Rei doesn’t want to be seen as a burden to her father, and often blames herself for things that aren’t her fault.

History
As a young child, Rei idolized her mother Tomoyo Aragaki. Tragically, Tomoyo died when Rei was very young and she was heartbroken, but she was slightly cheered up when her grandmother Mari Aragaki gave her a rare talking bird from South America that Rei named Big Bird. Seeing Jotaro Aragaki's distress after her mother’s death, a young Rei resolved to smile no matter what and take on all the tasks her mother once did around the house.
