OP's salty I see.
Toneri's probably doing stuff to Hinata to bring out Haruma's power. Any logical person knows that since he's trying to create another Kaguya, there has to be a reason why he choose Hinata. Aka, she has potential. It's obvious that Hinata does something to Naruto to help him fight. Considering Toneri has Naruto's Rikkudo SM while Naruto's reduced to BSM, there's no way he can overpower him unless someone else contributes in power, such as Hinata with Haruma power. Basically OP, you're saying Naruto's Kurama link mode, is going to beat rikkudo SM, the power the databook says it's inferior to, without any outside help. Wow. You take buthurt to the extreme.
You solidified yourself as a salty hater with the statement "she will never surpass PT 1 Neji" lol!
