I've wanted Kin to die for awhile, cause his death would be impactful. But I'm not holding my breath on that.
It could really be so good and tragic if done right, it would be so heartbreaking and traumatic for Momonosuke too, serious character developing potential and maturing for him to become a man one day. Even prematurely given his life so far ofc. Well more fuel for him to develop I mean by far, he's already been through so much horror and brutality ofc. With his parents both being confirmed dead, that does make it more bitter too.
I'm still wondering where the hell Hiyori is and why she's not involved here especially with her younger brother in so much mortal danger forso long.
Kinemon dying though definitely would be a profound tragedy for Act 3 and even post timeskip, given we've known Kinemon since Punk Hazard and thus how long we've known him and his character arc. Given he has his wife to reunite with after 20 years, I could see Oda being sadistic and killing him off so Kinemon can't truly reunite with her and live his life with her again, this time in peace and prosperity post Kaido and Orochi's rule and Wano being saved.
It would be similar to how Toki had to deal with losing Oden too?
Sadly, given Oda's adversion to commiting to killing off characters, I doubt he will die too. I kinda wanted all the Scabbards to die so they could reunite with Oden together, but I think Ashura should die regardless and maybe Inu or Neko at least. More likely Inu imo. I'll be really surprised if Kiku dies instead of Izo but it's definitely possible.
After Oda killed off Ace and supposedly killed off Sabo, I'm not averse to the idea of younger characters dying anymore though. He also really surprised me with Yasuie's death and whilst it lasted Pound's "death" too. He seems to be commiting to Pedro being dead too but I'm still wary of it myself. Pekoms might even still be alive too.
