Despite the different tones between Berserk and Claymore, I really hope they reveal that Clare and Raki (Lucky?) live in post revolutionary Midland, and that the insignias the Claymores bare are in honor of Guts, the first demon slasher to survive. I do realize this is very unlikely, unless the mangaka got together and planned this out some. On the other hand, the Claymore world could easily be two or three hundred years after the Berserk world, and the plots would still make sense individually and together.
I hope Lucky gets some Clare action soon. I know I'd hit that.
