Arc 6The Lookout and the Secret Realm
Itō Yuying trained young ninjas, searched for the Dragon Ball materials, and built Korin Tower as a place to prepare children for an approaching threat. After Nii Raiu was abducted and found living with Madara Uchiha, the story left the veterans struggling through the Secret Realm’s dangers.
- Itō Yuying trained students in Kumogakure and Kirigakure, then returned to Konoha with Hana, Yumengliang, and Qingliu, who soon demonstrated their strength on missions and in sparring.
- Nii Raiu unleashed an Energy Wave during training, but Black Zetsu abducted him and brought him to Madara Uchiha, who tried to recruit him and let him stay nearby.
- Itō Yuying told Tobirama Senju about the dangers of overusing the original stones and his plan to create Dragon Balls, then left Konoha to build Kami’s Lookout.
- Itō Yuying built Korin Tower in the Land of Hot Water, introduced Korin as its guardian, and explained that children under ten would train there in Ki to prepare for an unknown outside threat.
- At Yugito Nii’s request, Itō Yuying located Nii Raiu in the Land of Rain and told her he was training with Madara Uchiha, so she chose to leave him there for now.
- Tobirama Senju and Itō Yuying brought the Kage and their companions into the Secret Realm, where its pressure overwhelmed newcomers and Zuǒhé transformed until Tobirama sealed his chakra.
- The veterans ventured toward the Endless Sea of Blood and fought swarms and beasts, while the Raikage stayed back with Killer B and the future Third Mizukage revealed threads that tore through nearby beasts.
