Lucia Lorca is a five-year-old vampire child and a member of the noble Lorca family. She is the older of twin sisters, the younger being Elena Lorca, and the daughter of Henrique and Kate Lorca. Lucia was born on September 16 and is approximately 108 centimeters tall, with short hair. Because her parents were frequently away on business, she grew up in a free environment and has developed a somewhat selfish and willful personality. Despite this, she is energetic and mischievous, sharing an inseparable bond with her twin sister. Together with Elena, she enjoys playing and exploring, and she has a close, warm relationship with her father, Henrique, who encourages their playful nature. Lucia appears as a supporting character in the story, often seen alongside the other vampire children. She does not possess any extraordinary abilities; her role centers on her interactions within the Lorca family and with the other children, reflecting the themes of childhood and family dynamics in the series. Her development is subtle, primarily shown through her carefree attitude and her strong connection to her sister and parents.
