Lupita's character is reportedly inspired partially by a friend of the writers, named Lupita Martínez. Lupita is sweet and quiet, but she has a complicated relationship with family and puts too much pressure on herself because of her scholarship and because she doesn't want to disappoint her aunt. This often leads to Lupita angrily telling people off whenever things are too much to her which then will make her rebellious. However, she likes to be helpful. She's part of RBD alongside Mía, Miguel, Diego, Roberta, and Giovanni, and she comes up with the band's name. She's a victim of La Logia, a secret society that strives to keep the school 'pure' and 'clean' of scholarship students.
