Sarah Coppola, a researcher dedicated to unraveling the enigmatic properties of Exotic Matter (XM)—a substance altering human cognition—emerges as the lone survivor of a cataclysmic lab explosion at Hulong Transglobal. The corporation clandestinely pursues dominion over XM to manipulate populations. The blast erases her memories while awakening latent XM-linked abilities, enabling her to detect imperceptible portals and energy fields invisible to ordinary perception.

Prior to the disaster, her whistleblowing efforts to expose Hulong’s unethical XM experiments made her a target of rival clandestine factions. Post-accident, she forges an alliance with Makoto Midorikawa, a psychometric investigator, to dismantle the conspiracy. Their bond thrives on interdependence, yet her fractured recollections strain their mission.

Hunted relentlessly by agents of the Enlightened and Resistance factions—each intent on weaponizing her knowledge—Sarah’s symbiosis with XM cements her as a linchpin in the conflict. Her visions pierce the conspiracy’s veiled machinations, guiding their pursuit of truth.

Her past as a Hulong scientist involved uncovering XM’s perilous potential. The explosion not only obliterates her history but unlocks her dormant sensitivity, aligning her with fellow “Sensitives.” Her journey orbits reclaiming her shattered identity, mastering her evolving capacities, and confronting the moral abyss of XM exploitation.

Though physically marked by blonde hair and blue eyes, these traits remain peripheral to her narrative weight. Her dynamic with allies—including a guarded ex-mercenary turned protector—underscores her pivotal role in the escalating battle for XM’s fate.
