Dont get me wrong, I would love nothing more than for Guts and the Skull Knight to kill the Godhand and the Idea of Evil, drive every evil supernatural being out of our reality, Casca to get her mind back, the Elf King to regrow Guts's eye and arm, Guts and Cascas child to be a real boy, and for Guts to spend the rest of his days happy and having three ways with Casca and Farnese. And of course for Puck to become the new king of Midland...
However I dont think it will go down quite like that
Im not completly given up on Guts having a happy ending though, I just know it will get darker before the dawn so to speak.
