Lukshana, occasionally spelled Lukshana in English translations, inhabits elven territory as an elf with distinctive pointed ears, long light blonde hair featuring bangs, a fair complexion, and bright sky-blue eyes. She displays insecurity about her average bust size, particularly when comparing herself to Tiffania.

Working as a human researcher, Lukshana expresses intense fascination with human culture despite habitually labeling humans as "savages." She conducts studies from a secluded desert oasis within elven lands, where she temporarily detains Saito and Tiffania for observation while the Elvish Elders deliberate their fate. Her research highlights key differences between elves and humans, especially in relationship dynamics observed between Tiffania and Saito.

Personality-wise, Lukshana exhibits curiosity, friendliness, and adventurousness. She assists Tiffania and Saito in fleeing the Elven Council, returning Derflinger to Saito during their escape. When pursued by elven guards, she effectively employs magic under stress to shield the escapees from sleeping mist. Her adventurous spirit surfaces in her enthusiasm for visiting human settlements and exploring new environments like castles.

Lukshana maintains a romantic outlook, evidenced by tears during a scene of mutual understanding involving Louise and Saito's separation. Engaged to an elf named Ari, she frequently threatens to cancel their wedding to coerce his support for her plans. Ari remarks that she habitually involves him in "idiotic plans," indicating her impulsive tendencies. She shares family ties with an uncle, Bidashal, suggesting inherited research inclinations.
