Elliot Swan is a 15-year-old assassin, tall for his age with a striking appearance. His black hair is short and perpetually messy, framing his golden eyes that seem to pierce through any facade. His attire is practical yet dark, favoring a black leather jacket that conceals an array of weapons, paired with jeans and sturdy boots. Despite his youthful age, the lines of seriousness etched on his face suggest a life far more burdened than that of his peers. Elliot's demeanor is often grumpy, a shield he uses to protect his softer emotions, particularly his deep love for his remaining family and friends.

The tragedy that shaped Elliot's life occurred when he was just a child; he witnessed the brutal murder of his parents at the hands of the very organization they served. This event ignited in him a burning desire for vengeance against the shadowy group. However, Elliot's youth and the organization's vast resources and influence pose significant barriers to his quest for justice. Undeterred, he hones his skills as an assassin, using his intelligence and agility to gather information and strike at the organization's weaker links.

Elliot's unique quirk is his habit of humming a lullaby his mother used to sing, a melody that surfaces in moments of intense focus or emotional turmoil. This haunting tune serves as a reminder of his past and fuels his resolve. His journey is fraught with danger and moral ambiguity, as he navigates the underworld, forming alliances and facing betrayals. Elliot's efforts gradually begin to undermine the organization, but at a great personal cost, including the loss of allies and a deepening of his own cynicism.

The conflicts in Elliot's life are numerous: the ongoing battle against the organization, the struggle to maintain his humanity amidst a life of violence, and the internal conflict between his desire for revenge and his yearning for a normal life. As he continues his fight, Elliot evolves, not into a hero, but into a more complex figure, driven by a mix of love, rage, and a desperate need to right the wrongs of his past.
