Iziuel

Background
When Shiro was sneaking in the 3rd floor of the Elven Royal Library, noticed her and found a familiar feeling within her. After a discussion with Nimue it was observed that seems to have lost her memories after being used a 'battery' for too long.

and Shiro did a Ruler Contract to allow entry in Shiro's Mana Realm.

She is a former member of the royal spirit council.

First Appearance
Suspended in the air while being entwined by numerous vines, a feeble girl could be seen barely responding while her wings were crippled behind her. Not only that, they could see that her eyes seemed hollow despite her eyelids being closed. It was as if there were no eyeballs behind them.
