Lancis, a member of the magic cabal New Light, initially supported Princess Carissa’s coup in the United Kingdom before opposing her destructive agenda. Sporting short brown hair held by a headband, she dons a lacrosse-inspired uniform of a shirt, miniskirt, and spats, augmenting her fingers with dragon talons during magical tasks. Notably shorter than Misaka Mikoto, she self-deprecatingly references her chest size in comparisons. Her lethargic demeanor belies sharp situational awareness—she often naps through routine duties at Maguro Hiroi yet displays pragmatic resourcefulness, maneuvering crowds undetected or swapping outfits publicly to evade notice. Driven by unwavering patriotism, she prioritizes the UK’s survival, even if it means defying leaders or harming others. Tasked by Carissa to unearth the Curtana Original, a magical artifact pivotal to reshaping UK politics, Lancis operated from Edinburgh under the Cabal Reserve Army’s guise. As the artifact’s "keeper" during the British Royal Family Arc, she transported it in a case 30 kilometers north of London, relaying messages via spiritual items despite a persistent tickling from magic purification—a sensation doubling as an alarm for nearby spellcasting. Post-Elizard’s distribution of Curtana’s power, she contributed to New Light’s decisions in the British Halloween event. Later, during the Homecoming Arc, she dismissed Lessar’s teasing proposals to seduce Kamijou Touma after intercepting Anglican intel about his return. In *Railgun SS2*, she aided Mikoto Misaka at Maguro Hiroi, supplying swimsuits and escape routes through a leisure pool, unperturbed by Mikoto’s flustered reactions or her own drowsiness mid-conversation. Her magic draws from Norse myths, wielding the Steel Glove—a polearm shaped like a four-digit hand tied to Thor’s legends—to amplify strength, unleash destructive strikes, and manipulate intangible forces. She casts wide-area spells to bolster allies like Bayloupe, balancing the disruptive tickling during magic use with its utility in detecting nearby threats. Serving as New Light’s logistical anchor, Lancis employs the Skíðblaðnir case to shuttle the Curtana between allies. Her tolerance of Lessar’s antics and collaborations with Floris and Bayloupe underscore her adaptability and loyalty. Though seldom on the frontlines, her strategic coordination and magical expertise remain vital to the cabal’s objectives.
