Luna

Luna Rivera (also known as Tía Luna) is the wife of Tío Óscar, daughter-in-law of Hélga and Papá Nicholás, the mother of Nicholás "Nick" Rivera, sister-in-law of Imelda and Héctor and the aunt of Coco and Nikki Rivera. Like her sister-in-law, Luna disapproves of her niece travelling to Mariachi Plaza and berates Nikki for going down there and tells her that she must listen to her mother.

Later, Luna is present when Nikki announces her father was a musician and wishes to be like him.

Nikki says she loves her aunt but hates it when she parents her when it is her mother's job and not Luna's.
