Short Summary
Jinbe and Neptune have a discussion at Ryugu Palace about cutting off their connections to Big Mom and Neptune has found the flag he would wish to use to defend his island in case he loses Big Mom's, the flag of the Straw Hat Pirates. The Minister of the Right comes and alerts Neptune that there is a bomb inside the tamatebako that will explode when the box is opened. Luffy returns to the palace and tells everyone that he gave all the treasure he collected from Caribou to Big Mom and that he would fight her. In consequence, everyone is shocked and Luffy, Zoro and Sanji get beaten up by Nami. Caribou wakes up and tries to find the treasure he stole. He sees that Pekoms has it and tries fighting him only to be defeated with one punch. In the New World, the pirates that just escaped from Hody's slave army are attacked by the Marines. On a Marine battleship, Smoker is interrogating some captured pirates who tell him that the one who saved them was Luffy.

Chapter Notes

 * Chimney, Gonbe, Tashigi and Smoker are shown for the first time since the timeskip.
 * Chimney has become the station captain of Shift Station.
 * It is revealed that the Tamatebako has been filled with bombs that will explode when it is opened.
 * All the treasure Luffy, Zoro, and Sanji acquired from Caribou has been given to Big Mom and the situation is explained to the rest of the Straw Hats and King Neptune.
 * Pekoms is a Zoan Devil Fruit user with the ability to transform into a turtle. He has a bounty of 330,000,000 and he is also able to use Busoshoku Haki as he is able to defeat Caribou with a single punch.
 * Smoker is revealed to have been promoted to Vice Admiral and Tashigi is now a Captain. They are now officers in charge of G-5.
 * Jinbe and the other members of the Sun Pirates are currently serving Big Mom, and have been since Big Mom started protecting Fishman Island. This is also part of the reason Jinbe rebuffed Luffy's offer to join the Straw Hats as he is unsure of how to cut ties with Big Mom.

Trivia

 * Tashigi's skill in deflecting a cannonball using her katana is similar to Mihawk's skill in easily deflecting enemy bullets in Chapter 50.
