Kacuy

Kacuy once was an orphan, not much went on in her life. She spent her days like any other person would. Well, not entirely. Most spent them in school but the orphanage she was in couldn't afford such a thing. So she instead spent her time fooling around or mastering certain arts. Mostly trying to master the art of martial arts, but failing desperately. When not doing that though, she'd be joining her brother, Dimo, in messing around with other people. Life was great, and nobody could say she didn't have a good life.
(wouldn't be me if I didn't 'fix' this)
Then one day it wasn't so great when turmoil struck the town and Project Mirror was secretly a thing. She was taken, both her and her brother, to participate in Project Mirror. Dimo didn't survive the ruthless tests that went on, and Kacuy gained a sickening voice in her head that wanted her dead. Or maybe it didn't, but simply wanted to die itself.
She led a rebellious attack against Project Mirror and started a mass uprising which was called by other participants who got out, Shatter the Mirror. Some other however called it, Kacuy's Rebellion, to honor how she was the one who actually got them out.
(Wouldn't be me if this didn't happen) After a few months spent with Teo and Grim, and them being there for her to deal with the sick voice, she decided that she had no intention to deal with it forever. And if it really wanted to die that bad, and so did she, why should she stop it?
