Rei is a student of Venus Ark and is also the headmistress' secretary. She was born in America. Her family background allowed her to try out multiple activities and excel at each of them.
Rei first met Elza at a modeling show where Elza saw right through her mask and told her that there was no passion or radiance in her eyes. Elza showed Rei what it was like to be radiating. Elza then invites Rei to join her to fulfill her dream. Her support for Elza stemmed from the inspiration she received from Elza's dream.
