Description
Signum, a centuries-old knight forged by the Book of Darkness, commands the Wolkenritter as their general while serving Hayate Yagami. Bearing the titles “Knight of the Sword” and “General of the Raging Fire,” she wields the chain-link sword Laevatein, adaptable into a whip (Schlangenform) or bow (Bogenform) to launch attacks like Sturm Falken, a high-speed explosive projectile. Her combat style, inspired by Lamia Loveless of *Super Robot Wars*, pairs a purple mana affinity with fire-elemental magic, including the flame typhoon Hiryū Issen and Karyū Issen, which obliterated over 50 combat drones alongside her Unison Device, Agito.
Initially stoic and duty-driven, Signum prioritized filling the Book of Darkness to save Hayate from fatal paralysis, even deceiving her and opposing the Time-Space Administration Bureau. She clashed repeatedly with rival Fate Testarossa, shattering Fate’s device Bardiche in combat. Despite her ruthless efficiency, Signum minimized collateral damage by incapacitating targets non-lethally during Linker Core thefts, intending to surrender post-mission for leniency.
After the Book’s completion nearly killed Hayate, Signum and the Wolkenritter were resurrected through Reinforce’s sacrifice. Post-crisis, she joined the Time-Space Administration Bureau as a Special Investigator Assistant, rising to leadership roles in the Midchilda Capital Air Force and Riot Force 6. Her interactions with Hayate and partnership with Agito—forged after defeating Zest Grangeitz—softened her demeanor, enabling her to manifest flaming wings in unison and express previously guarded warmth.
In *INNOCENT*’s alternate universe, Signum appears as a kendo-coaching university student within the Yagami household, managing a bookstore and evading chores. *Force* depicts her wielding the Gladiator device, mentoring trainees like Erio Mondial despite her preference for direct combat. Manga interludes showcase her tactical expertise in coordinating Relic missions and inconclusive mock battles.
Signum retains archaic, formal speech, contrasting her growing emotional openness. Unwavering loyalty to Hayate anchors her actions across timelines, from atoning for past deeds to protecting Lutecia Alpino per Zest’s final wish. Her design echoes Archangel Michael’s fiery symbolism and leadership motifs, while her German-speaking device reflects the Wolkenritter’s thematic origins.
