Wishful Finale - Aria

When the Angels of Delusion were first formed, the three young girls made a wish: to create a "Delusional Stage" where audiences could lose themselves, forget their troubles, and bask in the joy delivered through song and smiles.
And Aria, model "A-H0L0," was the most unique member of this warm vision. On the path to becoming an idol, a paradox has always lingered in her heart.
She expresses emotion, yet questions whether those emotions are real; she was born from steel and code, yet yearns to sing symphonies of flesh and soul. She's a weapon by design, with annihilation hardwired into her logic, but she is also a singer, her core pulsing with impossible desire.
Perhaps the divide between those two natures was never truly erased, only carefully tucked away into the shadows after she found the light.
Until external stigma spread like corrosion, until malicious whispers nurtured those buried shadows into monstrous dread... She realized with horror that her uncontrollable combat instinct was about to become the greatest threat to her "Delusion," and the past known as the "Mirage Archer Unit" took control of her body. Energy gathered in her palms, condensing into cold, razor-sharp blades. This was nothing like her imperfect dances of before. She leapt, cleaved downward, and thrust forward. The blades of light obeyed her will flawlessly, exact and efficient, without a trace of waste. Emotion was cut away, each strike numb and mechanical, until the delusional stage lay in ruins.
The song meant to hold everything together had grown thin and weak.
Thus the paradox began to converge — she would use her own silence in exchange for the angels' eternal protection.
"The stage... it's so warm. Even though my voice lacks the warmth of a heartbeat..."
"But it's okay. You'll keep singing."
"Keep going for me. Witness in my stead, what this cold heart never knew — the glow of that delusional rainbow."

Finale's Wish [sic] is proficient in multiple attack methods. When facing formidable enemies, it activates excess power output to generate Energy, compressing it into a nearly solid concentrated Energy blade. With highly threatening offensive pressure, it unleashes continuous slashes to sweep the battlefield. When energy reaches its threshold, the light blade enter an overload state, and the escaping energy disrupts enemy movement and reactions, creating an opening for the next decisive assault.
