Garen soared into the air and slammed a Rising Dragon punch into the Dragon Form's lower jaw.
Kaido's Dragon Form suddenly shuddered, and its head shot hundreds of meters upward with the force of the punch.
The force of the blow was as mighty as a great river or ocean. Even after crashing into Kaido's body, it did not diminish, piercing through his scales, flesh, and bones before bursting out through his back.
The remaining force then stirred up a storm behind Kaido that swept across the sky.
The storm drove away all moisture. The rainbow stretching across the heavens vanished without a trace, leaving only a vast jade-blue sky.

However, that did not stop Garen from creating the effect of a machine-gun barrage.
That punch had already made the muscles throughout Kaido's body convulse and his blood surge, temporarily leaving him stiff and unable to move.
Garen, already high in the air, seized the opportunity to finish charging. Like an eagle spreading its wings, he descended from above and drove a punch down onto Kaido's head.

Because Hero's Spear had such a pronounced windup, Garen's fists did not look like a rapid, dense, and razor-sharp
