Sayaka stood out to me with Azura. Sayaka would think of Azura's composure as stoic but understandable, but she'd want to try to take Azura on nice adventures.

..Also Sayaka would freak if she saw Azura walking in water. Lifeguard alert! Lady in the water singing!!!

Hana would be entranced by her singing, and would want to sing with her. Otherwise super interested in her powers to lull dragons.
