Sonnet

"The Reyvateil are suffering…I can’t just abandon them…"

- Sonnet

Sonnet is the heroine of the Ar tonelico manga, Ar Tonelico ~Arpeggio~. A third generation Reyvateil who was born in the upper world Platina. Unable to ignore the suffering of the Reyvateil, she descends from Platina in order to ascertain the location of a Hymn crystal that would halt the Reveris disease and to bring it to Masticus. Unlike normal reyvateil she has a "Hymn Code”, which is used by the tower to identify them, as she inherited the blood of the ancient pure blooded β-type Reyvateil. When she casts song magic, her songs are often about birds or wings.

Origins
She wasn’t even old enough to understand what had happened when she lost her parents, and was taken in by Masticus who she became devoted to him and served him without question. On his orders she went to seek out the hymn crystal "Soporific". When she casts song magic, her songs are often about birds or wings.

Firefly Alley
She appears before Espada and Adagio to thank them for stopping the rouge Reyvateil and then asks for his sword noting it held the Hymn crystal she was looking for. He refuses after noticing she's a Reyvateil and she proceeds to attack them until she passes out and is treated by Kauron for fatigue. After Espada storms out they learn how his parents were killed.

Nemo
They travel to the Airport City Nemo where they meet Adagio's sister, Andante. Once Adagio is dragged off, she stops some Tenba members from attacking a young Reyvateil and sings a song. The area is attacked and they chase after the culprit and learned it was Adagio's familiar, who showed them a little of the past. The group then leaves to eat, but she leaves to go outside where talks to Masticus through a earpiece. She then decides to take the sword for him. Nemo is attacked and they head towards it.

Reveris Prototype
After supressing more reyvateil they met members of the church who offered them a chance to rest. She passes out and later that night a surge woke her up. They go to find Espada fighting Kauron and after getting away she heals him, she makes it clear that he's a Virus and that the true body is in Platina. She tells him that she would like him to help stop kauron but when he refuses, she goes on her own while Adagio holds Espada back. She along with a knight fight the Reyvateil until she uses a song to shut down their connection to Ar Tonelico. Kauron then attacks her and Espada saves her and lecture her about thinking of everyone else before herself. After Kauron dies she apologizes and takes the sword and leaves for Platina.

Goodbye
Back in Platina she meets with Masticus and hands over the sword. She later discovers he created the virus and runs out before realizing that she has nowhere else to go and agrees to follow him.
