Lucretia

Lucretia (ルクレティア, Rukuretia) is a pale-haired girl who is a member of the Irregulars. She possesses a Geass ability known as "The Land," which accurately maps three-dimensional terrain within a given range. When her ability is active, a Geass sigil appears upon her forehead. She is typically partnered with Sancia, whose tracking Geass ability complements her own. After the final battle, she and her teammates help around the Ashford Academy that has been transformed into a temporary refugee camp.

Personality
In the Manga, she is portrayed as a quiet, meek girl, and a sharp contrast with her teammate and Sister Dalque. She is seen as a voice of reason for the Irregulars and usually despises violence but realize the futility of her wish when confronted with the stark reality of working as a slave for Britannia. During the attempted capture of Alice, she is willing to refuse a direct order from her superior to protect her sister.

Abilities
Compared to her other Sisters Lucretia is the only one without a fighting role in the team instead she uses her Geass to scan the perimeter and help her sisters with valuable intel about the enemy. The results of her perceptions are instantly submitted to her Knightmare Frame via a cockpit neuroimaging device and collated with GPS data before being distributed to her team for tactical purposes. She is often seen with Sancia since their Geass complement each other quite perfectly, acting as the team tactician while Sancia executing enemy from safe distances, they can virtually defeat any foe.

Knightmare
She pilots her own Variant of GX 01 Knightmare Frame until it is destroyed by Cardinal Rolo vi Britannia during the subsequent hunt for Alice.
