Yandere Yoriichi x female reader
Yoriichi took every palladium for [Y/N] and their child. When he’s gone a long time helping the Demon Slayer Corps Yoriichi buys wisteria powder for her and even offered to hire a bodyguard. They’ve been married for two years and everyday [Y/N] is happy and thankful. Sure, she’d love if Yoriichi could stay home more but his work is important. The wedding ring is enough; it brings heartwarming memories until she can see Yoriichi again.
It’s a beautiful day. Taking a bag of wisteria, she waddles into warm sunlight and fresh air. [Y/N] loves visiting shops in town. The people are kindhearted. But now they are mournfully silent.
Waiting in line at her favorite food stand [Y/N] overhears apprehensive gossip.
“Someone in town died yesterday.”
“Was it a demon?”
“I think it was a human. But the Demon Slayer Corps sent out some swordsmen to investigate.”
“You think there’s a murderer around?”
“How’d they die?”
[Y/N] wanted to ignore the icy fear latching to her bones but she kept listening as she shuffled forward. Maybe there’s information she could use to avoid encountering the murderer.
“Split in half. Burned.”
A man snorted. “If they were burned then it was probably a terrible accident.”
“Then how do you explain how they were split in half?” An old lady asked.
“Yeah, a demon would’ve eaten them.”
“The Demon Slayer Corps said it was a merchant. They found his bags and broken earthenware on the road.”
Sitting on a bench [Y/N] ate her food but a delicious meal couldn’t distract her. There’s only one merchant who visited town selling earthenware. And she bought something from him yesterday.
Mr. Agawa is her neighbor. An old man who paid [Y/N] to clean his house and water a garden. Her husband always sent money from his job as a demon slayer but they now have their child to think about. What if Yoriichi got injured and couldn’t work? What if they got sick? What if they needed extra supplies? So every day, [Y/N] walked to Mr. Agawa’s house to work.
The old man has many scars on his face –conveying that he has survived many battles. But he’s unlike his rugged exterior, sweet and generous. He sits on the porch saturated in sunlight and often talks about his brother who worked as a sailor.
Looking up she sees a bird circling. Yoriichi’s bird!
“Letter for [Y/N]! Letter for [Y/N]!”
She caught a parchment and unrolled it. Her fear vanished as she read the letter. Yoriichi will be home for a month!
Mr. Agawa stood up with a cane, slowly limped over, and gave [Y/N] money.
She looked at him in shock. “I haven’t harvested the vegetables yet-”
He waved his hand and smiled. “Go home. You’ve been separated from your husband long enough.”
[Y/N] hugged him. “Thank you Mr. Agawa!”
It’s been ages since she’s cooked for another person. Outside she hears footsteps marching up the road to their house. She runs to Yoriichi and hugs him. He’s silent as usual but his eyes gleam happily.
[Y/N] sat across from her husband and talked about how the days have been peaceful and boring. Well. Until today. “People are saying there’s a murderer in town. I’m happy you’re here. I missed you. I feel safe from anything when you’re with me,” she laughed.
Tomorrow, [Y/N] started walking to their neighbors and hummed a tune. Yoriichi stopped her. He looked at his wife questioningly, seeing a basket in her hands. “Where are you going? To Mr. Agawa’s?”
“Yes. I saved a hot meal for him since I made too much food for breakfast. He doesn’t leave his house much.”
Yoriichi slung the pack over his shoulder. “I’ll take it to him. Can you go into town and get me some things?”
“Sure.” She could go buy tickets too. There’s a play at a theater. It’d be fun to go see it with Yoriichi.
On the way back there’s a river that stretches across the outskirts of town. Small glimmering fish swim between large stones. In the distance is a dense forest. [Y/N] stands on the bridge dropping her bags for a minute to rest. Wind flew by her face carrying a scent of flowers and sereneness. Shrubbery moved. She expected to see an animal. But it’s a man –Mr. Agawa!
Terror shines in his eyes. Throwing his broken cane Mr. Agawa runs. A long wound is across his chest. Fire coils around his leg as he screams. He falls and scrambled on all four limbs to crawl away. Who’s chasing him?
Yoriichi emerges from the woods. His beautiful eyes glint dangerously as he briskly walks up to his opponent.
Mr. Agawa holds his wound. He’ll bleed out soon and his scorched leg made it impossible to run away. His frown turned into a bitter smile. “To die by a demon slayer…not the way I thought I’d go. You…are worse than any enemy or demon I’ve faced.”
A sword blade severs his head from his neck.
The demon slayer picks up Mr. Agawa and put him over his shoulders. Yoriichi’s gaze sweeps the horizon –and he freezes when he sees his wife.
“Yoriichi?” She gripped the bridge railing to steady herself. Heart pounding, [Y/N] wondered if running would really help. Mr. Agawa wasn’t a demon. He wouldn’t be in the sun. Why did Yoriichi kill him?
She abandoned her shopping bags and ran. Her legs, knees, and arms ached as she desperately tried to sprint to the town. Crying, tears blurred her vision.
Crackling flames shot past and surrounded her. Yoriichi, calm as ever, walks up to his wife and offers a hand. “Come home.”
“What?” Intense heat and dark smoke swirl over them –a signal of looming death. “No,” [Y/N]’s [color] eyes stare at the sword. Blobs of blood dripped from the metal. “I won’t.”
The smoke is scratching her throat. How would she escape? Nobody can defeat Yoriichi in battle. Even the strongest and smartest demons are scared of him.
Patiently he waited. Even as fire trapped them. Tears sting [Y/N]’s eyes and her hair is waving from roaring winds. “Why’d you kill Mr. Agawa?! You’re a demon slayer! Aren’t they about honor and justice?!”
Heartbreak is clear in Yoriichi’s voice. “I’m still an honorable demon slayer. You were in danger.”
“I came home earlier. Before I sent that letter. Did you know that merchant you bought earthenware from was a demon?”
[Y/N] is shocked.
“He had slowly gained a tolerance to wisteria powder. I was surprised that he didn’t kidnap you. He wore a disguise, said he actually liked humans. Wanted to learn more about them and their society. Made earthenware because he fell in love with the arts. But a demon is a demon. So I killed him.”
Sympathy grabbed [Y/N]’s heart. It’s heartbreaking! The merchant was a demon but he didn’t deserve to be killed. If he had wanted to be friends with humankind, he should’ve been left alone, unlike the other violent demons that the demon slayers attack.
Yoriichi shook his head and smiled. “You’re sweet, [Y/N]. That’s why I love you.”
Frowning she spat, “What about Mr. Agawa?!”
“He was a violent outlaw. A bandit. He stole from travelers who hardly had anything. Society doesn’t need bandits like him. And I couldn’t risk you getting hurt.”
“Now,” Yoriichi reached out for her arm. “Let’s go home.”
She never doubted her husband. Yoriichi always told the truth. But he’s still a murderer. “No! I love you, Yoriichi. But you’re a murderer. I-”
His grip is intimidating and strong like stone. “I can’t let you go. You won’t be safe without me.” So the pair leaves the fierce firestorm and walk back to their home. [Y/N] felt her feet drag as she cried, her mind panicked as she unsuccessfully tried to wrench herself free.
