Absolutely Not!! IDK from where 당신 get this idea but both are very very different.
Demon slayer is the 아니메 that revolves around demon hunters & they use breathing techniques in their fighting stances to kill demons.
The factors that made this 아니메 very famous are the 애니메이션 which is on a 다음 level & the tragic story telling behind all the villains. Though, I personally felt the plot could have been better but anyways it is a watching worthy 아니메 so I suggest that if 당신 have not watched it yet then please do. I'm sure you'll enjoy it!
