I personally haven't watched it. Do anime and other shows affect/delay your salat? Do they affect they way you believe in Allah S.W.T? Do you start believeing the way of Shaytan L.A is the right way? Do you start believing in magic and sorcery?
Listen, If all this affects you. Stop. This applies for everything. Watching movies,series playing games, reading books, going out with friends. This isn't only applied for anime or whatever.
If it doesn't affect you, go ahead.
When it comes to nudity just look it up if has some.
