Thank you, DrakoDarko
I love that Olivier drawing, and those sketches & comments!
Since I got few minutes to spare, here are my quick translations of Arakawa-sensei's comments. They may have a typo or two since I didn't proof-read. (After you click on the below thumbnail to get the larger image, click again to get the full size view so that you can read the comments.)
Left page is near-final designs of the Briggs trio and Grand, Right page is the earlier designs. Link
Earlier design of Olivier looks somewhat like the mixture of Lust and Riza. xp I like the final design of Olivier. ^^
And, oh my, the name "Briggs" was created by typesetting mistake/misunderstanding
! I've never imagined that! XDDD
