Prior to meeting Kaneki in V14 I don't think they were anything to each other imo. It's not entirely clear what it means to have "rights" over a ghoul, but at it's most basic, it just means that they're that investigator's property. I don't know if it's still in effect because Kaneki has been "erased" and Sasaki is supposed to be treated as human, but at the time (and maybe still?), Kaneki became Arima's property and it was hinted at that he used those rights to create a Quinque from him.

Since Sasaki is one of Arima's proteges, he seems to be intrested in his potential. The CCG is trying to "create an investigator who can surpass Arima" and Sasaki is one of those people they hope can one day do just that.
