Miliras are a race of warmongering people with angelic appearance, complete with rings of light atop their head and white colored wings growing from their waist. In battles they command mechanoids/gynoids called 'Milian' which uses naming scheme based on chess pieces, and uses large area-of-attack skills tied to their weapons.
