Puriel Crystallight - Angel (TIS) (Patreon)

She is Erebus' aunt. One of the high angels of the light dimension.

A thousand years ago, she went to the human world to help and protect Erebus upon her mother's request. But the situation was worse than she thought and she ended up trapped in the crystal.

Eventually, she met Ethan, who was trying to free her from the crystal and mistook him as Erebus.
