Oh - wow. As I said above, it's my own opinion. Anime has the origin in Japan, it's natural to listen them in Japanese language. But as I said, it's my own opinion. You said that if you know or speak English, it would be more natural. That's might be true, because you could hear instead read. Even I could do both, I will still prefer subbed. The reason is simple, the Japanese voice actress/actors put the feelings and so on. Which I don't see in dubbed often."I prefer to watch it in sub because that's how it was intended, and it's more natural."
This is the type of response I have gotten before.
