World at War: From the Start, Connecting the Ninja World and the Age of Discovery

What would happen if different worlds from anime and manga connected and gradually merged into one?

The battles between ninjutsu and Devil Fruits, demons and Soul Reapers, angels and devils, and more are about to erupt.

It all starts when the ninja world connects with the world of the Great Voyage.

Kaido of the Beasts: "The Akatsuki's immortal duo? Are you really immortal?"

Red-Haired Shanks: "Madara, whose face do you think carries more weight, yours or mine?"

Whitebeard: "Gurararara! I hear there's a remarkable medical technique in the ninja world that can cure my old ailments?"

Sengoku: "All Marines, hear my orders! Launch a full-scale invasion of the Five Great Ninja Countries!"

Madara: "Hashirama, come conquer the myriad worlds with me and build an empire of our own!"

Aizen Sosuke: "Soul Reapers? Hollows?"

"Boring!"

"Follow me as we conquer the myriad worlds! No one can stand against us!"
