Quick answers
When does Raizo first appear?
Chapter 804, by name only. Ch. 804, p. 2
Raizo is a ninja from Wano and one of Kozuki Oden's Nine Red Scabbards. His scroll techniques help him protect his allies, most notably when he releases water stored from Zunesha to fight the fire inside Onigashima.12
How did Raizo store Zunesha's water in his scroll?
Raizo captured seawater in a scroll while Zunesha was bathing itself. In chapter 1046, he releases that stored supply inside Onigashima using his Scroll-Scroll Jutsu. The water comes from Zunesha's earlier bath; Raizo has kept it ready for an emergency.2
His preparation comes from the burning of Oden's castle twenty years earlier. Remembering how helpless he felt when Oden's family was in danger, Raizo resolved to be prepared if another fire threatened the people he was trying to protect. During the raid, he finally puts that preparation to use.2
What did Jinbe do with Raizo's water?
Raizo supplies the stored water, and Jinbe directs it. Jinbe uses Fish-Man Jujutsu to send the released water through the castle, carrying the flood toward the burning floors below. Their combined action turns a large reserve of water into a rescue effort across Onigashima.23
The sequence is explained in One Piece chapter 1046. Reading Raizo's release together with Jinbe's response makes the division of work clear: the scroll stores and releases the water, while Jinbe controls its movement.2
Zou and the Kozuki family
The minks keep Raizo hidden on Zou. His survival reveals the strength of their bond with the Kozuki family, whose retainers include Kin'emon and Kanjuro. When the Straw Hats finally meet him inside the whale tree, Raizo is being kept hidden near the Road Poneglyph.45
Raizo initially resists the crew's expectations of a storybook ninja, but then demonstrates smoke and clone techniques. The meeting connects the alliance's search for a missing companion with the Kozuki family's wider history.4
Udon and the Onigashima raid
In Udon, Raizo helps free Kawamatsu by bringing his key and sword during the prison uprising. This reunites another of Oden's retainers with the allies preparing to fight for Wano.6
During his confrontation with Fukurokuju, Raizo explains that the Scabbards' loyalty is rooted in their shared life with Oden. They continue fighting to fulfil his hopes and secure a future for Momonosuke. That personal commitment also underlies Raizo's determination to keep the raiding force from dying in the castle fire.12
