The third costume of Phase Connect's Rinkou Ashelia, as seen in post #8153694.
It consists of fake head wings, a white crop top with belts forming a criss-cross halter and mismatched detached sleeves (the left sleeve having black and white stripes and the right being blue), white bloomers with blue frills and a black belt, torn and mismatched leggings, white leg warmers with fake wings on the ankles and blue and white sneakers.
Her official hairstyle for this outfit is a wolf cut with blue-streaked, chest-length locks and bangs covering her left eye.
