Rafil

Rafil is the fourth unit of Flügel, and a sister figure of Jibril. While never stated, she does hold some great influence over other Flügel and their forces, the Phantasma Avant Heim, and even power equal to or over Jibril and Azril in the political sense. It is unknown however if she resides upon the Council of Eighteen Wings.
