ok gonna be real I’ve never understood the “daigo is like a son to me” route that the writers took with kiryu. they’ve never, at least for most of their time knowing each other, felt like they’ve had a father and son dynamic– an older brother/younger brother one sure, or maybe a young uncle/nephew one. because I mean? they’ve known each other since they were both kids and they’re literally only 8 years apart in age. in y0 it’s implied that kiryu played with him and babysat him more or less when he was around 16-20 and it just doesn’t feel like a Dad sort of thing At All. kiryu was also a kid. just an older kid. daigo was a little brat to him just like an annoying little brother while secretly thinking of kiryu as a Cool Teenager he looked up to and wanted to be more like. it feels way more like an older/younger sibling sort of thing or something akin to that and it only starts being a little more like a father/son dynamic some time after daigo loses his father and feels the need to fill the void– which he couldn’t even begin to do until at least ten years later because kiryu was in prison. and it’s not particularly in a healthy way either, considering. well. like I said. kiryu’s never actually been like a father to him. I don’t even mean that in a negative way in this case, it’s just literally not the role kiryu fundamentally had in his life (especially because their age difference is a good 10-20 years too close to be that of a parental relationship.) so idk. having kiryu say all of a sudden that he sees daigo as a son (especially rather than as family in some other way) just feels kinda. wrong. and jarringly unfounded.

I mean shit, even majima would be more of a dad-ish figure to daigo realistically considering kiryu basically assigned him to look after daigo for like. years. while kiryu just kinda left without any known plans of reconnecting at all. or even kashiwagi on a certain level because of how he stepped in alongside yayoi after sohei’s death. kiryu has barely been around, hasn’t really showed any interest in legitimately being in his life, and has barely had any deeply personal interactions with him since they were basically both kids. and as much as I think how long they’ve known each other and what they’ve both been through is a means for a familial bond of SOME kind, there just seems like no room or evidence for a paternal role being taken on.

at least nothing healthy in that regard; if kiryu’s like a dad to him then he’s undoubtedly a deadbeat one and perhaps feels like a dad to daigo in a way because daigo’s paternal model (his birth father) was also emotionally (and probably largely physically) absent and near-impossible to live up to. that’d at least make sense, regardless of how unhealthy it’d be, but it STILL really doesn’t explain kiryu saying he thinks of daigo like a son.

it’s just. it’s such a weird thing to have him say and I wish it was this confusing because of nuance but honestly I just think the writers watered their dynamic down to supposedly father/son because it seems more emotionally impactful for kiryu to say “you’re like a son to me” than anything else he could’ve potentially said about their bond.
