Sorawo's early preference for the Otherside over the normal world made me felt like she could go the way of Satsuki, though that probably wouldn't happen now unless she lost Toriko for good. Given all the distortion of time and space that seems to be tied to the Otherside, it doesn't seem impossible that someone might get sent to the past, allowing a Sorawo warped by the Otherside to become "Satsuki." But that's total conjecture for now.
