Yeah, MKR is definitely an anime. And they have been translated to english in case you'd want to know. They also have subtitled versions. In fact, i've been looking for the DVD box sets for like 2 years now. I finally found them a couple weeks ago, for 120 a set. At a retail location, no less. Nice.
Both seasons 1 AND 2. Now all I need is 240+tax.... lol.
And as far as I know, they released a second "remake" version of MKR also, same story, but different animation, and and the story was changed slightly to make it more "adult". I don't know too much about that though, so anyome please feel free to correct me wherever i'm wrong. In fact, i'd like more correct info myself.
