Arietta Antiphon/History
History
She is the child of Gaius Antiphon and Miria, a Noise Beast who chose to live in the human world with her husband. Because of her being half-Noise Beast, Arietta has a strong connection to the World of Music and finds it nearly impossible to compose music. Whenever she tried, her mind was taken over by the influence of the other world and unwittingly played an already extant piece of music.
For her birthday, Gaius gave Arietta a copy of their latest AI prototype, Joker. Though initially confused, she accepted the gift and became close friends with the AI.
When Arietta learned that she was unable to compose, Beyond insisted on helping her. This led to them going into the basement of the Antiphon building to investigate the portal to the World of Music. When they arrived, the portal reacted, and Arietta was briefly able to compose. An otherworldly entity entered into Arietta's eye, and attempted to lure her into the Void. Beyond forcibly shut down the portal, and Arietta lost her right eye in this incident.
Beyond and Arietta decide to use the NOISZ to harvest energy in order to restore their bodies and repair the boundary between worlds, stealing it and running from home with Remora. She also had a neural chip installed in her brain by Remora to communicate with Joker.
After multiple failures to acquire enough energy with the original NOISZ, Arietta contemplated developing the mass-production prototypes further. Unfortunately, the mass-production prototypes possessed a consumption rate more than thirty times higher than the original unit, making them useless. Alpha offered to help her, and despite knowing the danger, Arietta couldn't resist, desperate to help her sister no matter what.
As they gather energy, Gaius learns of what happened and steals the NOISZ back when another user falls to a Noise Beast. As he uses the NOISZ to seperate the worlds, Beyond and Arietta's corruption begins to act strangely. As they struggle to plan what to do next, Arietta receives a vision of the future in a dream; of STΔRLIVHT being attacked by a Noise Beast but being saved by the group, of them defeating Gaius Antiphon with great sacrifice, and of the last NOISZ user, who seemingly defeats Alpha, but she manages to escape by faking her death.
After she and Remora confirm the existence of STΔRLIVHT, they go to their HI-LIVE performance where a Noise Beast attacks as predicted. Now knowing for certain the dreams were visions of the future, Arietta and Remora create a plan to defeat both Gaius and Alpha with STΔRLIVHT by having Joker take Arietta's place in the world and act as STΔRLIVHT's producer to use the Final Burst against Gaius, with Arietta acting as Beyond in the true Beyond's place.
After Gaius' death, Arietta erases her memory of the final battle to keep Alpha from being able to read her mind and learn that STΔRLIVHT is alive.
