Demon Slayer OneShots

Uzui Tengen

The feral Wind Hashira and the calm Moon Hashira - siblings, born exactly 12 months apart. While he was feared by many, especially the lower ranked demon slayers, she was adored by many.

They had lost their family minus their younger brother Genya at a young age - and even then, the two only ever had each other. He wanted revenge for his family's death, she wanted to keep people from going through the same things she did.

She even felt deep sympathy for the young Kamado boy - with his entire family except for his younger sister dying, she knew how he felt and why he wanted to protect her - other than her brother.

Sanemi didn't get Tanjiro's intentions at all.
"Kibutsuji has hired people to follow Tanjiro. Maybe he just wants to silence him. But since this is the first time we get a little piece of information, I don't want to let go. Something could happen with Nezuko, that Kibutsuji didn't expect. Do you understand?"

"No, Oyakata-sama, I don't understand you. We can let a human live, but a demon must not! You know our emotions when we throw ourselves into battle and what prices we had to pay so far. I can't accept this!" Sanemi growled.

He drew his nichirin blade and cut his arm, some of his blood dripping on the courtyard, making y/n's eyes widen. "Oyakata-sama, I will show you that every demon is evil!" Sanemi continued.

"Sanemi, what are you planning?" Oyakata-sama asked. "Demon, here's your food! Take a bite!" he said, holding his arm over the box Nezuko was im and placing his foot on it.

"Stop struggling! Show us your true nature and then I will rip you to shreds!" Sanemi smiled like a maniac. "Shinazugawa, it won't work in the sun. The demon will only come out in the shadow." Obanai reminded.

"Oyakata-sama, I apologize, but I will continue." the feral Wind Hashira turned to the head of the demon slayer corps, before throwing the box in the shade on the patio.

He stabbed the box yet again, making Tanjiro scream at him. Obanai slammed his elbow down on Tanjiro's back, effectively keeping him from standing up.

"Come on out, demon! Here's your beloved, human blood!" Sanemi said. Y/n knew what Sanemi was thinking. His blood was that of a marechi, a special type of blood that's extremely mouth-watering to demons.

Sanemi opened the box with his nichirin blade, Nezuko slowly standing up and looking at the blood that was dripping from his arm. Tanjiro was able to get free from Obanai's grip after Shinobu had warned him about using a breathing technique while his lungs were under pressure.

He ran up to the patio, but was held back by a hand on his shoulder. "Please, don't step closer." y/n said and Tanjiro's eyes widened at her kind smell.

She climbed up on the patio and walked up to Sanemi, slapping the back of his head before pulling out a bandage that she always kept in her uniform in case she was injured or Sanemi injured himself on purpose.

"Shinazugawa-san, please refrain from hurting Nezuko." she mumbled, Sanemi's eyes widening at the fact that she had used his last name instead of his first name or a nickname.

Nezuko calmed down at the arrival of the Moon Hashira, slinging her arms around the older girl's waist, who patted her head. Uzui watched the interaction with adoration and curiosity.

The Hashira had spiked his interest. After his daughter had explained to him what happened, Oyakata-sama apologized to the Moon Hashira for having to intervene and told the Hashira that now, it was proven that Nezuko wouldn't hurt anyone.

After the meeting, Tengen walked up to the calm Moon Hashira, truly impressed by how she had handled the situation. "Shinazugawa-san, it's a pleasure to meet you! You look flamboyantly beautiful." he said.

She turned to face him, staring up at him and smiling. "It's a pleasure to meet you as well, Uzui-sama. Sanemi has told me a lot about you." she spoke.

"Only good things, I hope." Tengen answered, grinning at the way she was smiling sheepishly. "Let's change the topic by saying he talks about you." she laughed.

"Well, would you want to go eat some ramen with me?" He asked, outstretching his arm so she could place hers around his. "I'd love to." she smiled, placing her arm around his.

A few weeks later, Tengen had come to pick
y/n up for a date, their first official one. Luckily, Sanemi was on a mission, so the only one present was y/n's little brother, Genya.

He was a lot more relaxed when it came to her dating someone. He thought she was the person that deserved to find love and happiness the most, for she was the one that had to handle all of his and Sanemi's mood swings along with being a Hashira as well.

When Sanemi came home and asked where his younger sister was, Genya had no choice but to tell him. The feral Wind Hashira, living up to his name, stormed out of the house to search for his sister and comrade.

He didn't see them walking down the road towards her Estate from the opposite direction. Reaching her home, he pulled her in a kiss, placing his hands on her cheeks.

"I'm glad you're officially my girlfriend now." Tengen breathed. "Me too." she smiled, kissing him again.

"Uzui! Better get your ass away! I will rip you to shreds!"
