Boruto: Two Blue Vortex chapter #13 dropped multiple bombshells, including confirming several fan theories and even introducing a multiverse angle. After Boruto and Konoha's battle with the self-aware Divine Trees, it became clear that the young ninja had developed drastically in the past four years, and it couldn't merely be traditional training at play. Indeed, with the re-entry of Koji Kashin into Boruto: Two Blue Vortex, the reveal of his abilities, and the many possible futures at stake, the story will never be the same.

Koji Kashin had an understated presence in Boruto: Two Blue Vortex, but chapter #13 reveals that he has been involved since before the events of chapter #1. In a flashback, Koji conveys the dire consequences of the Divine Trees' actions if left unchecked and how he can assist in fighting back against them.

While there are still plenty of questions for Boruto: Two Blue Vortex readers, the possibilities of where each future chapter could go are legion, thanks to a multiverse of futures both at stake and in play.

Boruto: Two Blue Vortex Hints at a Multiverse With Koji's New Powers

A New Shinjutsu Reveals a Multitude of Possible Futures

Koji Kashin reveals that he also has Boruto.

But Koji's revelations to Boruto, who is on the run now, talk about the many dark futures already prevented, while worse ones could still happen in Boruto: Two Blue Vortex.

It is difficult to prove what I've seen. Especially the events that didn't occur.

What I want you to understand is that our future has continuously been walking a dangerous tightrope for several years now.

-Koji Kashin, Boruto: Two Blue Vortex chapter #13

To illustrate this point, Koji brings up potential destructive scenarios, like Kawaki killing Boruto and Sarada after making Naruto disappear or if Kawaki and Boruto had never swapped positions through Omnipotence. These scenarios are each described in detail and paint a losing picture for Konoha's shinobi, including planetary destruction. But Koji takes extra care to illustrate one particularly distressing future he wants to prevent for Boruto.

The Very Worst Future Is Yet to Come

A disheveled Boruto hears Koji out about the darkest future that could happen, where the Ten Tails breaks free of Code's control, effectively predicting the emergence of the self-aware Divine Trees, namely Jūra, who can kill Boruto. Koji takes extra care to communicate Jūra as a lethal Boruto villain, which proves accurate, as his entry quickly shows the sentient chakra tree as one of the deadliest threats in the Naruto canon.

Boruto's chances for survival are slim, but Koji quickly reveals how his Prescience can be an asset in training Boruto to his best possible state in Boruto: Two Blue Vortex. By looking at the potential futures, Koji can learn the techniques that the alternate Boruto will learn, and impart them on the present one.

I could impart to the present you...moves and jutsu future you has mastered. Wouldn't that accelerate learning and optimize training?

-Koji Kashin, Boruto: Two Blue Vortex chapter #13

This explains Boruto's exceptional growth in the time-skip, especially with techniques like the Rasengan Uzuhiko and his seemingly vast superiority to Code in combat. The idea of Koji Kashin wielding a multiverse of possible futures, alongside the strongest possible techniques Boruto could master without invoking a time paradox, is enticing and layers on tons of possibilities. Yet, there's one future Boruto doesn't wish to cause at all costs, paralleling Naruto and Sasuke's conflict in the original Naruto series.

Much Like His Father, There's One Line He Won't Cross

Identically to how Naruto never intended to kill Sasuke but merely to bring him back to Konoha as a community member and friend, Boruto sees no scenario in the multiverse where he'd allow Kawaki to die. He says this to a silent Koji, seemingly indicating that this possibility may be unavoidable, especially in light of the Boruto vs. Kawaki showdown teased from the start. Still, it speaks to Boruto's steadfast loyalty to a friend who has betrayed him and sought to subdue him. Despite this, Boruto remains resolute, showing renewed spirits in light of this new ally and mentor.

Whether it's stopping a Divine Tree plan or whatnot, I'll never agree to any option that involves killing Kawaki, understand? Cuz knocking sense into my idiot bro...and restoring the Uzumaki household...is my goal!

Boruto Uzumaki, Boruto: Two Blue Vortex chapter #13

Whether this remains true is anybody's guess, as Koji has seen seemingly all possible futures akin to how Doctor Strange planned the gambit in the Avengers: Infinity War climax. As the story moves past this first fight, with Boruto in Konoha's captivity, readers must wait and see if he's given the same courtesy.

The reveal of multiple possible futures opens an avenue of possibilities for branching out the series. However, with a tidal wave of bad futures or "battle royale between destinies" on the horizon, Boruto will have to figure out a way to win back his former allies, as the planet's future is at stake in Boruto: Two Blue Vortex.
