As we heard and know that watching TV for example Hindu movies, America movies etc is Haram(forbidden), Only watching animals, things and world is halal. So we ask; can we watch Anime series (similar to cartoon)?
Mostly Anime have uncovered girls, Music and lost of haram acts. As far as i know, there is no anime (or cartoons) in which female characters wears hijab and there is no Musical instruments being played). So as they have mostly Haram things, they should be avoided. But in case you can Always SKIP every haram part, then you can watch.
