Stop Teaching! The Straw Hat Crew Has the Strongest Four Emperors Now!

Ronan transmigrated into the world of One Piece and gained an incredible ability to teach anything! His teaching of Haki, martial arts, swordsmanship, sniping, science, Devil Fruit development, and more was all god-tier! Every time he trained a junior who went on to become a powerhouse, or even one of the Four Emperors, Ronan's strength increased dramatically!

And so... the world of One Piece changed.

At Sabaody Archipelago, Kizaru said, "Moshi moshi! Requesting backup! This year's Supernovas are terrifying!"

During the Summit War, the Straw Hat crew joined the battle, astonishing both the Whitebeard Pirates and the Navy with their strength!

Akainu: "So what if Ronan is your teacher? I'll wipe you all ou-"

Suddenly, Luffy's hair turned white and blazed like flames. He awakened as the Sun God and exploded into action at Marineford! Akainu panicked!

On Onigashima, even Master Kaido had to call Ronan "Grandmaster" when he saw him!

When Law and Kid arrived at Whole Cake Island, Big Mom panicked upon learning they were Ronan's disciples! Her throne was in danger!

Whether they were the Four Emperors or the Navy, everyone panicked!

"Ronan, stop teaching! The Straw Hats are the strongest Four Emperors now!"
