Rei has very long blonde hair, which she sometimes ties in two high tails and blue-grey eyes. Like all AKB0048 members she has heart shaped sparkles in her hair and eyes. She is always wearing necklace she got from her sister before she went to AKB0048 audition. She is wearing diffrent clothes, but she rearly wears skirts or dresses when she isn't on stage.
Rei never had a lot of friends, she usually spend time alone or with her family. She didn't fell lonely but she often wished she had some real friends. She is very kind and hates unfair things. She can sometimes control herself but can also get angry easily. She loved music and singing since when she was young kid. She really admires her older sister. She loves drawing and writing stories, but this is something she didn't tell anyone, because she gets emberased if someone else see her stories or drawings.
Rei was born on Hikaristar, planet that used to be one of planets that weren't under entertainment ban and music was very important part of their life, until it was suddenly put under entertainment ban. She lived with her grandmother, parents and older sister. Rei didn't have a lot of friends, usually she spent time with her family or alone. She always admired her older sister who was also part of AKB0048 and became Maeda Atsuko 18th. Rei missed her sister a lot when she wasn't at home, but she was happy for her. When their parents died in accident, Rei's sister gradutated from 00, even though she wasn't succesor for long time, because she wanted to take care of her sister and sick grandmother.
Rei knew about AKB all of her life, since Hikaristar used to be planet where music is very important. At that time she didn't really think about joining them. She thought about that for the first time, when her older sister joined AKB but when their parents died Rei stopped thinking about that for a while. She remembered her dream again when application for 150th generation understudies were opened but she wasn't sure if she should take audition, because she thought it won't be fair for her to achieve this dream even though her sister wasn't able to enjoy it for long time. When her sister told her that she should join AKB if that's her dream she decided that she'll take audition.
Audition & joining AKB0048 Edit
Rei passed audition and became part of 150th generation. She also became good friends with her roommates Hotaru and Yumeko.
Live on Atamistar Edit
Rei sang duo version of Itoshisa no Accel together with Akano at live on Atamistar which made her slightly nervous but also happy.
152nd generation auditions Edit
At 152nd generation auditions Rei was teaching girls at hand to hand combat along with Sayaka and Akano. She noticed Chiyo, Nami and Tomoko and was sure that they'll pass audition and become part of 152nd generation when she was watching them train. When she and Sayaka realised they are taking they training too far they made them take rest and decided to bring robots for training. At lunch she sat next to auditioneers Hibiki and Diana and was later joined by Hotaru, Yumeko, Tomorin and Chiyo. When she noticed Tomoko leaving dinning room she went after her and talked to her. She later returned to the same table.
