I am still experimenting with this story I will go through it once again to correct grammar mistakes.

I will try at the same time you can't expect from me , to give the exact copy of demon slayer breathing styles. I will give him one but it will be bit power down. I can't post chapter for few days due to my exams. Thanks for the idea man.

The problem is he will be too over powered. I want my MC to grow strong naturally but slowly at the same time he grow stronger by fighting.

I luv this idea and I am incorporating this idea in my work
