Guts in first pages brandless

I don't know if you guys have noticed : Guts has no brand before we learn about it in the second part of volume 1. It's too bad !
Well, we can't really blame Miura for that ^^
I guess he made it like it for us to discover the brand when Puck sees it.

At the end of Vol. 14, in the Berserk prototype, Guts has the brand on its chest, maybe Miura decided to move it on his neck after the beginning of the Vol. 1 and hadn't had time to add it in the previously made work.
