The highlight of Boruto: Two Blue Vortex Chapter 28 comes when Boruto receives his newly enhanced sword.
After requesting adjustments from Sumire, she not only repaired the weapon but redesigned it to maintain a chakra-cloaked Hagoromo mode automatically.
All Boruto needs to do is hold the blade, and the sword channels the required chakra itself.

The weapon also includes a defensive limiter: anyone not registered to the sword will immediately lose enormous amounts of chakra upon contact.
Sumire added this function specifically to prevent it from falling into the wrong hands. The chapter then demonstrates Boruto’s progress — he eliminates a Manmushi clone instantly, proving how far he has come.

One of the bleakest moments comes when Kashin Koji reveals a possible alternate future where Himawari and Ada both die. The vision shows Eno holding a dying Himawari, while Ada’s body is fused into the Shinju tree.
This implies that if Ada falls, Damon must have already been defeated, reinforcing that the Shinju are capable of overpowering the strongest characters introduced so far.

Koji refuses to share further details, claiming that too much knowledge could trigger severe consequences.

The chapter closes by teasing Kawaki undergoing an upgrade through a mysterious experiment conducted by Amado.
While the specifics remain hidden, it’s clear that both Boruto and Kawaki are being molded for their inevitable showdown.
Boruto: Two Blue Vortex Chapter 28 is packed with momentum — power progression, long-term foreshadowing, and emotional stakes.
With Karma control restored, the Shinju threat rising, and alternate futures hinting at tragic outcomes, the narrative is accelerating toward its next major conflict where every decision could reshape the fate of the shinobi world.
