The Curled Tails is a hairstyle in Soul Calibur IV. It consists of two pigtails, curled into tight ringlets or "drills". It has roses adorning the hair on either side. Attached to the roses are ribbons decorated with skulls. The hair is an odd brown-ish purple color when selected. This hairstyle also appears in Soul Calibur: Broken Destiny, but the color is dark red when selected instead of purple.
This is Amy's 2P hairstyle; however, it is exactly the same as her 1P hairstyle, just in a different color. It is exclusive to female characters.
