She has several ongoing titles: Mirror with Malaysian artist Hwei Lim and Pretty Deadly with American writer Kelly Sue Deconnick.

[4] As a young adult, Ríos attended University of A Coruña for architecture and afterwards worked as an architect for a few years while publishing comics on the side in fanzines.

[5] In the same year Ríos resigned from architecture, she participated in Lingua Comica, a transnational comics workshop program funded by the Asia-Europe Foundation (ASEF).

Ríos has related in interviews that she did not feel like a real comics artist until she was selected for the program alongside Hwei Lim, with whom she currently co-creates Mirror.

This appeared in Island magazine, a monthly comics anthology published from 2015 to 2017, which Ríos co-edited and contributed to with Brandon Graham.
