The battle at the Valley of the End tore open the space-time continuum. Uchiha Sasuke and Uzumaki Naruto fell into a world of nothing but oceans, pirates, and Devil Fruits.
From the start, on Sky Island, Sasuke accidentally ate the Rumble-Rumble Fruit, fusing its power with his Sharingan. Enel, who called himself a god, was little more than a laughable “battery” in Sasuke's eyes.
Naruto, meanwhile, used a single “Multiple Shadow Clone Jutsu” to crash the “Mantra” that supposedly let its users foresee everything.
They had set out to find a way home, but ended up aboard the ship of Whitebeard, the World's Strongest Man.
“Gurararara... Be my sons!”
From then on, two twin stars appeared on the seas, sending even the World Government trembling.
Marine Headquarters? The Paramount War?
When Sasuke's Complete Body Susanoo stood proudly at the bow of the Moby Dick, gazing coldly down at the Three Admirals, he spoke Whitebeard's declaration for him:
“My family is mine to protect.”
Celestial Dragons? The Five Elders?
When Naruto unleashed his full Sage Mode and his Nine-Tails chakra resonated with the Mythical Zoan Fruit, he kicked Akainu into the ground. The whole world heard his roar:
“I don't care who you are! Touch my old man or my brothers, and I'll kick you into next week!”
Years later, when the divine throne atop the Red Line began to totter, people finally remembered the terror of being ruled by those twin stars.
And it had all started with two lost children finding a new “home.”
