Ten Tailed Fox wrote: Reread windstar. Marara said that the third eye could only appear in those who have the Rinnegan based on what Black Zetsu wrote on the tablet. Kaguya was no special case, as how else would Zetsu, Kaguya's will, know that. Kaguya is a special case because she was the only one to eat the chakra fruit and got unrivalled power. It was her third eye. She never had the dual Rinnegan that Hagoromo had (that's where her Byakugan were). To awaken her third eye, one need the power of the "Samsara," which is the Hagoromo's Rinnegan and get close to the moon, which required being the TT jinchuuriki as well, not just merely awakening Hagoromo's Rinnegan. Plus, Hagoromo got his power from her. She had a Sharingan-powered Rinnegan. She started with the Sharingan and the Rinnegan, reflected in her third eye. What BZ wrote on the monument doesn't automatically mean that she started with the Sharingan, @Foxie. Those rules on the monument apply to a regular person, but not Kaguya, who ate the fruit and was the first to awaken her third eye (which is also a Rinnegan). That's why she's a "special case."
