Summary
Roman Torchwick and Beacon Academy were both lost on the same day. Thus, when the headmaster of the former reincarnates into the mind of the partner in crime of the latter, they can agree on one thing: Cinder Fall must pay for what she’s done. But when Neopolitan and Ozpin find themselves disagreeing on virtually everything else, it’s inevitable that both start to butt heads over how to accomplish their shared goal.
To Neo, she’s got a parasitic brain friend who’s doing his best to tie both hands behind her back. To Ozpin, he’s got an amoral murderess for a host that he can only just barely restrain. And to both, it’s only a matter of time before their new ally starts to rub off on them…
