@Georgio722 1. How would you even know that? We've never seen what the Uzumaki Clan members wear in their village.

2. It's only manifested in two known Uzumaki Clan members, the other several characters who are Uzumaki do not have them or they're not known to have them.

3. That is 100% true, Madara and Izuna were stated to be the first members of the clan to awaken the Mangekyo Sharingan and they were it's only wielders at the time. This is a Manga fact.
