Character Setting

Edit

Hajime Aono is a first-year high school student and a former violin prodigy who rediscovers his passion for music after a traumatic family event forced him to quit.

After the Christmas concert and the start of the new year, Hajime cuts his hair short.

This change in hairstyle symbolizes his decision to get a fresh start and move forward.

Hajime is initially portrayed as introverted, listless, and somewhat gloomy.

After his father's scandal, he became apathetic and spent his days in a daze, rejecting everything associated with his past.

His fated encounter with Ritsuko reignites a spark within him.

Upon joining the Umimaku orchestra and facing his rival, Nao, his deep-seated passion for music fully reawakens, transforming him into a determined and focused musician.

Hajime is the son of the world-famous violinist, Ryuuji Aono.

Under his father's strict tutelage, he dominated various violin competitions throughout his elementary and middle school years.

However, he was deeply traumatized when his father's affair became a public scandal.

The painful scrutiny from the media and his classmates caused him to abandon the violin and reject his father completely.

As a former child prodigy, Hajime possesses exceptionally high violin skills.

Although his technique grew a bit rusty during his year-long break, he has since returned to his former prowess.

In contrast to his musical talent, he is terrible at physical education.

He also isn't a natural at academics but was able to pass the Umimaku High entrance exam through intense study with Ritsuko's help.

Ryuuji Aono

Ryuuji is Hajime's father and a genius violinist. Hajime once adored him but came to despise him after the affair scandal, quitting violin to erase his father's influence from his life.

Mother Aono

After his father left following the divorce, Hajime has been living with his mother.

Ritsuko Akine

Ritsuko is the classmate who inspired Hajime to play the violin again.

In exchange for Hajime teaching her the fundamentals of the violin, she tutored him, helping him pass the general entrance exam for Umimaku High School.

Nao Saeki

Nao is Hajime's half-brother and a formidable violin rival who swept the competition circuit while Hajime was on hiatus.

After a heated confrontation, the two fully reconciled, agreeing that their relationship as brothers and rivals transcends their shared father. They now share a healthy rivalry, pushing each other to improve.

Takeda-sensei

Hajime's middle school teacher who recommended he apply to Umimaku High School.

A Fallen Prodigy

Hajime was a celebrated violin prodigy until his father's affair scandal shattered his world.

Unable to cope with the public humiliation, he quit playing and chose to live a listless life, hoping to attend a public high school as far away from his past as possible. Following the recommendation of his teacher, Mr. Takeda, he set his sights on Umimaku High School.

The Path to a New Beginning

During his third year of middle school, Hajime injured himself in gym class and was sent to the school infirmary.

There, he discovered his classmate, Ritsuko Akine, practicing the violin. Inspired by her earnest playing, he picked up his own violin for the first time in about a year.

He and Ritsuko decided to attend Umimaku High together.

Hajime helped Ritsuko with her violin basics, and she, in turn, helped him cram for the difficult entrance exam, which he successfully passed.

Reignited Passion at Umimaku

Upon entering Umimaku High, Hajime and Ritsuko joined the prestigious orchestra club.

There, he came face-to-face with Nao Saeki, the violinist who had taken his place and won all the competitions he had abandoned. Seeing his rival in person reignited the fire for music he thought he had lost.

After a joint Christmas concert with the choir club, Hajime finds a new resolve.

He fully reconciles with Nao, and they acknowledge each other as rivals, determined to push forward on their own terms, independent of their father's legacy.

Hajime's birthday is January 1st, and he is a resident of Matsudo City.

Even after his parents divorced and his father left the family, Hajime and his mother have not changed their surname.

His voice actor is Shoya Chiba.

His violin performances in the anime are provided by Ryota Higashi.

Character Comparisons

The character of Hajime Aono from *Ao no Orchestra* shares similarities with other music-themed anime protagonists.

He is compared to Lucky Sonoda, who also has a musician father (a pianist) and a painful past connected to him. However, Lucky eventually gets a form of satisfying revenge on his father.

He also draws parallels to Hitori Gotoh. Hitori was an incredibly skilled solo guitarist but had no experience playing in a band, which led to poor evaluations in group settings. Hajime implicitly receives similar criticism about his own ensemble playing, reminding viewers of Hitori's struggles.
