I, Uchiha Itachi, Protect the Navy's Justice?

"You foolish little brother, no matter what you become, I'll always love you."

Those were the last words Uchiha Itachi spoke after defeating Kabuto Yakushi and releasing the Impure World Reincarnation.

He arrived in the world of One Piece and awakened the Spirit Summoning System.

Uchiha Izumi, I will create a world where you exist!!!

On September 21, 1520, in the Sea Circle Calendar, the biggest news in the world was that a mysterious assassin had wiped out the Straw Hat crew, who had recently become one of the Four Emperors, leaving only one survivor.

Akainu picked up the newspaper and burst out laughing.

"Who knew the Straw Hats were really a bunch of straw men? They fall apart at the slightest touch."

Kizaru clenched his fists, his eyes murderous.

Fujitora paid it no mind and leisurely sipped his tea.

Green Bull's request to go capture Luffy was rejected.

Shanks immediately set off for Wano Country.

Dragon and Sabo, overcome with grief and anger, led the Revolutionary Army to Wano Country.

After enduring too much sorrow, Garp decided to resign from the Navy and return to Windmill Village in the Kingdom of Goa, in the East Blue.
