Maria Torres is the mother of Antonio Torres and wife of Alejandro Torres. Her real name was Maria Hightower when her and her family lived in England. Maria is a dangerous and obsessive woman who tortures her son. Tsukumojuku Kato describes Maria's love for her son as hardly natural.

Every year on June 16th since Antonio was a baby, Maria peels off his skin bit by bit while leaving his blood, bones, and flesh intact. She then carefully places the pieces together, treats them with a thin-coating of oil to prevent them from drying out, seals them with medical adhesive, and sews the pieces together with very fine thread. Antonio's hair that was shed from prior months would be placed on top of the head of her creation to complete the full body work of art, which she called "This Year's Antonio".

She adapts her technique over time, while Antonio's body adapts to survive the pain. Rather than taking photographs of her child like a normal person, Maria obsessed over the texture of Antonio's skin, and wanted to preserve it each year. Before the police takes her away after they discover Antonio's corpse, Maria rubs her cheek against the final "This Year's Antonio" she created, desperate to savor her last moments with her art.
