Ruruko Nimura is a second-year high school student at Kuoh Academy and one of Sona Sitri's Pawns.


Ruruko is a short girl with brown hair in long twin ponytails and green eyes. She wears a pair of green clips in her hair and she also wears striped green stockings.


Ruruko had a crush on Genshirou Saji and had a love rivalry with her senior Momo Hanakai, who is also in love with Saji, until she later decided to let go of her love for Saji. She has a hot-headed personality like Xenovia, wanting to solve problems through violence, rather than negotiation. She also has a delinquent side to her, as shown when she calls Xenovia "Boss" in the tone of an underling from a gang.


Ruruko by chance, happened to learn about Sona and her peerage being devils and willingly asked to be reincarnated into her peerage. Sona did so and she joined the Student Council in the process. Her crush on Saji began when he started giving lots of help once he started doing Student Council work.
