as in canon.

They were, understandably, ostracized from society until a social pact was made that made men and demon alike exist in tandem in one society. Demons would stop hunting humans indiscriminately and, in exchange, humanity would provide regulated, sustainable sources of nourishment.

Tensions remain to contemporary times, but demons now live among humans, predator and prey sharing a fickle equilibrium.

I've been toying around with my own take at a "Ship Swap" AU. Gotta say, on paper it sounds ver nice, but the execution is proving to be tricky... Let me know your thoughts!

Zenitsu Love Breather: Mitsuri's Tsuguko! AU

A spontaneous AU that popped in my brain. Basically it's what I laid out, Mitsuri taking the would-be thunder breather under her wing, becoming another little brother to her. I imagine Zenitsu would be very spoiled by her, but her training would be super duper hard to compensate!

Actually, I meant to have mention it originally but changed for the sake of pacing, but the demons Tanjuro/Yoriichi fought in the meantime between the Kidnappers' bog and Tsuzumi mansion were Susamaru and Yahaba.

Oh man! What a good ask! Firstly, thank you for liking my fic thus far, I promise new chapters will release soon, I got the first part of the next arc written pretty much already, just need to review it and add a couple details...

... I should have made Muichiro be Kris in my UNNAMED DELTARUNE x KNY AU istead of Rui...

He has more connections with the rest of the cast, like Gyomei (who is King), Gyokko (who is Tenna). Plus we could have one of the Tsugikuni twins be the Roaring Knight too...
