Is it Naruto who is after her or maybe Naruto's Sexy Jutsu form (Naruko) has her own personality. If so then maybe she wants to eat Hinata in order to strengthen herself to the point of permanently taking over Naruto's body.
Then again, it could be someone else. Maybe one of the girls is after some Hinata upgrades to their curves? Or one of the guys might just think she's a tasty treat waiting to be gobbled up.
So who is it that's after Hinata?
