The Third Otsutsuki Brother

Mother's Will

Kaguya had saved a piece of the Charka Fruit to create a son a pure full blooded Ōtsutsuki, one that would understand her, one that wouldn't leave her, one that was immortal.

He had almost feminine like features and pale white eyes
(Imagine it without the horn imagine his hair is as long as Kaguya's it dragged on the ground but because he can fly it doesn't drag)

And one horn on each side of his head just like his mother he also had a third eye he mostly kept closed

Time Skip
Hagaromo and Hamura had just sealed Kaguya away in the moon by themselves after Kazuya had refused to help, Hagaromo had sealed Kazuya in a cave it took Kazuya a day to get out by the time he had gotten out he sped away as fast as he could looking everywhere for his mother's chakra but then that's when he found it he sensed a little amount of his mother's chakra it was a very little amount but it was enough, Kazuya rushed straight towards the chakra but when he got there he hadn't see his mother it was something that looked half white and half black

Kazuya/Why do you have mother's chakra

Black Zetsu/I am Kaguya's will I was born  when she was sealed

Kazuya/Well then that makes you my real brother unlike those filthy half-breads, we need to work on reviving mother right away but first mother would need a home to stay in something massive bigger than a castle, we would also need to rebuild the Ōtsusuki clan and make our mark on history.

Black Zetsu/ I will keep an eye on Hagaromo for now while you make home for mother to live in

(Imagine all of them put together)
