Chapter - Brothers from Opposite Worlds
[Naruto looks shocked after hearing this]
Hagoromo- Well my sons did have a good life after all, but..
Naruto- But, what?
Hagoromo- ...Indra's hatred for his brother did not start when I chose Ashura as my successor, but when he unlocked his Sharingan.
[Flashback shows Ashura and Indra sitting outside, watching the mountains]
Ashura- You know big brother, I really hope this war ends!
Indra- You'll have to become as strong as father if you wanna end it.
Ashura- Big brother maybe you can teach me how to awaken your Sharingan!
Indra- My Sharingan? Hmph you lack the talent.
Ashura- [Sulks comically] Yeah... you're right.
Indra- Hey don't cry! Grandmother Kaguya said we need to be brave like Father and Uncle!
Hagoromo- Years later Ashura's eyes naturally evolved into an Mangekyo Sharingan.
Naruto- Mangekyo Sharingan? That's the same eye Itachi and Sasuke have!
Hagoromo- Not necessarily...
Hagoromo- Indra's dojutsu was called the True Mangekyo Sharingan. A kaleidoscope which mirrored the hatred not of his heart, but the hatred of the Shinju's soul which he inherit.
Hagoromo- And I can say... your friend, no.. your brother Sasuke, is Indra's reincarnation.
Hagoromo- Anyway, that man named Madara will be defeated by Indra and Ashura, Sasuke and Naruto. I hope you both can stop the cycle of hatred.
[Naruto and Sasuke both wake up.]
