Eve

Eve is an artificial human capable of reshaping her body and genes using nanomachines embedded in her DNA. After escaping her creator's orders to eliminate her, she began navigating human emotions in a new world. She initially formed a rivalry with Train as they both competed for Sven's affection, though their relationship eventually grew more complex. Eve possesses a sharp wit and can memorize books at lightning speed, using this knowledge to enhance her abilities. While Train calls her "Little Princess," her true motivations are driven by an intense curiosity and a desire to understand human connection.
