I was thinking how such a thing could be a plot device, for example was the history of otome based on the manga. I don't even remember when it all started a millenia perhaps. and for that I could only link the anime and their respective mangas to be connected though with different plot lines of course anyone knows that.
yeah I missed it too. I could only gasps when I hear Shizuru's kyoto-ben on this vid:
LOL missed it heaps! I dunno why it got a lot of impact with me. I think I haven't heard that accent on someone else's seiyuu.
