"It's alright! I will absolutely protect Mai! Without fail!!"
Kajun Faycott (カジュン=ファイコット) is a scientist for Sector Seven and a close friend of Mai Natsume. She is one of Kokonoe's assistants, and is both a spy and researcher. She created the Legacy Weapon - Gallia Sphyras: Outseal. Kajun has an insatiable thirst for knowledge and an unbreakable bond with Mai.
A young woman with fair skin and long lavender hair that comes to her lower back; Kajun's bangs end just above her lavender eyes. Kajun is always seen wearing a black headband with a black butterfly piece attached to it. Her usual outfit consists of a short purple dress that shows her cleavage and stops just above her thighs. Over this she wears a stylized white coat with black hems, purple cuffs, and a butterfly motif on its left side. Kajun's look is finished with black tights, purple boots, and a loose black belt around her coated waist.
When posing as a student in the Military Academy, Kajun wore its uniform, although she customised it to her own tastes. She wore a short skirt with black tights and black high heels that had butterfly wings on the back of them. Her uniform's jacket was more similar to a long coat that came down to her knees; the black belt holding the coat together was constantly left open, and her headband had a white and lavender colored pattern.
The Golden Angel turned into a purple torpedo swimsuit for Kajun. She once infiltrated the Novus Orbis Librarium, taking a typical Ars Magi "Jolting Sapphire" uniform, and wore both its poncho and beret.
Absolutely obsessed with research and the pursuit of knowledge. Kajun has many quirks in her personality, but remains affable to everyone she comes across. To this end, she works hard under Kokonoe and Sector Seven, and will do nearly anything to ensure that she does not fail in her missions. Even though she is a dedicated scientist and researcher, Kajun has a good sense of humor and can be startled easily by things that she does not expect - however, she is prepared for nearly every situation, making this a rare occasion.
Kajun has a deep affection for Mai, and will go to any means to protect her. The two are close enough to fall asleep together, and Kajun herself even developed the Outseal with Mai in mind. Their relationship appears platonic as their bond is that close.
Always carrying an air of mystery around her, Kajun also flaunts her intelligence every now and again, using her vast amount of general knowledge to answer just about any question that comes her way. In front of one of her superiors, such as Kokonoe, she flounders and has been known to excessively apologize for making even tiny mistakes. She constantly maintains a cute attitude to those around her, making her occupation as a spy for Sector Seven difficult to deduce.
Powers and Abilities
Despite being a member of Sector Seven, Kajun excels in Ars Magus, and is well versed in both its application and theory. It is to this end that she was able to pose as a Military Academy student for so long and not arouse suspicion. She is also a remarkable spy who was able to discreetly hunt for the Azure Grimoire with nobody discovering her identity, even when she worked closely with teacher Ellen Nelson and student council president Jin Kisaragi. After her stint in the Academy, Kajun has seemingly taken a less on-hands approach, and communicates with Mai on missions by giving her directions.
However, Kajun is not someone who cannot fight on their own. In combat, she uses various chemicals that are held to her side in vials. Holding them between her fingertips, she can throw them at opponents for deadly results and can concoct them for various effects, such as creating a large explosion or setting things alight.
As a scientist, Kajun is a revolutionary who created a Legacy Weapon, a weapon on par with the Nox Nyctores. Keenly aware of her surroundings, she is able to deduce anything from a glance, making her a fierce opponent when paired with someone more physically capable. This is where Kajun's weakness starts to show, however, as she only has so many chemicals at her disposal, and has been noted to not be as physically strong as Makoto Nanaya or even Mai.
