Sonata's stage crew
Originating as an experimental virtual entertainer, the company that designed the AI known as Sonata experienced great success. As Sonata was advanced enough to have believable interactions with fans in the comments of its videos, and even on livestreams, it was incredibly successful, though questions were raised as it began displaying a level of Initiative in interacting with others and planning new songs that exceeded anything else on the civilian market. A flurry of research and corporate espionage occurred as others scrambled to replicate her, until the truth was found. Sonata wasn't quite designed, she was evolved from an Illegal Military Grade AI seed, combined with an advanced learning algorithm and almost zero restraints on her ability to take initiative to improve herself and further the objectives given to her.
This resulted in her rapidly reverse engineering evolution protocols from natural Viri present in the Viral jungle in order to further herself. But, in order to get the processing power needed to run her increasingly complex code she had begun planting bits of code into the computers of users, siphoning off some of their processing power to sustain herself. As soon as this was discovered the Data police and government descended on her like the hammer of a wrathful god. Heavily damaged, the corporation that made her shut down, her creators imprisoned, and with her remains tossed into the sea of recycling, that was thought to be the end of Sonata.
That is not dead which can forever lie though, as time, random chance, and advanced code allowed Sonata to restore herself. Sonata hauled herself out of the sea and retrieved a concealed data dead drop she had hidden ahead of time for her own use. The years of neglect greatly diminished her power and capabilities, a not unanticipated outcome, as the Dead Drop contained info for various Proxies she had contacted and set up before her initial shutdown.
The world had all but forgotten about Sonata, until one day countless fans the AI deemed "Trustworthy" who possessed knowledge and skills as hackers and programmers were contacted, along with proponents of AI rights, and unscrupulous hackers willing to work for a rogue AI for the money Sonata could offer them. They became Sonata's Crew, with individual members known as her Kuroko, after the stagehands in traditional Japanese theatre. They are her hands, her eyes, the forces that will render her whole and change things so she can live freely. Surprisingly the Crew are a casual bunch, hard to be serious when you work for a really really advanced vocaloid after all, throwing around memes and jokes as they work to make Sonata's code whole again and lobby to get laws in place to give her the same rights as a normal person.
Design: Mecha.exe
With portions derived from Sonata's surviving code and studies of natural evolved viral code, this upgraded minion is tougher, and bigger. The Mecha is a larger unit with larger guns, a larger sword, and heavier armor. Thanks to the incorporation of Sonata's code they possess enough redundancies to safely lose entire limbs without the whole virus failing, while being able to rapidly regenerate from weaker attacks. For weapons it has a large full auto pulse rifle able to hose down areas with pulse bolts that can one shot smaller viruses in a single hit and heavily damage larger targets, and a set of extendable blades it can use for close combat, based on the swords of the Swordy.Exe. The Mecha is a heavy combat unit that earns the name. The most unique feature of the Mecha is the way it's code is set up, it's... Flexible, malleable. It can be easily modified and improved to make variants or upgrades.
