We have some scans that enlighten us on story for The Last Naruto movie. The scans explain that Toneri Otsutsuki had plains to capture Hinata but instead captures the wrong Hyuuga sister and ends up with Hanabi instead. As to why Toneri is after Hinata isn’t explained but it seems their is something between the Hyuuga clan and Otsutsuki clan. Also the scans hint that feelings will crash across time. Once can take this as feeling between characters that might have been hidden may be revealed in this movie though how many is hard to say since their are so many characters. You can check out the scans below which include Sasuke and Sakura along with those who have been revealed in animated pics.
As always thank you for reading.
