Lucia

Lucia (ルチア) is a member of the Agnese Forces and part of the supporting cast of Toaru Majutsu no Index.

Appearance
Lucia is a tall girl with short blond hair and blue eyes. Her hair is usually concealed under a black coif, leaving a lock of hair on each side of her face exposed.

She usually wears the black scapular of the Roman Catholic Church which has a white collar and sleeves and a dark gray cross detail. Like her leader Agnese Sanctis. she detaches the lower part of her scapular, exposing much of her legs. Lucia also wears black stockings secured in place by a garterbelt, and brown loafers.

Personality
Between her and Angelene, who is usually seen as a pair, Lucia is more serious, and she is usually the one who would scold her partner Angelene whenever she makes mistakes in her work.

She is also revealed to be very hateful of non-believers, as realized by Kamijou Touma, who is ruthlessly attacked by Lucia when he touches her shoulder.

Orsola Aquinas Rescue Arc
Lucia, along with Angelene, and the rest of the nuns under Agnese's command are sent from Rome to retrieve Orsola Aquinas. After their fight with the Amakusa Catholics, Lucia and Angelene are ordered to take Saiji in, but is interrupted by Touma who harmlessly touches her shoulder. Lucia goes berserk as a result of this, and tries to eliminate him by using her ability. Before she has the chance, she's further interrupted by Index's Spell Intercept and, upon hearing the retreat signal by Agnese, retreats.

She later returns to defend the Church of Orsola against an attack by Touma, Stiyl Magnus and the Amakusa Catholics. Lucia emerges after witnessing her comrades succumbing to the effects of Sheol Fear, and using a special kind of command spell, places the group of nuns under her command into an "override" mode, allowing them to pierce their eardrums without any display of pain.

English Civil War Arc
When Lucia, Angelene and Agnese overheard one of Amakusa group's conversation of who will be able to steal Touma's heart out of Kanzaki and Itsuwa, Agnese and Lucia discussed among themselves who in the Agnese Forces can match the two from Amakusa in womanly charms, and decided Lucia is capable with her bust size and attempted to get Lucia into an imp cosplay, which Lucia refused.

Abilities
Lucia uses a large carriage wheel as focus of her magic; the wheel based on the legend of Saint Catherine of Alexandria. The wheel's spokes are meant to be shattered like shrapnel, and, interestingly, regenerates itself by recovering the shrapnel.

In later events, she is revealed to be experienced in Wind-element magic, which is denoted by the yellow colors in her new attire when she travels to Chioggia.
