I am curious did they have any kids? If not how were there many sharingan user? Before Kaguya I doubt there was any Sharingan users?
If Indra didn't have have kids how are there many sharingan users?
If Indra and Ashura had kid how come there are no Otsutsuki? Indra and Ashura are both Otsutsuki, there are no sharingan user except for Uchiha.
