Arc 1The Serpent in Kongoukaku
Saint Dio acquired the Boa sisters, trained them, and used his growing power to intervene in a world overrun by Kabane. After helping Kongoukaku survive an engineered invasion, he left with Mumei to pursue the Kurozumi Clan’s Haki and Devil Fruits in Wano Country.
- Saint Dio left Mary Geoise with Stussy, defeated the Slaik Pirates near Sabaody, and bought Hancock, Sandersonia, and Marigold at auction.
- Saint Dio fought Rayleigh as Area 26 sank, while Stussy fought the Kuja captain and took the sisters away, and back in Mary Geoise, Saint Dio branded and began training them.
- Saint Dio and Stussy pushed the sisters through brutal training, and Hancock began serving Saint Dio before all three sisters ate Devil Fruits and followed him through a portal.
- In the Kabane-infested world, Sandersonia and Marigold fought attackers, and Saint Dio stopped the Kotetsujō and persuaded Ayame and its passengers to take him to Kongoukaku.
- Saint Dio cowed Kongoukaku’s samurai and residents, while Stussy spread rumors of his arrival and manipulated Munechika Shikishima into seeking his support.
- Mima Karyotori’s coordinated attack brought Kabane into Kongoukaku, where Sandersonia and Marigold fought the horde and an aggregate while Mima killed Munechika.
- Saint Dio dissolved the advancing Kabane with Jörmungandr’s green mist as Mumei lured Mima into a gunpowder warehouse, where an explosion destroyed the aggregate and ended the invasion.
- Ayame took charge of Kongoukaku, Saint Dio restored Mebiki and gave Ayame five Zoan Devil Fruits for a defense squad, then departed with Mumei for Wano Country.
