I think we missed an opportunity to have more mental arguments, even if the main point was to demonstrate all those different personality fragments exist in Karin prime.
But having a million voices in her head would have been funny.
So now that all the Karins merged back into one, is she shizophrenic? I mean, would it look like that to people not knowing the story? Not that it really matters. All Karins have gotten a happy ending
I'm going against the grain but I don't like this ending and I hate the final arc overall. I regret being emotionally invested in a series once again...
