Son of an English father and a Spanish mother. He is a boy of medium height, blond hair, with a fringe that almost covered one eye, and behind which he sometimes hid, due to his shyness.

Darío's father had abandoned Darío and his mother for no apparent reason, so his mother had to return from Gibraltar to La Línea, since they could no longer maintain the standard of living that they had enjoyed until then. She was forced to look for a job, since, when she met Darío's father, she had abandoned her studies, with promises of a comfortable life in exchange for marrying him.
