Paife teaches health at Millie's school in Emporium, openly avoids men, and carries a firearm. Her path crosses with the main group when she accompanies Honoka on missions into the desert wasteland, revealing an apparent romantic or sexual interest in Honoka during their travels. On these joint operations, Paife senses and manipulates chi like Honoka, enabling her effective combat participation. She joins Honoka's team for assignments, including investigating stampeding sand dragons that lead toward the space-time distortion Gravestone. Functioning as a capable fighter and tactical partner alongside Honoka, Iks, and Bogie, her combat skills and chi manipulation establish her as a formidable presence.

Despite her outward boldness, Paife struggles to articulate her deeper feelings for Honoka, harboring unspoken emotions. Near the story's conclusion, she helps Iks understand his romantic feelings for Honoka. Afterward, she remarks the experience felt "like a wife helping her husband find his mistress," underscoring her complex emotional position. Her relationship with Honoka remains defined by this unresolved tension.
