Everyone knows that Muichiro had a twin brother, Yuichiro. But what If he had an older sister who was taken away when he was seven. His sister's name is Y/N. Y/N was trained as a demon slayer during her time away from her family. Now, 4 years later...
Hello! This is the author! This is my first Demon Slayer fanfic. The updates will unfortunately be slow so I apologize. Just so this story makes a bit more sense, let me write a short section about Y/N's background.
Y/N Tokito is 16 at the beginning of the story, which is when Muichiro is 11. When Y/N was 12, her family was struggling and they needed money. One day, A man had been passing by saw Y/N and offered to buy her. Her family, despite being poor and about to starve, rejected his offer. Y/N saw all of this and said she would except the offer. Her family was horrified and begged her to stay. But they couldn't change her mind. The man gave the Tokito family the money and took Y/N. Everything else that happened in Muichiro's life happened. Meanwhile, the man tried to train Y/N in mist breathing, but it wouldn't work for her. She had all the potential, but mist breathing just didn't suit her. So Y/N and her master start to develop another breathing style: Ice Breathing.
1st Form, Frigid Air: The air surrounding the user and their sword gets cold, and the user moves so fast the demon doesn't realize their head is getting cut off until they feel a sharp pain.
2nd Form, Icicle Laceration: The user swings their sword in a grid-like pattern.
3rd Form, Frosted Slash: As the user swings their sword in multiple, frost that spreads covers the user's sword and spreads to the enemy.
4th Form, Freezing Mist: This move came from mist breathing. Any moisture that is in the air freezes and creates a mist that hides the swordsman. The user of this technique is temporarily hidden, moving at an incredible speed. They perform slashes from multiple directions.
5th Form, Light Snow After A Blizzard: This move is peaceful. The demon feels no pain at all. As the slayer gracefully moves, small snowflakes trail after them.
6th Form, Snowy Slice: The slayer moves gracefully as they slice once horizontally.
(A/N I hope to come up with more forms, but at the moment, this is the best I can do.)
Y/N continued to train until she was able to go to Final Selection. She passes and becomes a demon slayer at the age of 14. By the time she is 15, she manages to defeat a lower moon. Now, she is known as the Ice Hashira.
Now, me being me, I'm gonna write Y/N's relationship with the other Hashira.
Gyomei Himejima: They don't talk a lot, but when they do, they talk about how much they love children.
Kanae Kocho: They get along really well. Y/N tends to visit Kanae a lot because she gets freezer burn from her breathing technique. Y/N ships Kanae with Sanemi.
Sanemi Shinazugawa: They get into arguments a lot, but when they're not arguing, they get along.
Kanroji Mitsuri: Besties <3
Obanai Iguro: They never talk. But in the future, after Mitsuri joins, they become friends.
Kyojuro Regoku: They act like siblings.
Uzui Tengen: They're flamboyant together. Y/N doesn't really like certain parts of Uzui's personality, but when he isn't asking her to be is 4th wife, they get along really well.
Giyuu Tomioka: They talk. And they may like each other.
Now, what does Y/N look like?
Hair color: Black that fades into a light glacier blue.
Eye color: Teal
Haori:

Height: 165.1 cm (5'5)
Y/N's Personality: Tends to be chill, but when around energetic people, she gets really hyped. You NEVER want to make Y/N mad. Like, Kanae, she hopes that one day, humans and demons can be friends (I forgot to mention, Kanae ends up dying in the infinity palace with Shinobu). Y/N is sweet and is very fond of kids.
Finally! I'm done writing this! It took me so long. Unfortunately, I hope y'all read all of that 'cause the story's gonna be confusing if you didn't. Anyway, I hope you all have a nice night/day/afternoon/morning!
