Oky hear me out i know this maybe a filler but last episode kinda suggest that the rinnigan is only achievable with the sharingan.

 

[Angelic.]

Maybe

Maybe? There is no ifs, ands, or buts about it buddy. Filler is filler. period

 

[ItachiDaSoloKing]

The Rinnegan is only Achieved by obtaining Both Indra and Ashura's power to Awaken Hagoromo's Power(Rinnegan)

Manga > Filler

That's filler. But manga phux said sharingan can evolve into Rinnegan. So Sharingan+Hagoromo's chakra = Rinnegan.
Or Sharingan(Indra's transmigrate) + Ashura's chakra = Rinnegan.

Filler is filler

 

[Ansatsuken]

The Rinnegan is only Achieved by obtaining Both Indra and Ashura's power to Awaken Hagoromo's Power(Rinnegan)

Manga > Filler

Rinnegan is only Achieved by combining Indra and Ashura's chakra only applies to someone that try to have Rinnegan eyes and not the Original user of that eyes (Hagoromo)

That mean It can be possible for Hagoromo to have Sharingan first before Rinnegan later. I said 'possible' and not a proven fact.
