What animes do you remember had "If we were not enemies, we could have been friends..

[Star_Of_Hope]

I am sure you must have come across such characters in some anime.
If you remember any, do share them here. I can only think of Sasuke and Naruto at this point.
Well that changed later but that's another point.

there are too many characters like that
i am sure you them in anime. like ulquiorra and ichigo. they could have been friends if not for the shinnigami and arrancar part.
