The final version that I'm willing to put. The story has changed a bit and permanently will be.
Ayana's life changed completely from running away from home and now captured by Star Assault. Trained as a war prisoner, Ayana does her best to stay alive and keep herself tip top shape. She has a hard down life of loneliness due to being locked up and continuous watch on her. Ayana is also an Arch demon, a rare breed that is able to evolve abilities, shape-shift and absorb powers through touch, kiss and etc.
It does makes her powerful but at the same time it also tires herself out if used too much power and corrupts her body. She does have multiple ways to gain energy through sexual intercourse or using dark energy and absorb them. Most of the time she can gain small amount of energy through kissing, but Ayana's hatred towards men causes her to avoid them. Pretty much Ayana is following towards lesbian love, but if pressured enough she could able to find love towards men maybe... possibly not.
