Leivinia Birdway

She is a 12-year-old girl with short blonde hair, blue eyes and a petite figure who wears a white dress, with black stockings. It is referred to as chic, and her dress gave out a grand piano-like impression. Still a child, her bosom has yet to develop, much to her chagrin. She's 140cm tall, Her younger sister is called Patricia Birdway.

About her personality Leivinia is a capable leader, able to lead an entire cabal on her own full of adults. To Leivinia everything is about the cabal, according to Mark Space, to Leivinia, her subordinates are nothing more than small gears within a large plan, and their survival is not a necessary part of that plan's success. She would also manipulate people she thinks would be useful, like Kamijou Touma and the rest of his ilk during Hawaii. She exudes confidence, showing no fear when Touma had a drill on her head, knowing that she could escape it if she wished.

However, despite all her haughtiness, there is more to Leivinia than a powerful and confident leader of a magic cabal. She is still a child despite all of this, arguing with someone like Fremea Seivelun, who thinks Santa Claus exists, sleeps with a nightlight on, as well as despises being reminded that her bosoms is underdeveloped. She doesn't like panties with a large rabbit on them or anything spicy. For all her manipulativeness, she can dish it out but she herself cannot take it. When she discovers that Touma himself has manipulated events into his favor, she becomes strung up on the subject, and becomes easily irritated when the subject is brought up. According to Touma's observations, Leivinia is a person who loves effort and does not turn away from hard work, charming people who support her large organization with something other than her words. She is also fond and protective of her younger sister, as shown when she orders Mark Space to go and rescue her, despite not wanting to involve herself with Exit of the Evening Dusk's operations.

About her background She was the eldest between her and Patricia Birdway. She is a talented magician who has received various proposals from many organizations to join but flatly rejected them all. It is unknown how she came to be the boss of the Dawn-colored Sunlight, but her magic talents most likely stem from her hard work.

In the cabal, she investigates the leaders and charismatic people of various organizations in order to search out the best course wit.

As a leader of Golden-style she should be able to create a temple following set laws and the quality, element, and directionality of the power being used is decided on. Once that is done, Hebrew letters are used to provide imaginative power and a temporary guardian that possesses Telesma is prepared.

She seems to personally cast aside such processes for her magic. However, Leivinia's magic is apparently spontaneous or does not rely on the strict techniques of spells or ceremonies, and instead she uses shortened and simplified techniques. However, these are all calculated actions, where Leivinia Birdway accurately repeats the proper technique, arranged to cover her weaknesses and limits. Using precise movements that are actually magic symbols and repeatedly training, Leivinia can boost her magic through those movements.

Her magic name is Regnum771 which means "kingdom" in Latin. With this, it seems to fit in quite well with the philosophy of her cabal, which is to analyze the leaders and charismatic people in order to search out the best course with which to seize the core of world.

She can summon Gungnir: Drawing on the knowledge of Index's grimoires, Leivinia was able to construct a version of Gungnir fine-tuned for human use, lacking many of the powers that Gungnir possesses. Referred to as an Imitation Divine Technique, it is only capable of recreating a high-quality phenomenon regarding Gungnir's use as a throwing lance. In order to recreate this phenomenon, she has to draw out information on it from the minds of those know it by continually receiving knowledge from Index's grimoires despite the danger they pose - interrupting the connection will destroy the lance. If it successfully reproduced the phenomenon of the throwing lance, the world (the world refers to universe) would likely be destroyed, as with the real Gungnir.

She can also summon a Steel Blade: Leivinia summons a steel blade that rotates a like a giant electric fan to attack the opponent.

She can also summon a Electric attack: Leivinia summons an electric attack that bounces like a pinball in an area.

She also use Flintlock pistol : Disliking modern guns from the science side, Leivinia prefers to use a Flintlock pistol, apparently liking its contours, and the time she spends loading the bullet.
