In a dark, gritty world where souls are bought, sold, and traded as currency, Aria is a cursed soul keeper, tasked with protecting and guiding souls to their final resting place. Her curse allows her to see and interact with souls, but it also makes her a target for those who would exploit her power for their own gain.
When Aria's younger sister, Lyra, falls ill and her soul is stolen by a powerful and malevolent entity known as the Soul Collector, Aria must navigate the treacherous underworld to save her sister's soul before it's traded away forever. With time running out and danger lurking around every corner, Aria reluctantly teams up with Nox, a mysterious and morally ambiguous soul trader, who offers to help her in exchange for a favor.
As Aria descends deeper into the underworld, she uncovers a web of corruption and deceit that threatens to unravel the very fabric of her society. She must confront dangerous criminals, corrupt politicians, and otherworldly beings in her quest to save her sister's soul. Along the way, she begins to question the true nature of souls and the morality of the soul trade itself.
With Nox's help, Aria infiltrates the Soul Collector's inner circle and discovers a shocking truth about her own cursed existence. Faced with an impossible choice, Aria must decide whether to embrace her curse and the power it grants her, or to reject it and risk losing her sister's soul forever.
In a thrilling climax, Aria confronts the Soul Collector and fights to reclaim her sister's soul, but at a terrible cost. In the end, she must grapple with the consequences of her actions and the realization that in a world where souls are currency, no one is truly innocent.
