New Onigashima Project

The New Onigashima Project is the name of a military project designed by Kaido, which involves transforming Wano Country into a lawless paradise for pirates in order to oppose the World Government.

Details
Kaido announced this project during the annual Fire Festival held at Onigashima as Kozuki Momonosuke was about to be executed. Kaido plans to move his base to the Flower Capital, transform Wano into a pirate nation, and have Yamato replace Kurozumi Orochi as shogun, having beheaded the latter for opposing the initiative. All citizens of Wano, including those of the capital, would be converted into slavery, in order to provide additional labor for further industrialization of the country. Orochi's subordinates were offered a chance to join the Beasts Pirates or risk being punished with death.

Afterwards, Kaido and Big Mom plan to also find the Ancient Weapons and the One Piece, kickstarting the "final war" against the World Government and its new power.
