Yeah some people thought Viz had it but it seems like there was a company made by the Japanese companies involved with the production of the series specifically to market it in the US and when that borabed they probably gave up which is why crunchyroll got the rights to stream it and how Sentai was able to get the other distribution rights. That's my theory anyway. Cause Viz doesn't just give up licenses... I can't think of many instances of them doing that. One Piece I guess because they were distributing the 4kiRAB dub on behalf of Toei.
