Arc 6The Uchiha Concubine
Yayoi built ties with Konoha and Sunagakure while advancing his puppet program and investigating the origins of chakra. Izayai entered his household as the Uchiha Clan’s agent, and the arc ended with Hisana setting out to meet Kano in Oboro’s ninja gear.
- Yayoi exchanged the Land of Night’s Puppet Technique system with Sunagakure’s Wind Release system and arranged an exchange student program with Shamon.
- Yayoi traveled to Konoha with Kicho and Hisana, completed a trade agreement with Tobirama, and learned that Mito’s attempt to inspect Hisana’s seal had exposed the Land of Night’s secrecy concerns.
- Yayoi welcomed ten Sunagakure exchange students and demonstrated his puppets, then suspected Formless might be the legendary puppeteer Monzaemon and ordered Irori to monitor him.
- Yayoi visited the Tsuchigumo Clan, retrieved Komurasaki’s Chakra Crystal Core, and studied records about Hagoromo and Kaguya before deciding to pursue the source of chakra.
- Yayoi taught the exchange students that puppet masters needed Taijutsu and showed Izayoi the Inner Court, its Puppet Samurai, and the Seven-Tails before sparring with her.
- Izayoi admitted that the Uchiha Clan had sent her to approach Yayoi, and Yayoi pretended to view Hisana as a threat so Izayoi would help suppress her.
- Izayoi told Hokuto that Yayoi had chosen her as his concubine, while Hokuto warned the Uchiha Clan that Yayoi might be using them against the Uzumaki and Senju-linked forces.
- Yayoi thanked Kano for helping establish the Land of Night’s Medical Ninjutsu system, then asked Hisana to meet him and watched her leave wearing Oboro’s ninja gear.
