Arc 3The Land of Snow Mission
Issui fought to protect Konoha, formed an alliance with the reincarnated Hashirama and Tobirama, and escorted Kazahana Koyuki to the Land of Snow. He helped Koyuki defeat Kazahana Dōtō and left her free to pursue the dreams her father had encouraged.
- Issui defeated Baki, helped defend Konoha from Orochimaru’s invasion, and sealed Hashirama Senju and Tobirama Senju after surviving Tobirama’s attacks.
- The Third Hokage died sealing Orochimaru’s hands, and Issui faced blame before Konoha’s leaders and others defended his actions.
- Issui helped secure Sunagakure’s surrender, mourned the Third Hokage, and later drove Itachi and Kisame away from Konoha without killing them.
- Issui completed Kirigakure’s mission by killing the Wind Tanuki, then collected blood from Itachi, Naruto, and Tsunade to create bodies for Hashirama Senju and Tobirama Senju.
- Hashirama Senju and Tobirama Senju awakened in their new bodies and agreed to help Issui prepare for the coming war, while Tsunade became the Fifth Hokage and concealed their identities.
- Assigned to escort Fujikaze Yukie to the Land of Snow, Issui discovered that she was Kazahana Koyuki and protected her from Kazahana Dōtō’s Snow Ninja.
- Issui helped Koyuki accept her identity as the Land of Snow’s princess and defeated Nadare Rōga, Flying Swallow Fubuki, Fuyukuma Mizore, and Kazahana Dōtō.
- The geothermal generator warmed the Land of Snow, and Issui comforted Koyuki as she wept with happiness over her father’s message.
