Was this the Rinnegan Chakra Mode?
After the power of the nine Tailed Beasts completed its first fusion, a Six-Tomoe Rinnegan opened on Naruto's forehead. The moment it appeared, his speed and strength surged dramatically.
However, what truly delighted Naruto was the ocular technique that came with this Rinnegan.
Yomotsu Hirasaka!
It was the ultimate space-time ninjutsu. By relying on one's own Kekkei Mōra, the caster could tear open a black portal from thin air and travel back and forth between different dimensions.
In the entire Ninja World, only Kaguya Ōtsutsuki and Urashiki Ōtsutsuki could truly use this technique.
Naruto had never expected that the Tomoe Rinnegan he awakened would come with this ability.
Moreover, he quickly noticed that the Six-Tomoe Rinnegan on his forehead was extremely similar to Urashiki Ōtsutsuki's eye. With this eye, he could even make ordinary Yomotsu Hirasaka activate faster.
Other than the Rinnegan and his suddenly increased speed and strength, Naruto's appearance had not changed like Obito's or Madara Uchiha's. He had not grown horns, his skin had not turned white, and his body remained as it had always been.
After thinking it over, Naruto figured that it was probably because he had not entered the Six Paths level by becoming the Ten-Tails Jinchuriki. That was why he had not developed the mutated traits of the Ōtsutsuki Clan.
Now that he had activated Rinnegan Chakra Mode, he instead resembled Sasuke after receiving a cheat from the Sage of Six Paths.
At that thought, Naruto suddenly found himself with a rather unpleasant point of comparison.
When he deliberately stopped fusing the Tailed Beast chakra, the Six-Tomoe Rinnegan on his forehead immediately vanished, and his enhanced physical abilities returned to normal as well.
Unlike directly becoming the Ten-Tails Jinchuriki, Naruto had to slowly knead the chakra of
