from episode of tooya:

Jinguuji Mai
She is actually the granddaughter of Jinguuji Tatsuzo (the man who found and raised Tooya). A tomboy and not very pretty, but for some reason, men find her irresistible. She does have one male friend, Morisaki Masato, who is immune to her charm and loves her for who she is, but naturally, Mai doesn’t realize this and has always cursed her charm. Little does she know that her charm comes from the lovely lady pictured below her…

Shieru
A Tennyo, and like Ceres, actually lives within Mai’s body. Little is known about her, but it is she that the men are attracted to.
from episode of shuro:

Ameku Michiru
A girl born from a line of Okinawa Tennyo, but no one was worried that she would return to the heavens because she’s tone deaf ^_^; She takes interest in Shuro and Kei and it is her idea that they become stars. She becomes their manager to get them noticed.
from episode of aki:

Kushima Sara
Look familiar to anyone? She is in fact, the reincarnation of Kurama, the girl who was in love with Mikagi (this is found in the Ayashi no Ceres gaiden I translated here.) She meets Aki at a young age and fall for him (while drawn to the Mikagi inside of him, she also is drawn to Aki himself).
from episode of miku (the Ayashi no Ceres sequel):

Miku (it’s not specified what they use for her last name, since Aya and Tooya aren’t legally married and Tooya never had a last name…)
Aya and Tooya’s daughter. (the one they conceived around volume 11 of the manga ^_-) Since she was conceived back when Aya had Tennyo powers and back when Tooya still had Ceres’s mana inside of him, Aya is worried that some day, Miku might develop Tennyo powers and fly back to Heaven and leave her. So Aya tries to keep Miku away from heights, even though Miku loves to be "up high" ^_^;

Shiori
One of the Tennyo’s "eggs" that was rescued off Kagami’s ship by Alec. Unlike "Chidori" and "Miori", Shiori’s capsule was not marked, so it’s a mystery who her mother (and father) is. Shiori herself is rather mysterious, and she takes a liking to Miku…
