Arc 2Leaving Konoha with Tsunade
Nobuhiko helped Kushina make progress with Kurama while surviving a Root ambush and gaining access to powerful techniques. After Dan Katō’s death left Tsunade grieving, Nobuhiko departed Konoha with her, while Kushina resolved to grow strong enough to join them.
- Kushina faced Kurama in the seal space, and he revealed his name before asking for time to think, and Tsunade praised Kushina’s first step toward him.
- Tsunade prepared to leave for the battlefield and entrusted Kushina to Nobuhiko, who began studying sealing jutsu with her.
- Danzo arranged an attack on Nobuhiko, but Nobuhiko killed the Root assailant and brought the evidence to the Third Hokage, who moved against Root and offered Nobuhiko a technique from the Scroll of Seals.
- Nobuhiko chose Fivefold Rashomon and encouraged Kushina to keep building her relationship with Kurama, and Kurama eventually agreed to let them experience his chakra.
- Kushina controlled a two-tailed chakra cloak and fought the Third Hokage, then, months later, she and Nobuhiko helped Tsunade cope with Dan Katō’s death.
- Tsunade gave Nobuhiko her grandfather’s necklace and decided to leave Konoha, and Nobuhiko chose to accompany her, and his Sharingan evolved as Kushina reacted sadly to their plans.
- Kushina gave Nobuhiko several sealing scrolls and promised to join their travels once she grew stronger, and Tsunade and Nobuhiko left Konoha together the next morning.
- In Ishikawa Town, Nobuhiko used a Shadow Clone to beat Tsunade at the casino, while Kushina asked Kurama when she would be able to withstand his power.
