Lucia

Lucia (ルチア) is a member of the Anieze Forces. She is tall, slightly long, blonde hair and blue eyes. She appears to have a serious nature.

Orsola Aquinas and the Book of Law Arc
Lucia, along with Angelene, and the rest of her teammates are sent from Rome to capture 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 and goes berserk, trying to kill him. Before she has the chance she's further interrupted by Index and that she is called back by her team.

When Lucia, Angelene and Anieze overheard one of Amakusa group's conversation of who will be able to steal Touma's heart out of Kanzaki and Itsuwa, Anieze and Lucia discussed among themselves who in the Anieze 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 Catherine of Alexandria. The wheel's spokes are meant to be shattered like shrapnel, and, interestingly, regenerates itself by recovering the shrapnel.
