Yashio Rui

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

Background
Rui is a talented violinist who has played the violin ever since she was young. However, at one point in her childhood, she lost in a competition, came to the conclusion that she had no true talent despite all the effort she put in and that playing the violin was completely meaningless. As a result, Rui quit participating in competitions and stopped playing the violin.

She also used to be friends with Rinko, and their parents were friends as well. The two used to participate in the same competitions together and would talk just how much they love music. Before Rui's changing point happened, she was shocked to find out Rinko stopped participating in competitions.

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

Appearance
Rui has dark brown hair that goes just past chin-length 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. Despite being a first-year, Rui looks mature for her age.

Personality
Rui is a talented individual who is always at the top of her class. She has a dry personality and is always aiming for top results, and speaks in a polite manner. She is very logical and realistic, but can also be blunt when it comes to her opinions, especially about talents or music. In addition to her logical nature, she plans out her days and schedules very thoroughly, and as such, doesn't understand things like people hanging out or taking detours after school. Due to her stoic and composed look, Rui says that people tend to think she's angry even when she's not.

In reality, the reason why Rui does not choose to immerse herself in activities she deems meaningless is because she is afraid of getting hurt and disappointed in the same way she did after placing 5th in the competition that made her decide she doesn't have true talent. She felt that no matter how hard she practiced, no matter how much she felt like she loved music, her talents weren't acknowledged because she didn't have it in the first place. This is also why she developed a cut-throat attitude and refuses to prioritize her emotions similarly to the other Morfonica members.

Despite having different's personality, Rui later befriending Seta Kaoru because they appriciated arts.
