Naruto: I am Uchiha Shirou

Amid wind and snow, Killer Bee's eyes turned white, his skin bulging with ferocious veins, and a massive amount of Tailed Beast chakra continuously surged out.

It was as if an invisible black hole was greedily devouring everything.

Forbidden Jutsu: Chimera Jutsu!

With a rhombus-shaped mark emerging in his palm, Shirou's expression turned grave as the Eight-Tails' chakra kept pouring into his body.

"As expected of the Eight-Tails, possessing such a huge chakra reserve. But unfortunately, I am no longer just an ordinary ninja."

With the Mangekyō swirling in Shirou's pupils, his body was now developing toward the level of an Ōtsutsuki.

Or, more accurately, he was becoming a new type of Ōtsutsuki.

Ōtsutsuki + the body of a local sage.

This new fusion body, though still very weak and essentially newborn, needed to devour the power of these Tailed Beasts.

The Demonic Statue of the Outer Path he had cultivated before had long since been completely absorbed, and now his body was fused with the Divine Tree.

Although it was just a low-tier version he'd cultivated, the first step had been taken.
