Its just you. Its very Ukano to be honest, not wierd at all.
i think its because we don't usually see it in manga but i think its cute and modern
I think the localization team probably are using it in place of a Japanese pet name that doesn't have a one to one natural translation. Because we aren't used to seeing it in manga it can seem a bit strange
Well yeah, that's true. Makes sense. ╮(￣▽￣)╭
I imagine the translators chose 'babe' as a way to show how ukanos way of referring to sachio feels to JP readers, in the raws before they get together ukano calls him 'sensei' and starts calling him simply 'sachio' after they get together (mind you sachio never stops calling ukano 'ukano-san' so theres a gap there(▰˘◡˘▰ )
Is it just me, or does that BABE thing feels kinda out of place? Idk, it looks weird (￣∇￣")
