Absolutely Not!! IDK from where आप get this idea but both are very very different.
Demon slayer is the ऐनीमे that revolves around demon hunters & they use breathing techniques in their fighting stances to kill demons.
The factors that made this ऐनीमे very famous are the एनीमेशन which is on a अगला 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 ऐनीमे so I suggest that if आप have not watched it yet then please do. I'm sure you'll enjoy it!
