Probably reading into things too much but koshirou’s face is looking shady as usual. Dude looks like he’s up to something every time he appears on panel…
He really looks mad sus when Zoro asks for Wado.
My take:
Kozaburo was let's say a decent swordsman but a better swordsmith. I'm saying this without checking Koshiburo's age so correct me on that one in any case but maybe he wanted Koshiburo to be a chad swordsman but he turned out to be some yet another "decen" or even "subpar" swordsman that wouldn't be able to even pick up Enma from the ground.
He put his next hope in Koshiburo's kid but it turned out to be female ( I assume here both Kozaburo and Koshiburo are mad chauvinists, tho Kozhiburo is probably reason why Kuina started this talk about female body and shit ). That would lead to Koshiburo experiencing love/hate for his kid seein her being so good but having behind his head that she is a female and he don't want her to suffer the brutality of being born with female body. Ngl stairs falling shit was too dumb to me always. I think it was just Ittoryu Koshiburo. That's why he that mad sus whenever Zoro said something Kuina related after her death.
