Arc 2From Yakumo to Anbu
Ueno Kei survived the Kurama Clan crisis, learned that Kurama Yakumo had wanted him to live, and accepted Sarutobi Hiruzen as his teacher. He joined the Anbu, trained with the Scroll of Sealing, and began his first mission, where concern for his comrades shaped his ruthless choices.
- Kurama Yakumo trapped Ueno Kei and Yuhi Kurenai among monsters, and Kei killed her before Ido emerged and nearly killed them both.
- After the space collapsed, Kei encountered Yakumo in an unfamiliar place and, at her request, used the Lingyu Blade to end her suffering.
- Kei recovered in Konoha Hospital, then told the Third Hokage how fear and misunderstandings had driven the Kurama Clan conflict.
- Sarutobi Hiruzen rejected Shimura Danzō’s demand to exterminate the Kurama Clan, while Kurama Yeqiong led the clan back to its former base.
- Kei accepted Sarutobi’s offer to become his student, graduated early, and joined Akamatsu’s Anbu squad under the codename Hawk.
- Sarutobi identified Kei’s Lightning and Fire chakra natures, gave him the Scroll of Sealing, and advised him to gain field experience before his first mission.
- Akamatsu sent the squad to destroy a bandit stronghold near the Land of Fire and Land of Water border and retrieve classified documents.
- During the mission, Kei caught up with Fox, who confirmed they had obtained the target item and eliminated Ye Yi, while Kei’s concern for his teammates led him to kill suspected enemies without hesitation.
