Ok, so; this is going to disappoint you, but I can't say that I'm all too familiar with either one. Is Anime the cartoony pictures of people with the big black sparkling eyes? Or is it a show? I've heard of it, but I've never really looked into it, partly because it is what seems popular (and I stay away from the popular things) and partly because my mom's friend is kind of obsessed with it, and I avoid things that I'm afraid of getting addicted to.
Isn't Manga, like, comic books or comics or something? I haven't actually heard of it until now, where I did a quick Internet search and saw something about that. (I was literally just trying to see if I was familiar with it, with a different name.) personally, I haven't been much interested in comic books for quite a few years now. When I was, oh, maybe six or seven, I liked looking at the Marvel and Fantastic Four (and maybe another; I don't remember), but I don't have much interest in them anymore. That may be because my dad, when he came along again, sort of didn't like me liking that stuff, but otherwise I don't have much of an opinion of it.
I know that didn't answer your question very well, but if you want a better one, I'm afraid that you're going to have to explain them to me. If you hate me now, don't be afraid to express that as a comment to this, either.
