Lucia

Lucia (ルチア) is one of the more prominent members 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. She lost her hate for non believers and particularly for people outside the Roman Catholic Church was when the higher ups from the Roman Church betrayed Agnese and tried to use her as a scape goat and then a sacrifice for their own means.

As a person she is both loyal and strict torwards those she holds close, she greatly respects sister Agnese, having more loyalty to her than to the Roman Catholic Church. Within the Agnese forces she has been stated as the only one that might be able to fight in equal terms with Kaori Kanzaki or Sherry Cromwell if they all happen to don bold cosplaying costumes (and unusual recurring theme in the Necessarius dorms).

 * Main article: 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 commands the nuns to pierce their ears with their pens as so to block out Sheol Fear.

After the events of the arc, Lucia is taken into custody by the Roman Catholic Church and is later used as a scapegoat for them like the rest of the Agnese Forces.

 * Main article: La Regina del Mare Adriatico Arc

As punishment for the events in the Orsola Aquinas incident, she and the Agnese Forces are taken to the Queen's Fleet of The Queen of the Adriatic Sea as a labor force. Here, she wears the Forbidden colored robe as so she is unable to use magic, as well as to prevent her escape. However, Lucia along with Angelene are able to modify the robes enough to be used as a tool for a magic spell, which they used to escape. They are however later captured again after the second effect of the robes take effect.

Kamijou Toum and Orsola Aquinas later rescue them after being asked by Agnese Sanctis. Though she is suspcious at first, she later yields after Orsola Aquinas convinces her. They later show Touma and Orsola how they escaped, and are later angered by the fact that Touma and Orsola allowed Agnese to go to the flagship, the Queen of the Adriatic Sea, as she would be used as a sacrfice for a spell, the Rosary of the Appointed Time.

She later joins the Amakusa to stop the Queen of the Adriatic Sea from activating and rescue Agnese Sanctis. She stays behind to occupy her former comrades from the Agnese Forces, after Angelene gets injured during the battle.

After the destruction of the fleet ship, Lucia and Angelene join the Anglican Church.

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 Angelene 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. As explained by Idol Theory, the wheel was used as an execution tool for Saints, though when the wheel was touched by a Saint which in this case was St. Catherine of Alexandria, it would explode and harm the executors and everybody else who watched the execution instead. The legend of the wheel of that killed those who watched St. Catherine's execution and her executors, is applied to Lucia's wheel where it would harm the guilty, which in this case the person that Lucia deems guilty.

The wheel's spokes are meant to be shattered like shrapnel and regenerates itself by recovering the shrapnel.

Other abilities
Along with Angelene, she is able to modify the Forbidden colored robe she was forced to wear and use it as a tool for a magic spell, along them to escape the ice ship, during their captivity in the Queen's Fleet.
