[Dr Kain]

Probably the same people who subbed Gokaiger. I would see no reason for them not to.

As for GUIS, I'm not sure I'm going to trust them again, as it seemed they just dropped Gokaiger at episode 28, so I went with Nihon afterwards, which was very annoying. I hate switching fansub groups in the middle of a series, as it throws everything off. Anyway, Nihon is who I am going to stick with. They might take longer, but at least they release the entire series and the files work on my BD player.
