>>95840549The white-haired little girl, named Illyasviel von Einzbern, or Illya for short, is actually a half-homunculus whose true magical powers and parts of her soul were magically sealed away by her homunculus mom and mercenary wizard dad in infancy. A decade later, after becoming a magical girl from wielding one of Wizard Marshal's two Kaleidosticks, the sealed-away parts separate themselves from her and take on the form of a near-identical girl, who is then named Chloe, but is most often called Kuro (Chloe is pronounced Kuroe in Japanese, and kuro is the Japanese word for black). This division was made possible by Illya's use of a "class card," a card-shaped magical container for a degraded copy of a powerful spirit. The spirit in question was, unbeknownst to Illya, that of her adoptive Japanese ginger brother's older superpowered self, who has white white hair and brown skin. The buried parts of Illya's being that constituted Kuro, hijacked the class card and substantiated themselves as a person, using the class card as a foundation for the materialization.
To not fade away, Kuro has to frequently replenish her reserves of magical energy, with her method of choice for doing so being to French kiss other girls.
