Did kaguya have it even before she ate the fruit?...
We cant tell for sure. I would say yes though.
Byakugan has to come from somewhere. The Juubi doesnt seem to show any hints of having Byakugan so far.
With having nature energy, it wouldnt really need it either. I bet Kaguya was born with Byakugan.
Seems like yes,But first where the hell did Kaguya came from?Will that remain shrouded in mystery like many till now
In the Japanese Myth ''The tale of the bamboo cutter'', Kaguya is a princess from the Moon.
Otsutsuki even means big bamboo tree. She wears a Hagoromo (feather mantle).
One of her names is the Rabit goddess. Her horns look like Rabbit ears.
The moon rabbit is a rabbit that lives on the moon.
I would say she is possibly not from earth.
