In Boruto: Two Blue Vortex chapter 27, Masashi Kishimoto and Mikio Ikemoto have confirmed a major upcoming death in the story. Kashin Koji reveals that Uzumaki Himawari will die in the future, possibly caused by Shinju. However, this event triggers a new power awakening in Yamanaka Inojin.
Kashin Koji foresaw this future through his prophetic abilities. The exact cause of Himawari’s death remains unclear, but it is definitely linked to Jura, one of the main Shinju antagonists.
After her tragic death, Yamanaka Inojin, who appears to have deep feelings for Himawari, develops a completely new ninjutsu to avenge her. While Himawari is destined to die if nothing changes, the main characters in the ongoing story are fighting to alter this future, meaning the entire timeline could shift and Himawari will ultimately survive.
Kashin Koji’s vision confirms Himawari’s death

This revelation may shock fans, but in Boruto: Two Blue Vortex chapter 27, Himawari Uzumaki is killed in one of the main story timelines, likely by Shinju, the current main villain group. This implies that Jura is responsible after targeting Konoha. Kashin Koji used his prophetic technique to see this future and also discovered ways to prevent this tragedy.
According to Kashin Koji, Himawari’s death deeply affects Yamanaka Inojin, leaving him devastated and inspiring him to create a powerful ninjutsu for revenge. Koji tells Inojin: “You invented this technique yourself to avenge Uzumaki Himawari.”
This new technique is an advanced form of the Yamanaka clan’s famous Mind Transfer Jutsu. Although the full details of how it works have yet to be revealed, fans are eager to see what powerful ability Inojin has developed to cope with and avenge his great loss.
It is important to note that Kashin Koji’s vision of Himawari’s death is a plausible outcome. After all, defeating Shinju is nearly impossible, Koji revealed there is only a one in a million chance to defeat Jura. This suggests that in most future scenarios, the death of shinobi is inevitable.
Inojin and Boruto fight to change the future and save Himawari

However, all these grim futures can be avoided by taking significantly different actions or launching preemptive strikes. That is exactly what Koji and Boruto’s team are doing now, supported by Inojin’s new technique. Koji urges Inojin: “You will need to master this new jutsu within two days.”
The burden of saving Himawari falls heavily on Inojin’s shoulders, and whenever she is in danger, he must be there to protect her, just as she once saved him when he nearly died.
Himawari will not die in the current timeline because everyone is actively fighting to change the future for the better. Of course, this does not mean death is impossible for other characters in Boruto.
Given Himawari’s importance as the heir to the unique bloodlines of both the Uzumaki and Hyuga clans, she is unlikely to be among those who fall.
