Description
Tiffania Westwood, a half-elf born to Archduke de Albion and the elf Shajar, carries royal Albion lineage and elven heritage. This mixed ancestry exposes her to prejudice, prompting her to conceal pointed ears under a hat. After her mother's death during a childhood trauma that killed her family, she lives secluded in Albion's Westwood Forest within an isolated cottage.

She has long blonde hair, light blue eyes, and notably large breasts that draw frequent attention from characters like Guiche, Malicorne, and Osmond, sparking jealousy in Louise and Siesta. Early naivete about social norms and her body leads her to ask Saito Hiraga to verify her breasts' authenticity, unaware of implications.

Her life shifts upon rescuing Saito in Albion's forest using a magical healing ring inherited from her mother; the ring depletes after healing him and was her sole access to elven magic. Saito dubs her "the big-breasted fairy." Under Queen Henrietta's protection—who recognizes her royal lineage and kinship—she relocates to Tristain Academy of Magic but faces ostracization as a half-elf. Saito's intervention aids her gradual acceptance, especially after noble Beatrice falsely accuses her of heresy and subjects her to a boiling-water trial. Saito defends her, Louise intervenes explosively, and Tiffania forgives Beatrice, offering friendship that cements her social integration.

Later confirmed as Albion's Void mage with initially latent abilities, her early magic includes a memory-wiping spell from Joseph de Gallia's music box, used reluctantly as it deepens her alienation. The Pope of Romalia formally acknowledges her Void affinity in season four, and Henrietta grants her Albion's royal ring, affirming her royal status. Under Colbert's instruction, she performs the familiar summoning ritual, with Saito emerging as her familiar. This dual summoning confirms Saito's unique role for two Void users, Louise and Tiffania. Her ambiguous feelings for Saito clarify into romantic affection.

She evolves from naivety to perceptiveness and cynicism, particularly toward others' suffering and motivations. Though adept at recognizing lecherous intentions, she remains unbothered by Saito's attention due to affection. Her feelings manifest as deep, trusting friendship rooted in his being the first peer to accept her elven heritage without fear. She navigates Louise's tsundere tendencies; jealousy arises when Saito pledges to protect her out of gratitude, but no significant rivalry develops.

In Volume 19, elves targeting Saito kidnap her upon discovering her Void abilities. They administer a mind-altering drug, mirroring Tabitha's mother's treatment. Rescued by a sympathetic elf, she aids Saito in combat against the elf's fiancé. Following Derflinger's advice, she exposes herself to revive near-unconscious Saito, initially unaware of consequences and later embarrassed.

Her role expands at the academy and in broader narratives as she reconciles dual heritage, masters Void magic, and strengthens bonds with Saito, Louise, and Tristain's royal family.
