Varis Denki

Origin
She was born in the underground city of Neo-Tokyo III, one of humanities last bastions of civilization during the Greatest War. She was born quite prematurely and needed small cybernetic enhancements to keep her alive at an early age. Her biological parents are unknown to her as she was raised in an orphanage. As she grew up, she became very influenced in electronics and technology. After all, many of her caretakers were robotic and she looked up to them like a real mother.

Trans-humanist
During her years of education she was introduced to the cybersphere, an alternate version of the internet where you can plug your brain directly into. You can travel through it as if you're in a VR game or in a dream. This led her to find communities of trans-humanists whose beliefs helped her views on technology and science solidify more.

Cybernetics
Being a trans-humanist led her into the black market of cybernetic enhancements. Although risky, she had many surgeries to replace her organic limbs. She even had a surgery to plug her glasses into a more portable version of the cybersphere, that way she could be on the internet wherever she went. She even bought synthetic transplant organs which she sold on the black market to field nurses.

Insomnia
Being on the cybersphere constantly has some negative effects. First of all, she was on the cybersphere so much, she would fall asleep many times throughout the day just doing regular things. She had many problems trying to stay asleep during the night, but would sleep a lot during the day to try and catch up. Sleeping had become one of her other favorite hobbies when she wasn't hacking random druggies in an allyway. When she dreamt, she programmed her goggles to simulate what the surface looked like. She loved to walk around and explore the ruins of an earlier human history. She didn't have much care for leaving underground, but she did find it interesting enough to entertain her when she was dreaming.

Hacking
Being on the cybersphere constantly would of course lead to new skills. Even though she knew it was illegal, she would download skills like hacking directly into her brain. Hacking became one of her favorite hobbies, because she loved messing with people, but not in a harmful way. The least she could do to a random stranger was hack their goggles to say profanities and play annoying memes.

Fringeria
After the war's beginning, she began seeing more into the internet. She of course hacked into some fringerian networks to see what they were truly doing. She saw the horrors of the Neo-Holocaust, and being a trans-humanist, it made her blood boil. She believed that humanity has the freedom to digitally evolve to whatever being they so chose, whether that be a hologram, AI, or just somebody who wants robot limbs. The Fringerians saw humanity as an opportunity to exploit into soldiers, and they turned many unwilling men, women, and children into cyborgs to use at their expense.

Hacking Rebellion
This awful truth helped her lead a rebellion against the governing fringerian police which had subjugated many of the underground citites. She taught people how to hack into their buildings without authorization. It helped start a revolution in the underground cities, and became a leader of the Hacking Rebellion.
