So I was wondering... supposedly, if you agree on this, Sasuke's new eye is even stronger than the normal rinnegan since the latter derives, hypothetically, from Kaguya's or better Juubi's eye, and based on the fact that the Sage has a normal rinnegan, how was it possble for him, to give Sasuke an improved version of his eyes, while he himself hadn't access in Kaguya's improved sharingan?
What is the relationship between Kaguya's eye and sage's rinnegan?
