Demon slayer prompts 4
1. Giyuu has lost his memories after taking a blow to the head. When he wakes up, Tengen is there with Muichiro and he convinces the water pillar that Sanemi is his husband and Muichiro is thier adopted son.
The mist hashira originally went along with it because he was bribed but stuck with it when Giyuu started spoiling him with food and attention.
Everyone is shocked when Mr Tomioka started behaving differently. He was soft, sweet and very shy but didn't hesitate to smile and chat politely with anyone who approached him. It was a complete 180 and most of the other hashira thought it was better to just never let him remember. Some for thier own benefit and others for the belief that whatever traumatized Giyuu this bad to make him as cold as he was before probably wasn't worth reliving.
Sanemi returns from a mission and is informed of his pretend marrage and family. Needless to say he promptly crashes out and heads to the water estate to find Giyuu and Muichiro there and he rips them a new one.
Giyuu, who has returned to the tearful state of his youth, starts crying and begging for forgiveness, saying he doesn't want a divorce and whatever he did wrong, he would try to do better.
Muichiro gives Sanemi the coldest look the wind hashira had ever seen on the kid, "Apologize to mother. Now."
Sanemi complied...if just to avoid whatever horrors the gremlin could cook up.
Things take a turn when Giyuus old sensei shows up prepared to murder Sanemi for marrying his son student without permission. Tengen got half way through his explanation before Urokodaki decided these heathens were trying to take advantage of Giyuu and they must both parish.
He's excited about having a grandson though.
(Cut to Muichiro chilling with his head in Giyuus lap while being hand fed grapes)
2. Inosuke found a strange gaudy looking necklace hidden in a chest behind a waterfall and decided he needed to show it off to everyone.
This turned out to be a bad idea as when he was running around trying to find Tanjiro, he tripped, and the necklace flew through the air and landed in front of Sanemi, Giyuu and Kyojuro. The necklace let out a bright flash, and suddenly it-and them - where gone.
The next thing the trio knows they are in a futuristic version of Japan, and they are more of less accosted by a talent scout. After learning the demon slayer core was disbanded long ago after Muzans defeat and knowing what else to do, they become a famous boy band.
Turns out all those breathing and sword fighting techniques translate well into singing and dancing. Turns out Tengen had daydreamed about something like this for years, and they had songs and dances memorized for all of the hashira.
Though all is not well as the longer they stay in this era, the more demons seem to fade in and out of existence as if time is correcting itself. The necklace shows no sign of its previous powers. Will they be able to return home before its too late?
(Tengen is going to be sooo jealous. This au works so well with DC because if they bring Constantine back with them, Muzon is screwed and most people will get a happy ending)
3. Sanemi refused to believe in ghosts.
These kids were just regular brats out who happened to be very slippery. That being said, when he inevitably caught those two kids, he was going to take them down to the station and take their masks off himself before he gave them the scolding of a lifetime.
Once that was done, he was going to make them call their parents down to the station, and then he was going to rip them a new one entirely. Safe or not, this was still a city and these were still kids out and about way past curfew. That's not counting the fact they've been spotted riding on the tops of BUSSES and doing other reckless stunts.
There's no such things as ghosts. Right?
Aka ghost children au where the legend about a bunch of dead child warriors wearing fox masks gaurd the nearby mountain and a secret sword technique passed down through the ages. Police officer Sanami calls bs and is taunted played with endlessly by Sabito and Giyuu who think this is hilarious.
4. "Mmph!" Genya stared at Giyuu in horror as he kept the gas mask pressed to his subordinates face, his own broken one dangled limply from between his fingers from his earlier carelessness.
"Whatever you do," he said, blue eyes blazing by into Genyas own assweat trickled down the youngers brow, "Dont take off your mask. That's an order." The water Hasira quickly turned away and inhaled deeply as the sickly yellow clouds of fear toxin closed in around them.
Then he was off. The strangest part about all of this is that the demon had all ready been slain, so why was its blood demon art still activating? And why wasn't its body dissolving?
He could ask questions later, for now he needed to help Tanjiro and the others destroy those spore pod things before too many civilians were infected! The water hashira had been so kind to put himself at risk to make sure he was safe so he would do his best not to let him down!

5. Time travel au where Giyuu wakes up in his old body while he was being transported to the asylum after his sisters death.
Needless to say, he just escaped again and lived off the land as he traveled from town to town, selling whatever he didn't eat. Being a weak child again was much harder than he thought. Most of his time was spent trying to survive, so he didn't have much time for training. Luckily, he had gotten an idea when he saw an old set of child paints. Seeing his staring, the old lady handed it to him and told him he could have it. He thanked her quickly and fled before she could start asking questions, like, "Why are you dressed in rags?" or "Where are your parents?"
His plan was simple. He was going to paint little things around the town he had met Sabito and their teacher. Urokodaki and Sabitos masks were painted in hidden places, blue spider lillys were painted out in the open, images of demon slayers with their crows were painted on the sides of buildings and the kocko sisters hair clips were painted on windows.
Needless to say, this grabbed their attention pretty fast, and Urokodaki tracked Giyuu down to a little run-down hut...only to see a painted wall mural of Sabito fighting the hand demon as his sword breaks.
"The neck is a trap." Giyuu says from behind them, startling them both.
"What do you mean?" Sabito asked, more than a little freaked out.
Giyuu just stared at him for a moment with his eerily calm eyes, eyes that he knows many people have called 'dead' and 'creepy', something he's now using to his advantage, "Its neck is hardened so if you cut there your sword will break. You have to cut somewhere else."
"What of the blue spider lillies? Have you seen them?"
Giyuu looked up into the face of that familiar tengu mask, basking its familiarity for a moment before he lied through his teeth. "Not in person. I dream of them every spring. Sometimes, there's a woman in these dreams. She's gathering them."
Urokodaki and Sabito share a look before turning back to the strange child, "What does she look like?" "Does she say anything?" They ask at the same time.
Giyuu tugs his sisters red hiori around him tighter, chilled by the snowy winds outside the hut, "She wears a purple and white checkered obi and a white apron. She talks to herself when she's gathered enough, mentioning soup or medicine for her family." Giyuu stares up at Urokodaki in that one particular way he knows makes it feel like he's staring directly into your soul, "Are you sick? Is that why you want it?"
The tongue man laughed softly, "So you're not all knowing after all?"
The child shook his head, "I dream. That's all."
He was soon forced to eat those words when he took Urokodakis outstretched hand and gasped, his mind becoming flooded with images of him slaying demons throughout the years.
He yanded his hand back, staring at it like it betrayed him, "...what?"

Aka Time Traveler Tomioka fakes being a clairvoyant so that people will believe him only for the gods to decide to make him a real one.
