Ōtsutsuki

Kaguya Ōtsutsuki, the Rabbit Goddess, mother of Hagoromo Ōtsutsuki, the sage of six paths and Hamura Ōtsutsuki.

What if Kaguya had a third son?

What if that third son was full Ōtsutsuki, unlike his half-brothers?

What if that third son was a carbon copy of Kaguya Ōtsutsuki, but the male version?

What if that third son sided with his mother instead of his half-brothers?

Ryuunosuke Ōtsutsuki the Dragon God.
