Well let's say after neji's death, toneri came to earth, took Neji thinking he is from the main family, ressurected him and fed him otsutsuki chakra, after that toneri learns that neji is not from the main family but from the branch family, so he decided to tell Neji bout the tenseigan and his plans, after toneri kidnaps hanabi, neji kills him and gained the tenseigan, so how OP will neji be with his skill + the power of tenseigan, we all know he'd be way stronger than toneri who did'nt have any battle experience unlike neji, how strong will his kaiten be and what not? Will he demolish KCSM naruto?
