Eve of the Festival
According to Thor, Ollerus has gathered together a gaggle of powerful magicians for the purpose of opposing GREMLIN in Academy City. Among the people he mentions is Leivinia. This is later proven correctly, as after the fiasco of Fraulein Kreutune escaping the Windowless Building, Touma and Thor, correctly predict that Ollerus' group will require a scout. Here, Leivinia first appears tailing Marian Slingeneyer after she falls for Touma and Thor's trap, and in turn, is tailed by Touma. Part of Touma and Thor's plans require the scout, Leivinia, to believe that he has joined up with GREMLIN, as so to make GREMLIN think that Academy City and Ollerus are attacking them, and Ollerus think that Academy City and GREMLIN are attacking his group, allowing them to buy time to safeguard Fraulein.

While following Leivinia, Touma grabs a power drill and aims it at Leivinia's skull. With arms spread out, Leivinia is completely nonchalant regarding Touma's threats. Touma tells Leivinia not to move as he has the advantage, but Leivinia asks if he really expects that he can kill her with the drill. Leivinia then states that she never expected him to act in behalf of GREMLIN. Touma tells Leivinia that he has no idea if what he is doing is right or wrong, but says that it is at least, it is due to him thinking through things for himself. Leivinia says that he might've been tricked into doing it, to which Touma replies that she is the one who specializes in doing that, to which Leivinia falls into silence.

Leivinia is completely ignored during Touma's tirade regarding the hell that happened in Baggage City, her role in keeping damage to a minimum, and the fact that despite all she did, he still deemed it as something that is not the best answer, as Kihara Kagun died, bringing Kumokawa Maria to tears, and that she still used Baggage City to her own end. Touma then asks her how he is supposed to unconditionally trust someone who did all that. For but a moment, there was no reply from Leivinia. When she speaks, however, she coldly tells him to move the "toy" he is carrying out of her way, and that he has created a situation that he no longer has grounds that will not stop her from killing him, as he threw it away before her now.

Just then, as the tension becomes thicker, Anti-Skill arrives, and sees Touma's threatening Leivinia. One of them however, accidentally takes out his rifle and starts shooting at Touma, much to the horror of everyone present. Leivinia cradles the bloodied Touma in her arms, and tries her best to use first aid on him, not allowing the Anti-Skill to interfere anymore. As she begins to leave, she tells Anti-Skill of Touma's condition. With her bloodied clothes and hand, that she is unable to wipe since she used her handkerchief for Touma's first aid. It is shown that she has taken Touma's bait, the student handbook he had where he wrote Marian Slingeneyer's name. She calls her comrades, and tells them that Touma was won over by GREMLIN. She reports to them on how Touma is working with Marian, and the details regarding her name in the student handbook. She also tells the person on the other side of the phone that GREMLIN is based in School District 12, from the notes on Touma's handbook, and says that she wants them to crush GREMLIN using a surprise attack as it is the perfect chance to do so.

Touma however, barely conscious, overhears this as he is carried out by the EMTs, satisfied that she has fallen for the bait, and that he used the unforseen arrival of Anti-Skill as the means to convice Leivinia.

Abilities
As a leader of Golden-style her magic creates 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. Based on the concept of "Symbolic Weapon" suits of wands, cups, swords, and coins she can create symbolic weapons of fire, water, wind, and earth respectively.
 * Summon Explosion (召喚爆撃), using accurate intuition and measurements made by eye rather than relying on accurate theories and calculations, she is able to accurately use the right amount of Telesma to create a series of dome-shaped explosion attacks.
 * Tarot (Major arcana), Birdway is able to use major arcana tarot cards for different effects, so far she has use "Hanged Man" to transfer for one time all damage done to herself to the card.

Magic items
The Wand of Swords and Cups is her wooden wand that opens up like a flower (continuing with Haimura's theme of plant-like wands). The true extent of its power is as of yet unknown, however, she uses it during her mimicry of dawn to aid against Cendrillon's magic. It can also transform into a cup for reasons unknown. It also works even if it is broken. It may be related to the Minor Arcana, which employs swords and cups in its cards.

Firearms In accord to her she can't love recent guns from science side but the old designs like the Flintlock, her weapon of choice, because she can enjoy the time she spends loading the bullet.

Design evolution
Leivinia's design remains the same since her appearance in the sidestory. Despite being twins with Patricia, Leivinia has a stark difference of design from Patricia. Haimura also designed Leivinia wearing high-heels to mark her as the elder sister.
