Inside the castle.
A certain black metal door swung open with a crash.
"Clack, clack, clack, clack."
A crisp sound came from within.
A somewhat short and slender figure appeared beyond the metal door.
A delicate face, silver hair, slender willow-leaf eyebrows, and an extremely pale complexion, paired with a white robe. A distinct Tomoe pattern marked his neck. His eyes snapped open, but his eye sockets were pitch-black, with no eyeballs from birth. Yet the intense chakra fluctuations faintly emanating from him proved how fearsome he was. This figure was none other than the last descendant of Hamura Otsutsuki, who lived in seclusion on the moon, and the purest-blooded Otsutsuki descendant of any generation—Toneri Otsutsuki!
Although the timeline in this life was two whole years ahead of the original, Toneri, who should still have been asleep and waiting for his chance, had been awakened ahead of time by Naruto and Neji's arrival. Even though he had yet to take Hanabi's high-purity Byakugan and combine it with his own Otsutsuki chakra to evolve his own Tenseigan, in terms of individual strength, Toneri Otsutsuki already possessed terrifying power that surpassed the average Kage Level.
Most importantly, the Giant Tenseigan surrounding the castle, also located inside the artificial sun, was Toneri Otsutsuki's greatest asset. With this Tenseigan, Toneri could defeat or even kill 99.9 percent of intruders in the current Shinobi World. But without a doubt, that figure didn't include Naruto, who could already fully control the Nine-Tails Chakra and Sage Mode. Even Nagato in his complete form had a chance of defeating Toneri if he made it to the moon.
The reason was simple: his own Tenseigan and someone else's Tenseigan were two different things.
Besides, there was only one here.
In the original, Toneri had awakened a pair of Tenseigan
