Rhajrrin

Corhajat is the non-binary ship between Corrin and Rhajat from the Fire Emblem fandom.

Canon
Rhajat is the daughter of Hayato, a member of the army of Corrin. Like the other children of Fates, Rhajat was placed in the Deeprealms for her protection, resulting on her accelarated growning. One day, she nearly fell off a cliff, only to be saved by Corrin who was visiting her Deeprealm at the time. This became a turning point in her life personality wise. After that, she falls in love with Corrin and becames somewhat obsessed with them.

In her death quote, Rhajat reveals that she sees herself and Corrin's reincarnation in a distant future, in a desert, referencing Tharja, who was obsessed with Corrin's future reincarnation, Robin, in Awakening. If Corrin's gender is male, they will have a daughter, named Kana. If Corrin is female, they will stay childless but Rhajat states that she sees the creatures that she summons as her children.

Fanon
Rhajat is the first female character that can canonicaly marry a girl, in this case, female Corrin. Curiously, female Corrin can also be Rhajat's mother in different timelines if she marries Hayato.
