Rei is the leader of the Seven Sages. But this title seems to be meaningless, as she is teased on a near daily basis by the other six members of the Sages and sent to do pitiful work. She also has a counterpart present in the Hyperdimension, doing civic actions. Rei seems to be the very sensitive, gentle type of character who somehow manages to handle being bullied, teased, and harassed on a daily basis very well. She tries to keep things in order, but she seems to be very pathetic, according to others. She has a lot of trouble speaking decently in front of people and lacks any actual powers. She has barely any confidence, possibly none at all, and is always fearful. In her HDD form, Rei is certifiably insane, incredibly arrogant, and downright rude. After the fall of her nation, Tari, she developed the belief that because she failed as a CPU, all CPUs will fail. The traits of her HDD form can sometimes leak into her human form. At the end of the game, she is able to actively derive confidence from her HDD personality without becoming insane. She used to be the nation Tari's CPU. (Source: Wikipedia)
