I hope you won't show the leaf 12 in this. They're weak and their interference in every arc would get annoying. This is a fanfic about daichi and he is what we want to see.
I'm betting Daichi ends up saving her after Orochimaru injects her with that serum, but before he extracts her blood afterwards. And Kabuto ends up being the one who dies. Anyone else have any guesses?
