I don't really know how fuu died and I thought it was because of bijuu extraction, but one of photos' descriptions on side says: "Torune being reincarnated with Fū as the sacrifice." If she died because of sacrifice, how the bijuu was extracted? And if it wasn't at first, shouldn't Torune become jinchuuriki? Or Bijuu was extracted later from Torune?
