MariaKhun

MariaKhun is the family ship between Khun Aguero Agnis and Khun Maria Jahad from the Tower of God fandom.

Anime
Aguero and Maria are two of Khun Eduan's many children, born from different, unrelated mothers. The majority of their backstory has not been revealed, but there is enough to conclude that they are currently not on friendly terms.

According to Aguero, Maria was a kind and trusting woman, traits that one would say are rare in a competitive family such as the Khun's. Aguero cared deeply for her, even going as far as help Maria become one of Jahad's Princesses. However, in doing so, Aguero betrayed his own blood-family. After getting the status of Princess, Aguero was abandoned and thrown out of the Khun family since his side of the family were "failures" for harboring a woman who failed to become a Princess (Kiseia).

It is unknown if Maria betrayed Aguero on purpose, or if it was even her choice to begin with. After suffering a bitter betrayal, Aguero moved on and started to climb the tower. Interestingly, he doesn't seem to resent Maria in any way despite her abandoning him, as shown during the Door Test where he has a flashback of her saying "My Aguero..." before being violently reminded by his mother to never trust anyone. Maria's betrayal only strengthened Aguero's distrustful and doubt towards others, even when said others are trying to help.

After Aguero was discarded from the Khun Family, the other members of the family started to spread rumors. The rumors said that Aguero and Maria might've been lovers and therefore in an incestuous relationship. There is no proof/confirmation they were, however, other than rumors the other members of the family spread about them.

Fanon
Fanworks generally delve deeper into their backstory and are essentially canon-divergent since there is so little that is actually known about their backstories. Many like to depict Maria has an 'older sister' figure towards Aguero, especially after hearing how his mother and sister treated him. Other fanworks may highlight the parallels between MariaKhun and RachBam's relationships, mainly how both females betrayed the boys yet they both seem to retain at least some semblance of care for the girls.

Due to the canonical story, angst is a common running tag in MariaKhun fanworks, since both characters seem to carry some guilt for betraying their loved ones.

It is the 10th most written relationship on AO3.
