Why do you have childhood memories there?

SAO, Naruto, and dragon ball are definitely not for kids. I’ve got no idea that the other three are so I’m hoping they’re at least for kids.

If that’s the logic that’s being followed, then almost everything is sinful. Eg, watching movies, buying stock, flying in an airplane, driving a car, etc.

I don’t know why you would think it’s sinful. As a Christian I’m pretty sure that dancing like that is just fine.
