"Kaguya had more than one grandson. To be precise, she had three."
"Three?" Confusion showed on Mikoto's face.
After all, the Sage of Six Paths was the only one famous throughout the Shinobi World.
"That's right, three. One was Hamura Otsutsuki—no, Hagoromo Otsutsuki, the Sage of Six Paths. He inherited the Rinnegan."

"That's right. The Hyuga Clan descended from Hamura Otsutsuki's line—the descendants who remained on Earth."
After hearing Uchiha Yin's explanation, Mikoto had a general understanding of what had happened a thousand years ago.
