Thank you so much!
Yeah it’s really unfortunate that a large majority of the fandom is totally steeped in homophobia bc honestly the most compelling aspect of Berserk (imo but also lbr objectively) is Griffith and Guts’ extremely charged relationship, and I think the fact that so much of fandom tries hard to downplay it is kind of itself proof of how super gay it is lol. Like they can insist it’s just platonic but the fact that they feel compelled to ignore huge important plot points like eg the fact that Guts’ sole motivation for leaving the Hawks was to become Griffith’s friend, or the fact that Griffith textually valued Guts over his dream, etc, is pretty telling. Would they need to ignore so much if they really believed they were only platonic bros?
(lol sorry think I just had to get that out of my system and you gave me an opening.)
But anyway wrt your question, I think it would depend why Guts chose to stay (did Griffith win their second duel? did some action of Griffith’s convince him that despite the speech Griffith does value him ridiculously highly? or did Guts never hear the Promrose Hall speech in the first place?), but regardless of the exact reason Guts stays, I imagine that Berserk would end up being pretty much a really compelling story about medieval politics and relationship drama lol.
Like, take the tone of Tombstone of Flame Part 2, and that would be Berserk. Cool political scheming and complicated yet intense character relationships. Actually I say “relationships” but really it’s just Guts and Griffith’s that gets the real intensity and complexity lol.
Tho speaking of, I don’t really know where Miura could’ve taken their relationship in this alternate version of Berserk. Like, I can only see them eventually getting together if the Eclipse doesn’t happen ngl. But idk I guess this version of Berserk would be shorter, and maybe Guts and Griffith would have some conflict (eg if Guts lost the duel, maybe Guts’ feelings of inadequacy vs Griffith’s feelings of rejection) that eventually gets resolved. Ooh yk the logical happy ending for them in this kind of AU would be Griffith forced to choose between his dream and Guts and choosing Guts.
So yeah how about that? Political scheming, Griffith’s rise to the throne, both Guts and Griffith filled with self-loathing and their relationship totally tanked because Griffith thinks Guts wanted to leave and he forced him to stay, and Guts thinks he’ll never be someone worthy of respect in Griffith’s eyes, neither of them acknowledging this and Guts maybe continuing to help him but beneath the surface their closeness is gone, but then plot happens, Griffith demonstrates how he really feels once again but rly decisively this time by prioritizing Guts over his dream again, and they both start to figure their shit out.
As for a no Eclipse AU, I think it’s actually the perfect scenario to force Guts, Griffith, and Casca to actually deal with their issues. Like, in canon the Eclipse is basically a giant distraction. For Griffith it’s an escape, for Guts it’s an excuse to bury all of his emotions except rage and swing his sword at monsters for 3 years (and that’s his own escape and outlet: “when I’m swinging this sword… I don’t have to think about anything”), for Casca it drives her insane and puts her entire character on hold.
Without it what you have is Griffith with no dream, his emotional dependency on Guts mirrored by his physical dependency, and no escape from either his feelings for Guts or his feelings of failure and self-loathing. You have Guts who has just realized how hard he fucked up, who blames himself for ruining everyone’s lives but especially Griffith’s, and who has just figured out how much he actually means to Griffith. And you have Casca who… idk I think maybe her biggest issue now is with Guts and Griffith both losing/giving up their “dreams” and gravitating towards each other, she’s lost her motivation. She switched from supporting Griffith’s dream to supporting Guts’ dream and she has to let both go and support herself instead of dudes imho. And okay, maybe Miura wouldn’t go that direction with her character, but idc.
But I’m going to stay vague on how these issues could be resolved and lead to a low key happy ending because I’ve had this as a fic idea on the backburner for ages and someday I might actually finish it lol.
