Rei Togetsu

Rei is a modest and polite yet earnest girl who seeks to experience more in life. Although Rei attends a fairly regular school, it has been shown through various activities, anime, and extras that her

Yamato Nadeshiko skills are so developed that even highly educated and well-mannered girls like Haruna and Esora are impressed by her. For example, when Haruna needed someone as "perfect" as Miyu to gain communication experience and practice giving her a present for White Day, other girls brought Rei to help her out.

Due to her classical upbringing as a "perfect lady", Rei was often deprived of some of the usual experiences for a girl of her age, so she is often quite flustered by things that seem completely ordinary to others. She becomes excited about the idea of having a sleepover with Muni and later Maho, and also perceives playing video games, eating fast food, staying up late while eating sweets, and even building snowmen with everyone in Happy Around! and Lyrical Lily[4] as very exciting events in her life. At some point, Muni even has to warn her that overindulging herself on chips and snacks can be harmful. Another example is that she is unfamiliar with various technologies to the point that Muni describes her as being from the "stone age".

Rei has blueish-black hair and teal colored eyes. Her hair reaches down to her waist, and part of it is pulled back with a white bow. After the 3.0.0 update in Groovy Mix, her hair became curlier.
