In the waters not far from Wano Country, the Whitebeard Pirates, led by Ace, were engaged in a fierce battle with the Big Mom Pirates. Although they were not fighting to the death, the clash between the Emperors of the Sea felt like the end of the world. Their terrifying and majestic Conqueror's Haki collided, enveloping both in black and red lightning. An immensely heavy pressure formed a domain of its own, and the sheer force of their Haki tore the sky apart.
Clouds rolled backward, and huge waves churned endlessly across the surface of the sea. Amid the violent shockwaves, more than a dozen surrounding ships rocked unsteadily. This sight left the members of the Big Mom Pirates pale with shock, because here was another guy connected to the Straw Hat Boy, and he was just as terrifying—holding his own even against the monster-like Big Mom.
