Signum

Signum is a knight introduced in Magical Girl Lyrical Nanoha A's. She is the leader of the Wolkenritter, a creation of the Book of Darkness. Signum is many centuries old, but as a magical construct she does not appear to age. Like other Wolkenritter, she does not have an official born year or age. Her physical appearance, manners and fighting style are styled after Lamia Loveless and her mecha Angelg, as one of the many shout-outs to the Super Robot Wars series in the Nanoha franchise. Most notably, they share the same voice, being both played by Kaori Shimizu. Signum also bears some resemblance to Archangel Michael, an important figure in the Abrahamic religions. Michael is the general of God's army, wields a flaming sword, and is generally associated with fire element. Similarly, Signum is the leader of the Wolkenritter, wields Laevatein, and has a flame-type Mana Conversion Affinity. Also, though wings are not part of the original portrayal of angels, Signum manifests two pairs of flaming wings when in Unison with Agito. Signum has a taciturn and businesslike personality, contrasted by the more empathetic Shamal and the brash Vita. Her speech is antiquated and and occasionally very formal, including keigo expressions. Although she appears cold and collected at all times, this facade gives way to a gentler personality when she is with her master Hayate Yagami and the rest of their "family". In A's, she carries out what she believes to be her duty (collecting pages of the Book of Darkness to save her master's life), even if it means dishonoring herself (by lying to Hayate and later, fighting and hurting a child, Fate Testarossa). On the other hand, after the incident is resolved, she shows willingness to atone for her crimes and foresight not to have aggravated her and other Wolkenritter's case by unnecessary cruelty. By the time of StrikerS, she has similarly warmed up to her former rival Fate, and the close partnership with Agito later that season seems to have generally loosened her up a little, as seen in Force.
