My previous comment was aimed at Nick, I didn't even see your comment CNBA as you typed it out half a second before mine.

As for the similarity between this arc and the one from Rave, I wouldn't know, I've not read Rave and haven't watched it since it was on Cartoon Network however many years ago, and I don't think it ever got passed Haru getting the green coloured sword here.
