Alisa Takakura, 21, possesses striking white hair and violet eyes. Her past involved membership in a criminal organization alongside her lover, Jean Luc Skinner, participating in illicit activities like a bank heist. This operation ended catastrophically, inflicting severe injuries that necessitated extensive cybernetic reconstruction, including neural link technology. Believing Jean Luc perished, Alisa became tormented by recurring nightmares of these events.

Seeking refuge, she joined the Angel Arms Company, a private security force in Bayside City. There, she piloted a specialized black Landmate combat suit designated "Dolche." Alisa maintained a solitary and distant demeanor within the team, often isolating herself. This behavior, coupled with her undisclosed criminal history, fueled distrust among teammates who perceived her as a potential liability on missions. Founder Takako Houraiji knew Alisa's past but kept it confidential, intensifying the team's suspicion.

Her internal conflict erupted upon discovering Jean Luc alive, sent to assassinate Angel Arms' protectee, arms dealer Ali Jaheeve Hassan. This revelation forced Alisa to confront her loyalties: remain with her new team or return to her former life with Jean Luc. It deepened her emotional turmoil as she wrestled with the moral weight of her past actions and current duties. Her combat prowess and cybernetic enhancements made her a formidable asset, though recklessness and self-endangering tendencies sometimes emerged during operations.

The climax of her arc centered on this stark choice between embracing her Angel Arms role or rejoining Jean Luc. This decision was complicated by her unresolved trauma and the realization that her former lover now posed a direct threat to her present existence. Her journey highlighted themes of redemption and the struggle to reconcile a violent past with present possibilities for change.
