Naruto and Sasuke jump high into the sky, manifesting their Kurama cloak and Complete Body — Susanoo, respectively. Sakura completely releases her Strength of a Hundred Seal, and jumps even higher into the sky, gathering a massive amount of chakra in her fist. The three connect their attacks on the opponent, Sakura from above, Naruto and Sasuke from the sides.
This technique appears to be inspired by Team 7's last attack on Kaguya. Additionally, Naruto and Sasuke's attacks resemble the collision during their final battle, which first appeared in a two-page spread from chapter #695.
