people seem really hung up on the whole cloning idea when the only reason Kuro is said to be a clone of Nijuro is because Kuro’s name sounds like the japanese pronunciation of “clone”. there’s been no other mention of cloning in the series. Hanazawa-sensei could always have something up his sleeve, but i doubt it will relate to Kuro coming back, at least not anytime soon.
I wasn't even aware about the name pronunciation, thanks.
My main reason for thinking this way though is because we already had 2 instances of transferring minds to other bodies. One is the cat and second is the baby. And since this universe already established something like this beforehand, it's very probable it was planned so no one could say that author pulled it out of his ass, once Kuro for example would be back.
I don't really want him back like this, I just can't convince myself that it definitely won't be the case.
