Naruto: Double Bloodlines from the Start, Bound to Konoha Sign-In

After transmigrating into the body of a war orphan born to the Uchiha and Uzumaki clans, Rento thought he had landed in the worst possible starting situation.

Then the Konoha sign-in System activated, granting him max-level chakra and a Three-Tomoe Sharingan from the start!

While his peers were still practicing the Three Basic Techniques, he was already figuring out how to use the Flying Thunder God and the Eight Gates as casually as basic attacks.

Kurenai Yuhi kindly brought him rice balls, and Anko enthusiastically challenged him to spar. Life was sweet.

Until the System issued its ultimate mission: save Uchiha Itachi on the night of the clan massacre.

Rento gazed toward the Konoha High Command and fell into thought. Did this mission mean he had to tear down Danzo's hideout first?
