She's introverted, quiet and somewhat shy, but is also friendly, caring and helpful. She's dutiful and attends to her obligations as she should. She has a hidden mischievous, fun side and likes science-fiction media, such as movies and video games. Though others find her a bit weird, quirky and offputting, Rei rarely wishes ill will on others, unless they've threatened her friends. Rei's parents were Akio and Keiko Ayanami, two prominent engineers. They died in an accident when she was young.
