The 7th DVD and Blu-ray of Code Geass R2 was released on the last February 20 and among its extras, it came with a booklet with a new interview with character designer Takahiro Kimura, CLAMP (Mokona) and producer Yoshitaka Kawaguchi.
The booklet also comes with a few more of CLAMP’s original character sketches for the anime (although I think most of them, if not all, were published in the MUTUALITY artbook).
I totally missed this news on CLAMP-NET.COM, actually I think they only half-announced it and that’s why I missed it.
Without further ado, you can download this booklet here.
Much thanks to Aurelia for providing the scans and letting me know about it! ♥
