These are the 2 who work the spa. One being cerulean and the other a sea dweller. 

The blue one in the purple kimono is Solann and the one with the cat fish face and blue kimono is Terano. Truth is Terano is actually a boy and when guys ask him out, thinking he is a she, he just kinda laughs and tells them and they go running. They're actually super close moirails who just enjoy working with each other in a calming environment and helping other calm down and relax. 

Out in the normal world when they aren't working, Terano is super chill and smokes a little on the side but he has a huge gap between smoking and working so they will never happen together and he would go to work high. He loves wearing baggy shirts and jackets but always wears tight pants, just cause he thinks his legs look good. He's just a guy you would wanna hang with and laugh with when he gets confused for a girl.

Solann has an active life and while she also likes to just chill out, she does enjoy seeing the world and life to it's fullest. She loves doing her hair up in different styles but her favourite thing to do is flying in a paramotor. She owns one and sometimes likes to do trips and she will go and get food before just sitting up in the sky and enjoying the view. 

And I've been sitting on this design for a while but I can't anymore! So! Solann's Dancestor! 

Rancia loves things rock and heavy metal buuut she has a small online presence away from that stuff where she makes mashups. Her videos of and accounts keep getting taken down but she doesn't care and she knows she has some dedicated fans who will keep finding her and listening to her music. That music also being electro pop, alternative and things along that line. Her known symbols are either a snowflake or a melting heart. 

She also has a small messed up thing she likes to do where she would write love letters and send them to any random troll and just feel bad for the poor sucker that gets them and she never gives a return address so it couldn't be turned back to her. 

She also loves to make dances up to the songs she splices together. So yeah, she's an interesting one XD
