I'd like to offer Glacio as a potential fling partner to Zisma.

He's a Story-Teller in the Elimisha'sombea colony, which means he often moves to the outskirts of the colony to consult with rogues and learn all manner of knowledge from their experiences to speak with to his pride. He has a hefty thirst for knowledge and thinks of all things as a learning experience, rather than relying on his feelings for certain things.

If you're looking for an official mate for her, I'd also like to offer my boy Nyota for her! He's a rogue, but I'm toying with the idea of putting him into the Elimisha'sombea colony because they have a scholar section which dedicated to astronomy, which is his passion. Well, more like borderline obsession since his waking hours are always spent watching the night sky, causing him to often forget to eat in between sleeping and stargazing.
I can definitely see Nyota becoming "star struck" upon seeing Zisma, given that she looks like she's been cut out from the stars. He would probably insist that she was a constellation fallen from the heavens and follow her around for a bit, perhaps longer if they hit it off. Whether they became official or not would affect whether he joined the colony.
At the same time, I also want to offer Nyota for a mate plot for your girl, Chaka. Given that Chaka was once a mother, I thought of the idea where she could come across Nyota, who was delirious with hunger and take pity on him. After she helped him out, he would want to repay her in the only way he knew how: by teaching her about the stars and acting as a traveling companion. As time went on he would find that it was no longer because he felt indebted to her but more because he liked being in her company so much that he stayed and we could take it from there.
I would like to point out that while I offer these as mate plots, they can also just act as regular RP ideas too.
