Yashio Rui is a first-year student at Tsukinomori Girls' Academy and the violinist and composer of Morfonica.


Rui is a talented violinist who has played the violin ever since she was young. However, at some point in her life, she lost in a competition against a certain pianist, came to the conclusion that she has no true talent and that playing the violin is completely meaningless. As a result, Rui quit participating in competitions and stopped playing the violin.

Rui is also a member of Tsukinomori Girls' Academy's student council. She initially tagged to Morfonica's band practices only because they needed someone from the student council to monitor their activities, before the other girls manage to convince her to join the band.


Rui has just past chin-length, dark brown hair and thin, brownish-red eyes. Her bangs are parted to her left and go down past her chin. Part of her bangs goes between her eyes, down to the base of her nose.


Rui is a talented individual who is always at the top of her class. She has a dry personality and always aims to be on top, and speaks in a polite manner. She is very logical and a realist, but can also be blunt when it comes to her opinions, especially if it's about talents or music. Due to her stoic and composed look, she says that people tend to think she's angry even when she's not.
