Reincarnated into Naruto with breathing techniques.

Yui was a normal girl who grew up watching anime and being otaku, she had no parents and besides a sum of rights her family left for her to live her childhood in trouble.

One day she was run over by a truck and the next thing I knew she was a baby, yes a 3-month-old baby who was nursing at her mother, "Ready my baby, here's your milk."

Aika fed her baby who tried to resist her breast but ended up giving in after a while and sucked him hard, Yui taking advantage of the time she was feeding opened her small eyes and looked at her mother.

Aika was a pretty pretty woman, she had dark brown hair and brown eyes, her body was a little thin but nothing too exaggerated, in short she was a very pretty woman.

Finishing evaluating her mother Yui evaluated her house, it was a small house with two bedrooms and there was little furniture in the place, in her evaluation her family was poor but did not suffer from difficulties, looking at the window Yui saw that it was raining outside .

"Well it looks like I've reincarnated, now the question is where is my cheat?" She mentally said like she expected something and actually something happened, Yui's eyes widened for a moment before a great deal of pain attacked her head and she started screaming like a baby.

"Oh my god what's going on!" Her mother screamed in fright when her daughter started screaming and tried to calm her down but it was in vain, at that time Yui was receiving memories of Demon Slayer's breathing techniques and a brief introduction to her current situation.

She was in Naruto's world in the Mist Village just before the bloody mist rumors started, her father was an Uchiha spy who slept with her mother for one night before being captured and killed, her mother didn't know about it and continued to seeks him out to tell him about the fact that she was pregnant but she never found him.

Who takes care of her family is her uncle Hiroki who is a Genin in the village and uses his salary to take care of us, she also got the knowledge of Demon slayer breaths but they not only strengthen her physical strength.

The breath Yui uses will change her Chakra, if she uses her Chakra fire breath it will go to the fire attribute and when she uses a blow it will release flames, the same goes for the other breaths.

The only downside to this is that she can't use ninjutsu, Taijutsu or anything else and will have to make do with what she has, and probably pity the being who sent her here she also knows how to forge a special sword that can change shape.

However, she needs to grow up first and after a forge in addition to the materials for that, while the explanation happened half an hour passed and Aika was already almost shed tears in despair seeing her daughter crying in pain.

However when she was about to go get a doctor Yui's screams subsided and she fell asleep from exhaustion, "Glad you almost killed my heart!" Aika sighed and wrapped Yui in a cloth.

The next day.

Yui slowly opened her eyes and felt a warmth from the sun and a cool air on her skin. "Well it looks like this will be my good morning from now on." She said mentally and began to analyze her situation calmly.

From a certain point of view she was totally screwed, the third big ninja war had started in 8 years and that's not taking away the fact of all the bad things that happened here in the village of fog, besides the fact that Obito would control the village more afternoon and everything.

"A sane person would choose to leave this place immediately but I need something here before I leave." One of the ingredients for forging the shape-shifting sword is one of the Swords of Mist that you get by becoming one of the 7 swordsmen of mist.

However only capable and talented ninja can achieve this position, Yui lightly formed a plan for the future before turning back to the present and starting to get excited at this point, she would use the legendary breath.

Yui took a deep breath and controlled it lightly before using Sun Breath right away which proved to be a mistake, "Argh!" Yui gave a small cry of pain and the veins in her tiny body swelled and her small Chakra turned violent as trying to change to the nature of the sun.

However it only lasted a moment before it went back to normal and left an all red Yui almost losing consciousness behind, "My god that was dangerous!" She mentally exclaimed and felt her whole body burning.

"It looks like I won't be able to use Sun breath until I have a stronger body and bigger Chakra reserve." Learning from her previous mistake Yui this time used water breath as a test.

Unlike sun breathing, water breathing was much less violent and calm but Yui could only maintain this state for a few seconds before she started to feel pain all over her body again and then she shut down.

Yui repeated breathing training for a while until she couldn't take it and then switched to Chakra training, she had some difficulty feeling the Crakra in her body but after a while she could feel it.

"So this is the legendary Chakra!" Yui muttered mentally and stared fascinated at the energy in her body before trying to make it circulate however she found it surprisingly difficult.

No matter how hard she tried it felt like a square iron ball inside a swamp that refuses to move no matter how hard she tried, "Let's move, Move!" Yui broke out in a sweat as she tried. make her Chakra move and when he finally showed a small reaction she lost control of it and returned to her normal state.

"This is very difficult but looking on the bright side it means I have a big reserve of Crakra I think…" Despite the difficulties Yui didn't lose heart and went back to training, she knew that if she didn't try hard she wouldn't survive in this world.

When Aika came home later she found her baby covered in sweat sleeping peacefully and wondered if she was sick, "I think I should take her to the doctor tomorrow." Aika muttered as she looked worriedly at her baby.
