Stories I have written but most likely not finish

Demon Slayer/ Kimetsu no Yaiba (KnY)

As Tanjiro accepted the challenge he notices three girls standing to each other. They all were around the same height. One of them has very light blonde hair while wearing a simple fox mask. She was wearing a white kimono with pale orange at the end of her sleeves and her ribbon and a pale yellow at the bottom of her kimono. She had two katanas with the sword guards criss-cross on her back. Her wooden sandals had a pale red cloth on them. The second girl he notices had grey-white hair, storm grey eyes and had a cloud hair clip. The twins announced that the challenge has now started. he couldn't get much on the last girl as he knows that she looks a lot like him but having a different hairstyle.

Timeskip to the Mt. Nagumo

As Tanjiro was fighting the upper moon spider demon he started to lose hope. Until he hears a voice shouting. "Breath of the Clouds Fourth Form: Overcast Fog" Tanjiro notice that it was one of the three girls he saw from the previous challenge he took. He then woke up tied up and saw the hashiras together but he noticed that the three girls were also there. Sanemi decided to take off the mysterious girl's mask. The other two girls noticed and told him to stop, while the rest of the hashiras were ready to stop him. "Oh come on guys I just want to see why does Zekuna use a mask all the time" "Sanemi listen there's a reason——" One of the two girls were cut off as he ripped Zekuna's mask off her face as Zekuna stumbled back covering her face with her sleeves. "Sanemi, give me my mask back" Zekuna's voice was muffled as he was baffled at her voice. One of the two girls gave Zekuna back her mask. "Thank you, Nebula" "No problem," Nebula said while giving a closed-eyed smile. The last girl sighed and walk towards her while giving a small smile. Zekuna knew the smile and reluctantly took her mask off. Sanemi saw her face and now realise why she uses a mask all the time while he and the rest of the hashiras can't help but blush at her appearance.

Timeskip to where they are at the butterfly mansion

Tanjiro sweatdropped at the scene in front of him as he noticed three new people with the three girls. He can't help but blush at Zekuna's appearance. Her bangs were swept to the right and two blue diamonds and a small stick in between the diamonds held her bangs in place. She had light blue eyes with a darker shade of blue as her pupil and her eyes resemble a fox. Tanjiro then notices that three of the girls looked exactly like him, Zenitsu and Inosuke. "Hey, you doing ok?" Zekuna's voice had a light tone as she turns to three of the girls. "I like to introduce you to my friends" She walked towards the grey-white haired girl. "This is Nebula" "Hi!" She smiles waving at him. "Her Breathing style is Cloud breathing" She moved on to a girl who looks like a splitting image of him as his eyes widen. "Well, I see you are surprised at how Ignis looks like a splitting image of you" Ignis laughed while she waved. She then wraps her arms around two other girls who looks like a splitting image of Zenitsu and Inosuke but are still different. "These are Electra and Silva" She then stop and gestured to a boy who looks like a splitting image of Nezuko but a lot like he can turn from demon to human and so forth. "And this is Kaen" "Hey." He waved. "So, now that we have met, I'm guessing you are Tanjiro Kamado, Zenitsu Agatsuma, Inosuke Hashiraba, and Nezuko Kamado correct?" She looks at Tanjiro directly at his eyes as he was shocked at how she was able to name them all.

Timeskip to them training

After the training Shinobu gave them, Zekuna went to check on them. "Can I ask what are all of your breathing styles" she chuckled before answering him. "Why of course, you see since Ignis, Electra and Silva are splitting images of you three they have the same breathing styles as you but different." "How about Kaen?" "Ah him..." She rubs the back of her neck. "Same applies to him, he can revert from demon to human and have the same demon blood art as your sister, Nezuko." Tanjiro's eyes widen as he went closer to her. "How?" She gave him a sad smile "Unfortunately, I can't give you the answer" Kaen wrap his arm around her rubbing her shoulder comfortingly while she laid her head on his shoulder
