"Breath in deeply, and let the airflow through your lungs, breathe in ..., breathe out rinse, rinse and repeat, "Rengoku told me

"Neet why did I not know of this before"I spoke to no one in particular

"You never really get tired, you train a lot without running out of breath your breathing is always constant and you always learning new tricks the more day pass," said Rengoku while looking at me

"Heh not my fault I'm physically stronger than you, "I said looking at him

"I was not blaming you in the slightest, to say the least, I'm impressed with your ability to have such incredible stamina, "he said while walking away

"Wait where are you going if I may ask, "I said

"I'm not gonna stay still and let you get any stronger than me. I'm the big brother and it's my job to protect you not the other way around," he said while fully getting out of my viewing distance

I just looked at him as he disappears, and then I sat down and meditated for a bit, good news as long as I don't meditate for too long, 'HE' won't appear, so after meditating for like 30min I got up and did the exercises over and over again, until I could do it on command.' I wonder if there is a way to keep it on at all times that's to be great for me.'I thought

I went to look for my blade sheath, and I found it under my bed. I took it and started to swing. I stopped by midnight, I felt like I could go on forever but I was about time I go to bed. If I ever run out of stamina in a fight it is either I fight someone so much stronger than me that I take too much damage or get worn out pretty easily or two some messed up bs but hey the chances of that happening are pretty low plus I have chakra so hey that a plus for me. (A/N if only you knew,)

Time-skip to a week

After a week of waiting someone came to the house, he was here to give me and Rengoku our sword, but dad wasn't there, he left 2 days earlier for some mission.

Masked men knock on the door.

I open it "oh if you come in do you want some tea while you stay," I said to him

"No, I'm just here to give Atoru and you, their swords (A/N Rengoku is his family name )

"That's me and Rengoku is already inside so come in, "I said to him happy that I could finally get my own sword

He remove his sandal and enter the house, he sat down and said

"WHO getting their blade first"

"I'd go first if that ok with you, " I said looking at Rengoku

"No problem with me you can go," he said

I raised my hand to grab the sword by the hilt and raised it, it started to change color from silver color to a dark red sword with a dragon-like hilt(A/n I'm not good at describing stuff as any human could tell)

"Nice dark red blade like the last one that I was using, it's pretty neat it looks amazing it's now your turn, "I said excitedly to see what he got

"You got a nice sword now it's my turn," Kyojuro said as he slowly took the second sword, the red flame pattern appears along its blade as the blade turn red

"My job here is done it was a pleasure to meet your all, "the man said before he left

'I thought they were all crazy huh I must have not watched any clips of it online'I thought taking of a special sword maker

After that, We went out to see Senjuro training outside but failing miserably to swing a sword but when he saw us"I'm so embarrassed you two are strong enough to become demon slayers but I can't even swing a sword properly "he said looking down

"Don't be embarrassed be proud of yourself because you worked so hard "said Rengoku with a smile on his face

"Thanks, you, " Senjuro said smiling and in tears

"You're the man of the house, while we are gone do your best okay," Rengoku said smiling

"Ok no one will get in without my permission, "he said smiling

"It's time for my first mission sees you and Atoru later," he said while walking off

"I'm gonna work hard to be just like you"

Senjuro said smiling

Rengoku stopped for a bit he smiled and left(A/N Goodbye Rengoku, I will see you when Atoru is 15)

'did he get some flashback or something, is that why he stops' I thought to myself

"Now let me help you with that cramped hand, let me heal it for you," I said as my hand glow a very soft green

"See your bruises are gone," I said smiling

"Thank you with this I can continue to train my hardest," said Senjuro

A crow flew by and yelled out "Atoru must go to the Miwauchi village ."

"Guess destiny call me to see you later little brother," I said

"Bye Atoru," he said

I smiled and left

(A/N you will not see him again)
