Idk how it could happen or what kind of AU would lead to this but this is a v depressing concept, I approve lol. Idk what to add but I think I can safely say that Guts wouldn’t leave him in a cave for 2 years tho.
(relatedly, Casca as Godhand? I mean there’s no way to reverse their roles without changing literally everything about the story but still, Casca as a (scary, not naked and slan-y) demon god…)
Hmm Casca as a Godhand. The only thing I can think of that might make her become one is something like: she snapped and thought “I’ll follow my own dream/live for myself, because everyone I love uses and abandons me or puts their own dreams before me” but I honestly can’t see her making a sacrifice.
