Boruto Reveals Secret of Kawaki’s Past
Boruto: Two Blue Vortex is gradually building up to the next major arc against the Divine Trees, and the latest chapter finally explains why Boruto Uzumaki has kept Kawaki’s significant role reversal secret all this time. The series has been unfolding three years after the events of Boruto: Naruto Next Generations, which concluded with a massive cliffhanger where Kawaki forced Eida to use her Omniscience to make everyone in the Hidden Leaf Village believe he is Naruto’s actual son and Boruto killed the Hokage, causing Boruto to become a fugitive for years.
The manga’s first major arc has been revealing the significant changes in the Hidden Leaf Village in the three years since Boruto was forced out, with Kawaki becoming one of their most trusted allies. However, as Boruto heads back to the village to help with the Divine Tree threats, Kawaki begins to wonder why Boruto hasn’t tried to reveal the truth. But Boruto believes it wouldn’t make a difference anyway.
Why Boruto Is Still Keeping Kawaki’s Big Secret
Boruto: Two Blue Vortex Chapter 15 sees Boruto and Kawaki meeting up in the Hidden Leaf Village as they have their first real conversation since the time skip. Kawaki doesn’t immediately attack Boruto, allowing the two to actually talk it out for once. Kawaki wants to know why Boruto hasn’t told the others about his using Eida’s power, and Boruto truly believes that nothing good would come from telling the truth about what really happened.
Eida’s ability works in a much more complicated way than initially thought, rewriting everyone’s memories to make them believe Kawaki is Naruto’s real son and Boruto is the outsider. Boruto knows that telling everyone wouldn’t amount to much because even if some believe him, others won’t. It would cause unnecessary problems when the Divine Trees need the most focus to defeat before things get even worse. So in Boruto’s eyes, as long as the Hidden Leaf Village functions normally during this situation, he’ll be fine with being labeled a rogue ninja.

Telling the Truth Won’t Work Anyway
Omniscience is such a tricky ability that even if Boruto tells the others the truth, it won’t work anyway. Because even if he has supporters who believe him, Eida’s power is constantly rewriting their memories. It was previously showcased that Shikamaru was able to piece together that Boruto is likely Naruto’s real son, but even he himself could not trust his own memories. His head became cloudy when it comes to Boruto, and he even started to forget why he feels that Boruto is telling the truth.
Sarada Uchiha and Sumire Kakei are the only ones who have been able to completely avoid Eida’s power without having ties to the Otsutsuki that Boruto and Kawaki have. Everyone else would likely forget any support they have for Boruto, so unfortunately, he’s right to make this move. Telling the others would only complicate things further. With threats like the Divine Trees out there, the Hidden Leaf Village needs as much united power as they can muster.
