See here, direct Otsusuki descendants have been banned.

"Ōtsutsuki Blood Relatives: Direct blood relatives of the Ōtsutsuki are also forbidden, given that most of them should be dead. However, if they will be created for a story-related purpose primarily and this is explained in great detail and the community approves of this, they may be introduced into the Fanon Canon Rebirth project."
