I can imagine that this will be seen in a cutscene during Guts' first transformation. But would you really want to see this animation every time you go into beast mode during gameplay?
Nice thread!
This song called "Guardians Awaken" from The Legend of Zelda: Skyward Sword sounds very Berserk-ish to me.
It perfectly fits the Apostle fight scenes as well as the Eclipse.

kaimera has already shown the German version, but there was also a series of very limited boxed sets, called Berserk Collection 1-5.
Each of those boxes contains 5 volumes. Unfortunately they were discontinued after the fifth collection.
