Formally named Ablïarsec Néïc Dubleuscr Bœrh Parhynr Lamhirh, Lafiel bears the title of Viscountess of Paryunu and stands third in succession to the throne of the Humankind Empire of Abh. Born in ICY 935 to Plakia Lexshue and Abriel Dubeusec, she is granddaughter to Empress Abriel Frybac Ramaj. Her unmodified genetic heritage manifests in classic Abh royal traits: blue hair, dark grey eyes, fair skin, and pointed ears, though hers are noted as slightly less pronounced than typical Abriels. This lineage enables her to express profound emotions, including grief witnessed after Hecto-Commander Lexshue's death and during distressing events involving Jinto Linn. Demonstrating exceptional aptitude early, Lafiel entered military training at age 13. Her rigorous curriculum encompassed jousting, small arms, and vessel command, culminating in her assignment to escort the culturally unfamiliar Abh nobleman Jinto Linn aboard the *Gosroth*. This mission forged their enduring partnership. Facing United Mankind forces, Lafiel reluctantly evacuated with Jinto under orders, navigating behind enemy lines and confronting adversaries like Baron Febdash Klowal. Her tactical ingenuity emerged when she secured her first combat kill by defeating Klowal via depressurizing his fighter craft through anti-matter fuel dumping. Lafiel's personality blends assertiveness with deep duty. She favors aggressive solutions, often tempered by Jinto's diplomatic influence. Despite her royal status, she rejects excessive deference, valuing merit over lineage—a preference rooted in Jinto's initial unawareness of her title, allowing their authentic friendship. Her leadership matured during operations like Phantom Flame, where she embraced responsibility for allied crews' lives. This growth continued commanding the assault ship *Basroil* defending the Laptic Gate and serving as an ambassador on a prison planet, where Jinto's kidnapping tested her resolve. Her relationship with Jinto remains central. In *Banner of the Stars III*, she accompanies him to his homeworld in the Hyde Star System, defying typical Abh disinterest in planetary environments. There, she supports his negotiations for Martine's surrender to the Empire—a process demanding his permanent exile. This mission underscores her loyalty as she prioritizes his safety and objectives despite personal reservations about gravity-bound worlds. Later events see Lafiel ascend to Crown Princess following the Hania Federation's surprise attack that destroyed the imperial capital Lakfakalle. After Empress Ramaj perished in the assault, Lafiel assumed her new role under Emperor Dusanyu, bearing the symbolic weight of the Empire's future while continuing military service. Her backstory expands in the OVA *Passage of the Stars – Birth*, depicting her parents discovering a derelict ship containing bio-roid remains during their honeymoon. This encounter inspired her name, signifying "gem" and "source of life," reflecting her parents' view of her as a symbol of love and resilience.
