Formally identified as Fia Arcana, the character known as "Fori" carries alternative names including Faurink Maya, Faulink Meijer the Plasmatizer, Faury, and Folli. She originates as the daughter of a master practitioner of Sui Rem, a discipline employing magical talismans in combat. Following her father's death, Sui Rem tradition compels disciples to cast off their names until achieving vengeance, leading her to adopt Faulink Maya.

Initially harboring resentment towards Elle Ragu, Fia Arcana's feelings escalate to vengeance upon receiving false information implicating Elle in her father's murder. She confronts Elle in a duel within a mine, resulting in the structure's collapse. When trapped beneath debris, Elle unexpectedly rescues her. This act initiates a shift in her perception, prompting doubts about Elle's culpability.

Subsequent investigation reveals Louie Francil, another disciple of her father, as the true killer. Louie orchestrated the conflict intending for Fia Arcana and Elle to eliminate each other, securing sole claim to their master's legacy and title. This truth, uncovered during a confrontation where Gau Ban defeats Louie, resolves the enmity between Fia Arcana and Elle. Their relationship evolves into a sisterly bond. Fia Arcana assumes a protective and morally guiding role for Elle, often functioning as her conscience.

Manga continuity details her personal history, revealing a marriage to Woaks Porelo in Juliannes four years prior to the main events, when she was fifteen. She departed from this marriage specifically to pursue vengeance for her father's death. Her culinary skills are notably poor. Professionally, she earns the moniker "The Plasmatizer" and masters formidable talisman-based magic, specializing in summoning and spell-casting techniques intrinsic to Sui Rem. Within the group dynamic, she provides strategic and intellectual counterbalance to Elle's physical prowess.
