Agreed on it being the best op of the season. Here's the full song for anyone interested. I enjoy the show well enough. It's certainly my kind of ecchi trash. If you really appreciate thighs it's worth checking out. I have heard that the manga gets better.
Yeah, I wish the last scantalation group was continuing the translations, but I understand why they aren't. K-manga introduced a sucky situation where a lot of fan groups stopped either because they were afraid of dmca take downs, or thinking they don't have translate anymore, since it's already being officially translated. Hopefully Grand Blue doesn't get censored, but we'll have to wait and see.
Still need to watch the movie, but I thought season 3 was really good. It probably had some of my favorite episodes from that season. The rap episode was probably my favorite. The dub was also super amazing, and I'll probably re-watch season 3 just for that, at some point.
Aww man, I'm excited for this one! We can always do with more straight fantasy anime.
