Hagoromo Otsutsuki showed no emotional reaction to Naruto's words. Instead, when he saw those strange vertical pupils, a trace of complexity appeared in his eyes.
The Uzumaki Clan was descended from Asura, and Asura was his son. Although nearly a thousand years had passed, it should have been possible for a descendant to suddenly undergo a genetic mutation, revert to an ancestor, and inherit the Sharingan.

"Dangerous? Then tell me exactly what is dangerous about it!"
At those words, Hagoromo Otsutsuki's expression finally turned somewhat
