Description
Alita Forland, second child of the late King Forland, lived as a princess until a coup orchestrated by scientist Dr. Akamashi killed her father and forced her flight from the castle. Fleeing into a border forest, she plummeted off a cliff and collided with Falis, an infamous and formidable bounty hunter renowned for slaying a dragon. This near-fatal impact triggered an unintended spiritual commutation, swapping their souls into each other's bodies. With Falis now inhabiting Alita's form, she struck a bargain: defending the Forland kingdom in exchange for Alita pledging her body and soul as collateral. Alita, confined within Falis's original body, then adopted the identity of her deceased maid Milano—who sacrificed herself as a decoy during the coup—to aid in governing the realm.

Initially crushed by grief for her father and Milano, and burdened by the duty to protect the kingdom until her elder brother Prince Kaito's return, Alita appeared hesitant and uncertain. Yet her resolve crystallized through ensuing events, notably when boldness surfaced to shield Falis. Discovering Kaito's betrayal and his alliance with the sorceress Cecilia—who sought humanity's destruction using lost technology—Alita risked herself. She posed as her original self to lure Kaito away from an injured Falis, fiercely denouncing him as a disgrace to their bloodline, revealing her newfound courage and iron will. Her evolution into a resilient, decisive figure became clear through active participation in the kingdom's defense and steadfast support for Falis.

Falis, originating from a village annihilated by Cecilia's senseless violence, endured hardships forging her into a ruthless bounty hunter. Wielding the ancestral katana Himetsuru (Crane Princess) and sometimes a dagger, she embodied impulsiveness, resilience, and a thirst for combat. Initially perceiving the princess in her former body as frail and weak-willed, Falis revised her assessment upon witnessing Alita's unwavering determination and bravery. This burgeoning respect cemented Falis's commitment to honor her pledge to protect Forland, adopting the mantle "Murder Princess" after coronation. Her leadership marshaled allies—cyborg bounty hunters Dominikov and Pete Armstrong, and royal butler Jodo—to repel threats from Akamashi and later Cecilia and Kaito. Beneath her rough exterior, Falis displayed unexpected depth of empathy and loyalty, fiercely protecting Alita even after learning dark secrets of the Forland lineage. Their bond deepened into a profound, sister-like connection rooted in mutual sacrifice and guardianship.

The body swap proved irreversible within the narrative. The sole chance for reversal was expended deactivating the apocalyptic device Teoria, requiring the sacrifice of all lost technology—including allies Dominikov and Pete. This outcome permanently bound Falis and Alita to their exchanged roles: Falis continued as Forland's protector-queen, while Alita served as her unwavering supporter in Milano's guise. Their intertwined fates defined a shared legacy of resilience, with Alita's fortified spirit complementing Falis's emergence as a devoted guardian of the kingdom she once viewed merely as a bargain.
