Boruto used his ability "Infinite Shadow Clones of the Sage Six Paths: Ultimate Rasengan Barrage," creating thousands of clones that surrounded Kawaki and bombarded him with massive Rasengan attacks.
Kawaki retaliated with his ability "Eternal Flame Destruction: Ultimate Cataclysmic Inferno," summoning a massive explosion of flames that obliterated most of Boruto's clones.
Boruto then used his "Ultimate Chakra Armor of the Divine Dragon: Thunderstorm Dragon God Strike," bringing forth a massive dragon made of thunder and lightning that slammed into Kawaki with devastating force.
Kawaki countered with his "Omniscient Demonic Deity: Infinite Obliteration Judgment," a dark energy that destroyed Boruto's armor and inflicted severe damage on him.
Finally, Boruto unleashed his "Ultimate Jutsu of the Divine Tree Sage: Heavenly Blossom of the Divine Tree," summoning a giant tree that enveloped Kawaki and drained his chakra until he collapsed.
