what power aside from what he inherited from his mother did Hamura obtain in order awaken the Tenseigan, because as we know Hagoromo's rinnegan is a watered down version of kaguya's Rinnesharingan, but Hamura's Tenseigan on the other hand is a stronger version of his mothers byakugan.

so my question is where did hamura get the Tenseigan from when he obviously did not inherit it from his mother. what are your theories?
