He is a blade Tobirama Senju planted in the heart of the Uchiha Clan.
He has spent more than a decade undercover in the Konoha Military Police Force.
On the night of the Uchiha rebellion, the blade leaves its sheath.
On the night of the Uchiha Clan Massacre, Uchiha Izumi tries to kill him to awaken her Mangekyo Sharingan.
Only when he is driven to the brink does he realize that he has never truly seen this man for who he is.
The seal on his Senju bloodline is broken, the Yang Seal is reversed, and Kirima regains his youth.
Right in front of Izumi, he speaks his first honest words:
"My surname is Senju. My name is Senju Kirima."
From then on, he alone stirs up Konoha's undercurrents.
He buys Tobirama's old home, reclaims the Senju Sage Arts, earns bounty money, saves up, wages a secret struggle against Danzo, and sets things right.
"I have no interest in becoming Hokage. I only want to restore the glory of the Senju Clan."
