I havent red the manga since last summer and recently i restarted to watch the anime. I dont really plan to restart reading the manga but after a quick look, i saw that 8tails was extracted from B and he survives now being connected to one of his tentacles. I did a bit of research on forums and some people say that before being sealed away, gyuki ripped off one oh his tentacles and thats the one B is using now, but, if i remember correctly, when kakashi used kamui on octopus, one of his tentacles was left behind. Is that tentacle the one used by B or did someone absorb that tail or is it just a significan amount of chackra left unused on the battlefield?
