Maria is Carlos's younger sister.
After her parents died in a house fire, she developed Reverie Syndrome and falls into a coma because of the disease. Originally Carlos believed that his sister's illness was caused by carbon monoxide poisoning. Carlos is unable to pay for her treatment because she lacks insurance.
Carlos decides to participate in the Dcom testing in order to get the money needed to help cure her.
Zero Time Dilemma
In the CQD-END: 2, Maria survives her illness. It is unknown how she was cured, but it is possible Carlos used the money he got from being a participant in Dcom, or if preventing the apocalypse cured Maria's Reverie Syndrome. Maria becomes a SHIFTer and plans on going to Akane and Junpei's future wedding. It is unknown if she joins Crash Keys as well.
