I Survived in Anbu to Become Super Kage

Yako took off his Anbu mask in front of Tsunade, revealing the face mask underneath.

This was, to some extent, a show of sincerity.

Yako said, "Princess Tsunade, I imagine you've already guessed that my identity is rather special.

Now that I hold more authority, I can control the intelligence flowing around me. With my safety less of a concern, I'm no longer walking on thin ice like I used to."

Yako began making things up:

"To tell you the truth, Princess Tsunade, my mother was from the Senju clan.

Her giving birth to me was kept deeply hidden. It involved my mother's resentment toward my father, so very few people know about it.

Clan Head Rinmoku—your father—found me and wanted me to join the Anbu to act as a hidden spy for the Senju clan.

He was the only one who knew about this."
