FurHisu

FurHisu is the family ship between Frieda Reiss and Historia Reiss from the Attack on Titan fandom.

Canon
Frieda and Historia are both step-sisters, being born from the same father, but not the same mother. Frieda would usually go visit Historia, and they became close. Frieda taught Historia how to read and write, and kept her company when she was alone, to which the latter is extremely grateful for. She was even willing to kill Eren, her comrade, after learning what his father did to her.

Historia has mentioned that Frieda would start acting like a completely different person, and that she'd called themselves "devils". When she told Eren that when she saw someone crying, saying they wish they weren't born; she wanted to tell them that wasn't true. Both Frieda and Ymir could be seen, showing that the two of them were possibly the two people she had loved the most.

Historia claimed that she wanted to be like Frieda when she grew up, to which Frieda blushes and hugs her, the two laughing. After, saddened to leave her, Frieda erases Historia's memories and takes her leave, never going back.

Fanon
Due to Frieda and Historia having a strong bond, FurHisu are greatly shipped as a family, and in fanfictions, Frieda acts like a somewhat mother to Historia.
