final boss fight was great thematically, other things not so, especially when 4.0 showed yotsuyu as an irredeemable piece of shit fascist except tthat one cutscene.
now she becomes a child and loses her memories, then proceeds to get them back due to the machinations of that insufferable little fucktoy, finally becomes an interesting character then dies.
i hated how they showed her while killing her parents too, they deserved far worse tbh
the whole expansion would be better if yotsuyu was like this from the beginning
