Ooh this is an interesting question, ty!

I wouldn’t change either Guts or Griffith’s backstories tbh, I think they’re actually pretty well done, and important to their characters and narratives without being the be all end all. Well, I’d like to make Gennon less of an evil gay stereotype and Donovan less of a scary black man stereotype but yk, other than those details the existence of rape in their backstories isn’t something I’d change.

With Casca… tough call. Her story is all about gendered violence to the point where if you got rid of the rape attempts you’d have to come up with a whole new story for her. But it’s still a shallower and less well-rounded depiction of abuse than either guts or griffith’s backstories, bc it’s so emphatically gendered, like, rather than informing her personality or her choices it’s just framed as being a woman.

So actually I guess for Casca what I’d change is (actually pretty obviously lol) her motivations. She’s not in love with Griffith, she idealizes his dream because she knows he wants to dismantle those power structures that fuck her over and create a place where those w/ power can’t easily abuse their power over others. She hates Guts not because she’s jealous of him (tho she could still be jealous of his emotional closeness with Griffith, like she’d still admire Griffith here even if she’s not in love with him and I like that rival dynamic), but because she recognizes that he could end up destroying Griffith’s dream.

Also I think we can still cut out most of the rape threats she gets while still showing that she has something to fight against. Maybe keep Adon being a gross dick (in all fairness he kind of mirrors Gennon towards Griffith which kind of shows how they’re fighting for the same dream – ie a world where those kinds of dudes are shut down) but have Casca just fighting for her life rather than against rape attempts as she runs from the 100 man fight.

So nothing really changes much until Guts comes back from his vacation. And now Casca is genuinely, genuinely angry and hateful towards him, because he did exactly what she’s been afraid he was going to do – destroyed Griffith’s dream, and her hope for a better future.

Which means they don’t have sex lol, Casca was never into Guts, they began a friendship towards the end of the war but nothing more. And now that Guts has come back Casca is actively hostile to him, though after Guts lets her stab him she probably forgives him a bit bc it’s not like he intended to destroy absolutely everything, and he’s clearly fucked up about it.

Also no suicide attempt.

So their dynamic during the rescue mission is resentful allies, like a throwback to their first three years knowing each other.

Wyald still happens but no attempted rape w/ Casca obviously.

Now when it comes to the Eclipse, I want it to be all about Guts, and I want it to hit the audience over the head with parallels to his childhood. It’s the Eclipse, it doesn’t need to be subtle. Rather than looking wistful when Griffith sacrifices everyone, I want Guts to look betrayed, I want him to look just as sad and horrified as he did when he was 11 and Gambino told him he sold him to Donovan.

Agh I’d hate to lose the creepy silent monster vibe from Femto, but something like a cold, “you’re still alive?” would be v fitting w/ the “you should have died” parallels. Tho idk I’m torn on that.

And ok I said I want it to be all about Guts but I can’t just kill off Casca. But if she’s gonna live the Eclipse needs some serious personal meaning for her too. So maybe her reaction to being sacrificed, knowing it’s for the dream she’s dedicated her life to and in theory she should be willing to give her life for it, and trying to reconcile that with the horrificness of the situation and her desperate desire to survive anyway. So she survives long enough for Femto to show up, because she’s not the third best fighter in the Hawks for nothing, and then…

torture? Femto has monsters hold Guts down and tortures Casca in a way reminiscent of a kid pulling the wings off a fly. She loses an arm, Guts keeps his because he’s too busy being utterly terrified and possibly flashbacking to hack his own arm off in a rage.

Like, one thing about the Eclipse rape, is that if Miura had to have it as a way of emotionally affecting Guts, how the fuck did he manage to draw like two chapters of awful awful shit with Guts being held down by monsters that he’d just watched rape Casca, and completely fail to allude to Guts’ own rape trauma? How. Hooooow it’s mind boggling. It’s absurd.

But you don’t even need the graphic rape for that, like hell, Miura has absolutely adequately set up the correlation between giant monsters Guts is compelled to fight and his own childhood trauma imo to justify Guts having a very emotional traumatic reaction to just being held down and made helpless by monsters after being essentially given to them.

There’s Black Swordsman Guts in a nutshell, and this is exactly what was implied to have caused him to go full traumatized amoral asshole. Before g*tsca was a gleam in Miura’s eye all he had were those parallels to Guts’ childhood trauma – Guts being given away to monsters by someone he trusted – and that’s all he needed.

So anyway, because Casca lives, she has her own reaction to being casually tortured by Femto before being rescued, which is also a replay of her childhood trauma but without the agency of killing her attacker herself with a sword. So her reaction could very well be similar to Guts’ – a desire to kill monsters and get revenge. Maybe she’s lost her idealism wrt the dream, and she’s more cynical now – a better world is impossible, best you can do is survive this one.

She and Guts go their separate ways because they’re barely friends, let alone lovers, and remember 2 brands = big ghost problems.

After this the narrative splits 3 ways between NGriff, Guts, and Casca.

I’m reaching the limits of my creativity lol. So I’m just gonna suggest that Guts gets the behelit, Casca gets the armour and the rpg group, Casca gets the moving on arc and hooks up with Farnese while maybe finding a happy medium between changing the world and lashing out against the world, and Guts succumbs to his inner darkness and gets a highly emotional confrontation with Griffith. Since he has the behelit maybe he uses it upon realizing that Griffith’s heart is still beating for him, bc the emotional conflict is just too much, and sacrifices Griffith to become a Zodd-esque apostle wandering battlefields and fighting for no reason, basically returned to his pre-Griffith state.

It’s probably shorter than 355 chapters too lbr. I’d say NGriff creates Falconia right before the confrontation with Guts, so yk he achieves his dream b4 ironically getting sacrificed. Otherwise his story doesn’t change much. Maybe stronger suggestions that he’s not as unemotional as he looks, to build up to a guts confrontation better.

Like… I’m not a very creative or good writer lol but I feel this general outline could be written in a very good and satisfying way by someone with talent, like Miura.
