Assuming this thread doesn't get closed because despite the assortment of flairs for discussing leaks, the mods seem to delete anything outside of the main thread, even though that's a mess where you can't find anything...
I went through the leaks and translated every single bit of dialogue about Rasengan: Uzuhiko, for those who want to see it clearly and all in one place:
[Code trying to figure it out]
Code: (What the...? These movements... This is beyond just dodging... It's not a genjutsu nor a doppelganger... This is...)
Boruto: "Rasengan... Uzuhiko."
[Eida and Daemon discussing it]
Eida: "Eh... It's a less flashy technique than I imagined... I wonder what makes it different from a normal Rasengan..."
Daemon: "Heh... Is this that Boruto guy? I can feel the ground rumbling ..."
Daemon: "No, that's not it. More than the ground... the planet?"
Daemon: "That guy... It's an attack that uses the planet's rotation."
Eida: "The planet's... rotation...?"
Daemon: "Yeah, that's it... Interesting."
[Boruto explaining it]
Boruto: "Wow... Didn't think you'd still be standing after eating a direct hit."
Code: (What...!? This... This rotation is...!!!)
Code: "Urk... What the hell did you do...!?"
Boruto: "You better savor it... Consider this a taste of your own medicine, from the very planet you were trying to destroy."
Code: "The planet...?"
Boruto: "The planet's chakra... A Rasengan infused with its rotation... That is Uzuhiko. Now... that power coursing through your body will never disappear, just like how a planet's rotation never ends."
Code: "... Rotation..."
Boruto: "The damage isn't completely permanent, but... your life will be over long before this planet's rotation stops."
Code: "Clever trick..."
Boruto: "However... it would be a different story if I release Uzuhiko. As it stands, you can either stay silent and wait for death, or hand over Ten Tails and survive. You're an idiot, so think it over carefully before you decide."
Code escapes shortly after that.
