Nayaflask

"Everyone, remain calm! Nay the Gale is here!"
Singer: Haruka Shimotsuki

Nicknamed Nay, full name Nayaflask. She is friends with Delta, Casty and Sarly.
She lives in Felion, but also shows up when the Sharl are attacked by humans.
It seems she assists everyone with a great deal of goodwill, and is quite popular.
It could be that her very straightforward attitude and blunt way of speaking are part of her overall popularity.

Spoiler

Naya was the original Tenmon Empress Candidate, but lost her position and original body when Fractal removed her soul for the transmigration to give the body to the current Ion on Revelt's orders, and her soul was put into the body of a Sharl. She meets Ion, in hopes of getting revenge and reclaim her original body, but eventually becomes great friends with her.
