When will they post new episode in English.

If you are talking about the dubbed version then they are still in the processing of dubbing but they keep coming out fairly quickly but for now just watch subbed or read the manga. If you are talking about subbed then I think they are still coming out. I don't generally watch subbed but i can only find 300 when I know there is mais than that. It's so frustrating but right now i'm just leitura the mangá to keep myself busy.
