幾原邦彦
Takeuchi based Rei on her own personal experience as a miko. Originally designed with her own unique outfit, when Takeuchi decided to give all of the Guardians identical outfits, Rei's high heels were the only aspect that was carried over. A cold and aloof character in the manga, her personality was drastically changed in the anime adaptation at the behest of Kunihiko Ikuhara, where she became fiery and hotheaded.
