Spoiler Alert [Demon Slayer self-insert]

Spoiler Alert: Mitsuri is cute!

Edit: I'm a dumbass and forgot to put a title...

The darling girl Mitsuri immediately looked away when her eyes met yours, covering her body with a towel. The poor girl clearly didn't expect anyone to be there, especially someone standing entirely out of the water.

"Oh hi! I had no clue you were here too Mitsuri!" You said, lying. The woman glanced your way before looking back, her blush deepening.

"I-I'm so-so sorry!" She apologized, making you tilt your head, "If I knew someone was here I wouldn't have barged in... T-They just said no one was in..."

"Don't be that way!" You said with a smile, waving her closer, "Come hang out with me!"

"A-Ah!" Mitsuri jumped before running over, a blush still encompassing her face. She quickly jumped into the spring, letting the water and steam cover her body. On the other hand, you weren't as modest, "I-It's good to see you... Y/n..."

"It's good to see you too Mitsuri!" You said with a smile, sinking into the water and sitting next to her. You kept your distance due to her seeming uncomfortable, "I've missed you so much!"

"Ah, me too," She said with a shy smile, before seemingly hyping herself up internally, "I haven't seen you or Iguro in so long, I've been lonely."

"Awh," You said with a flattered smile, happy she was thinking of you, "I've been lonely lately too, my missions have been overbearing..."

"Oh! I heard what happened!" Mitsuri looked at you in worry, "Are you alright? I heard you were injured..."

"What... Happened?" You asked before you realized what she was talking about, "The thing with upper moon 2? You heard of that?"

"Yeah! I was really worried!" Mitsuri yelled, splashing the water around her, "We had a whole meeting about it!"

"Wait what? What was the meeting about?" You asked, tilting your head slightly.

"Well, you are a pretty valuable 'asset' as Iguro says," She said, looking to the water, "It was just about making sure it doesn't happen again... I heard you were alone with him for a while."

"It's okay, Gyomei saved me in time," You smiled, looking at her sullen side profile, "I wasn't worried anyways..."

"Why? Upper moons are so strong," She said, looking close to tears, "I'm sorry I wasn't there to help..."

You smiled at Mitsuri, grabbing her hand and gripping it, "If you were there Douma wouldn't have any chance, you'd steal the show."

Mitsuri looked at you with a blush, which you assumed was mainly from the heat. She gripped your hand tighter before looking at the trees around. It was starting to get dark.

"I-I... uh..." she stuttered slightly, hiding her face from you, "I'm not that strong..."

"You totally are!" You said with a smile, scooting closer to her, "I think it makes you cool."

"Ah..." She started before smiling at you earnestly, "That makes me happy, Y/n."

You blushed brightly, turning away. You ignored the little giggle that she gave, feeling embarrassed.

"U-uh!" You started, turning to look at her again. She looked at you with her sweet smile, "Why are you here Mitsuri?"

"Oh!" She smiled wider, seemingly excited about the topic, "My sword broke! Since my sword is complicated, they need me to help them out with it. Its design is sort of jarring."

"Isn't yours the one that's all flexible?" You asked, interested in learning more about how she fights, "I bet that's hard to make."

"It sure is, they have to spend a lot of time on it," Mitsuri said, "But it's the only one that works for love breathing so it's required... Why are you here?"

"Oh, I'm here to look for a new leg. I thought if anyone could help with a prosthetic it would be the people in the swordsmith village," You said with a sigh, "It's difficult to fight with a cane all the time..."

"I'm sure it is, I just don't get how you do it!" Mitsuri said while looking at your leg stump, "It's cool how determined you are!"

"I just want to be useful," You said with a smile, "Obanai also said he'd go on a date with me once all the demons are dead so I'm working towards that!"

"Oooh!" Mitsuri said with a smile, "Maybe I should make a deal like that too, Obanai-san is so dreamy!"

"I'm sure he'd date you anyways, you're too irresistible," You teased.

"You really think so?" Mitsuri blushed, "I have a lot of flaws..."

"I don't know, I think flaws make a person a person," You said with a shrug, watching as she put her hands in her lap and pouted. You frowned, it was clear she didn't believe you, "Take me for instance, I don't know when to shut up!"

"Wha- that's not true!" She yelled outrageously, "I think you always know what to say!"

"Yeah, and what do you think your flaw is?" You asked, "That you're too strong? I personally think your strength is hot!"

"I-I don't think it's bad, I just... wish I wasn't born a girl AND strong..." She sighed, "It would be easier to find a lover that way... It feels like no one is stronger than me..."

"I think you're stunning and strong, and I know that Obanai would lick your feet if you asked him to," You said with a laugh, making her giggle along with you, "Hell, even I would."

"You're just trying to cheer me up," She laughed, her mood lightening. You let her think what she wanted to, deciding to leave the girl to whatever she wanted to do. 

The sky was getting farther down in the sky as you and Mitsuri talked about anything and everything, not even bothering to care about boundaries anymore. You leaned on Mitsuri as you ranted about disrespectful townsfolk during your missions and she spoke of the recent relationships she had heard recently.

She was sweet, but eventually, you got bored once more. So you waited till Thana had come back to finally bid her adieu. 

Luckily for you, it was confirmed that Tanjirou was in the village. You silently cheered that you were on time as you waved goodbye to Mitsuri before running down the stairs wearing your demon slayer outfit.

You were a little sour that you didn't get a fancy yukata like Mitsuri and Tanjirou, but at least you weren't running down the stairs in a towel.

You smiled when you reached the end of the stairs, slightly happy you didn't run into Genya. The poor guy was probably pretty pissed at you for beating up his oh-so-precious brother.

Just as you thought that though you turned and your eyes met with just the man you were hoping not to see. 

At least he isn't carrying his gun...

Taisho Era Secret! Genya Style!

Genya has heard what happened, but from what he hears it was a one-sided beatdown for you. He's wrong, but you aren't about to correct the guy who eats demons.
