Breath of the Sun

The next morning Kenshin woke up to find two people near him, his father and mother. His mother was sleeping by his side on the bed and his father was sitting on a chair near the bed. Kenshin also saw dark circles below their eyes.

"They must have stayed awake late. It's my fault to get suddenly unconscious", thought Kenshin. He was happy and slightly sad, happy because he now have such a caring family and sad as it was his fault they stayed awake late.

"Oh, why did I get unconscious like that before", thought Kenshin when he remembered what happened last night.

"There are some memories in my head. Oh these look like memories of a technique or something. Is this my gift for being reborn like in the novels. Oh my god this technique is "Breath of the Sun" from Kimetsu no Yaiba.

It is said to be the most powerful of them all. Wow this is a nice gift. Though there are many powerful people in this world. If I use it to full extent and use chakra to enhance it. It will be an OP technique", thought Kenshin while smiling.

Hearing some disturbance Kenshin's parents woke up and find that Kenshin was smiling. They both sighed in relief as nothing happened to their child.

"Oh my baby, what are you smiling for. Let mother give you a kiss", saying that Minami kissed Kenshin on his cheeks which brought him out of his thoughts. Kenshin looked at them and giggled.

Seeing his smile, both his father and mother were very happy. Soon after that a nurse came to check Kenshin. After saying that he was fine, Kenshin's parents became happy.

After that his father went to duty. Kenshin found that his father was in the Police Force which is under the Uchiha's.

Some times later it was time for him to eat or more specifically drink milk from his mother's breast. Kenshin found it difficult at first as he was mentally 40 years old. But after some time Kenshin accepted his fate as he would start his life anew.

After feeding Kenshin, his mother went to sleep as she was tired from both child birth as well as waking late night.

It was perfect moment for Kenshin to start practicing breathing technique of "Breath of the Sun". Kenshin had skim through the technique and found that there two parts, one is breathing technique and other is kata's or different form of sword technique.

Breathing technique was divided into two parts one is basic and other is advanced. Basic one can be done regularly to improve physique while advanced one will give explosive power when used with the Sword techniques.

Then the sword technique was divided into 12 kata's.

1- Peaceful Dawn

2- Rising Sun

3- Morning Heat

4- Blazing Sun

5- Burning Sky

6- Afternoon Thunder

7- Flaming Shower

8- Chaotic Dusk

9- Star Gazing

10- Flame Phoenix

11- Flame Dragon

12- Annihilating Sun

Kenshin didn't know the level of Kenjutsu this world has as it is not shown often. He is sure that if he train these techniques he will definitely be a Kenjutsu master.

After that Kenshin calmed down and decided to start the basic version of breathing technique. While in sleeping position Kenshin started to breathe as mentioned in the technique.

Just after 2 minutes, Kenshin's lungs felt like it was on fire and couldn't take it more, so he decided to stop. After stopping Kenshin felt a little bit stronger. His eyes shone ashe knew this technique will help improve his physical strength a lot.

Like this Kenshin repeated this every 10 minutes and by the end of the night he was able to do the breathing technique for 3 minutes. It was nighttime and Kenshin was too excited to sleep so he decided to do meditation to check his Chakra and see if he can control it.

After spending for 10 minutes, Kenshin found his chara but it was too low. Kenshin then decided to revolve this chakra in his chakra system. And after a few minutes Kenshin got tired but still was happy with his progress.

Like this few days passed by and Kenshin would do breathing technique in the day and meditate to increase chakra and it's control at night. After that Kenshin's mother got discharged from the hospital and they went back to their home. Their home was not that far from hospital as it took 10 minutes of walking.

Kenshin then saw his new home. It was an apartment and they lived in the 2nd floor. From what Kenshin have seen, they have 2 bedroom, 1 kitchen, 1 toilet and 1 living room. It was not big but a nice house.

Like this a few months passed by ever since his birth. Kenshin was a kid so he have nothing to care about he can eat whenever he want with just a cry and sleep wherever he want. Kenshin would always cry whenever he was about to shit and almost never shat his pants or diapers.

Seeing this Kenshin's parents were happy as they knew their kid was definitely a genius as he can do such things. Kenshin was very happy recieving all the doting from his parents. His father was working in the police so he always comes home in the evening. So Kenshin was not afraid of his father dying during mission.

One day Kenshin was going outside with his mother. From him mother's arm he got to see the Hokage face carved in the mountain. Kenshin saw faces of 4 Hokage carved in it. He knew in which range of timeline he is in and just needed few more information to get the idea. As his parents don't discuss village affairs, he is clueless about the things.

Like this Kenshin was now 6 months old and he began talking basic things like mother and father. Hearing him say for the first time his parents became very happy, his mother cried tears of happiness.

And another 1 months later, Kenshin began to walk. This confirmed that Kenshin is a genius. His parents often brag about him being a genius so Kenshin became very popular in his neighbourhood. And many local aunty will come to pinch his cheeks and nose.

Kenshin attributed all these to the breathing technique as it strengthened his body and developed is faster than children of his age. Kenshin was now able to do the basic breathing technique for about 10 minutes continuously before he stops.

He additionally found that he is a sensory type ninja as he can sense his parents by chakra. Also he noticed that his chakra reserves have improved a lot in these few months. His chakra can be compared to his mother who was a civilian.

When he tried to sense how much chakra his father has, he was shocked as it was 100 times more than his mother even though his father is only a high level chunin. From this it can be inferred that Jonin and Kage have massive chakra reserves. But Kenshin knew if he progressed like this, he will definitely surpass them by a long shot.
