Leska, alias Café au Lait, serves as the self-declared secretary to antagonist Don Harumage and combat partner to Da Cider, wielding feather darts with precision. Her early demeanor blends theatrical eccentricity and calculated vanity, prioritizing bold fashion choices and leveraging her allure to manipulate adversaries. A climactic twist exposes her suppressed identity as Caféaulae Arara—the exiled first princess of the Arara Kingdom and elder sister to Milk and Cocoa. Freed from Harumage’s brainwashing, her physical traits transform: her blue mesh attire transitions to vibrant orange, and her ears elongate into an elf-like silhouette mirroring her siblings.

Renouncing her antagonistic role, she allies with the protagonists as a Holy Sister, uniting with Milk and Cocoa in synchronized energy assaults. These collaborations, though temporarily petrifying her during critical battles against existential threats, cement her redemption. Post-reformation, her dynamic with Da Cider evolves from pragmatic partnership to overt romance, highlighted by a climactic kiss in the series finale. While her flamboyant style and strategic charm remain intact, her objectives realign with the protagonists’ mission.

Her nomenclature ties to the series’ drink-themed lexicon: “Lesqua” abbreviates “Lemon Squash,” and “Caféaulae” directly echoes “Café au lait,” reinforcing her narrative ties to both royalty and the show’s whimsical motifs.
