Rosina/Story

When Rosina is asked to teach Myne to play the harspiel, she was overjoyed and immediately gives consent to becoming Myne's teacher. Due to her previous time spent as Christine's retainer, Rosina's expectations and ideas of her duties as Myne's retainers differ from what is expected of her. That led to disputes among her attendants which is followed by a meeting. It turns out that Rosina thought of herself as more special than the other grey robed priests and shrine maidens because of her talents for the arts.

When Myne tells her that she has to do chores in addition to teaching her music, she can't understand why any blue shrine maiden could ever make such outlandish demands. Myne gives her one day to decide whether she will comply or retire from her service and move back to the orphanage.

At first Rosina is devastated of the "strange" demands that Myne makes of her, but after a talk with Wilma she realizes that it was actually Christine who was the odd one and that Myne's treatment of her retainers is actually closer to normal in noble society. Albeit initially still reluctant she decides to stay Myne's attendant and promises to do her chores.

Myne assigns Rosina to help Fran with doing paperwork besides her duties as Myne's teacher. Myne respects Rosina's attitude towards music and her desire to keep her hands as unscathed from physical work as possible. She is also forbidden from playing her instrument too late into the night, so that the other attendants can get sufficient sleep. While teaching Myne the Harspiel they begin to transcribe songs Myne remembered from her Urano days. Rosina enjoys every new song she can grasp. That's why Myne presented her a small collection of songs when she comes of age that was transcribed by Ferdinand.

After Myne's death, Rozemyne hired her as a personal musician as every noble had one themselves. She asked Rosina who happily accepted. She was then bought by Rozemyne leaving her status as orphan behind to become what she dreamed of being: Rozemyne's personal musician.

Christine had planned to come back and buy Rosina when she graduated from the Royal Academy. But surprisingly she saw Rosina being Rozemyne's personal musician. After they talked a bit and Rosina talking to Rozemyne, Rosina decided to stay with Rozemyne as her personal musician who was relieved by Rosina's decision.

Spoiler for Part 4 Volume 2 When Rozemyne attends the Royal Academy Rosina accompanies her. When Rozemyne's songs catch the attention of the music teachers, Rosina is called upon to perform those songs at a tea-party with the professors and even the second Prince of the country, who surprisingly chose to attend.
