Development of Boruto 84 – Boruto Two Blue Vortex 4 makes many readers believe that the new enemies are the Ten-Tails who transform by absorbing chakra from others. There’s an anonymous guy who looks a lot like Sasuke. It is predicted that there will be a lot of support from readers who believe that the new enemies appear to be influenced by the strongest people they have absorbed. It is possible that the small trees have “borne fruit”, and their fruits are those new enemies.
Thus, during the time skip, Sasuke was attacked by the Ten-Tails. That time was probably not long after Boruto left the village. Only then did Boruto meet Kaji. Kaji cooperated with Boruto, instructing him in ninjutsu to turn him into a stronger ninja.
While Boruto has encountered the Ten-Tails and learned about the new enemy, Kawaki still has no information. What will the new enemies do next? Maybe they will attack Konoha, where there are many ninjas possessing powerful chakra. Kawaki will have to cooperate with everyone to protect the village. Boruto knows this and will return to the village again to support. That’s a bit of a guess, but there’s a high possibility that the next chapter will be full of text with a lot of new information provided.
