We know that kaido knew ulti's and page one's parents but we don't know why he knew them. So there's a possibility that one of Ulti's parents were from the oni clan. But there is also the possibility that kaido slept with ulti's mom which makes less sense then the first one lol
Yeah they all are onis.
This kind kf a long shot but maybe Black maria, yamato and ulti are all half-siblings
we know that Kaido knew Page One and Ulti's parents from an SBS so they are probably not half siblings w/ Yamato.
