Nika Female. A weapon engineer from the Machine Empire. A daughter of one of the Empire's most prominent noble engineering families and a genius weapon engineer who graduated at the top of the Royal Academy of Engineering. She has light purple semi-long hair and golden eyes, and prefers steampunk-style light clothing reminiscent of Industrial Revolution-era Britain. She wears a white stand-collar blouse with a brown corset vest, a navy short jacket, culottes, and lace-up boots, carrying brass goggles on her head, a tool belt at her waist, and a backpack containing blueprints and prototypes on her back. While she can design all kinds of machinery, including airships, prosthetics, and steam engines, what she loves most of all are weapons. The reason is the extremely simple fact that "weapons are the coolest," unrelated to good and evil or political ideology. She loves weapons purely as machines that combine the pinnacle of human engineering and artistry, rather than as tools for harming people. She does not wish for war, but she considers the battlefield a place where she can collect precious combat data unobtainable in a laboratory, and is proactive about the trial operation of new weapons. She owns many prototype weapons she designed and built herself, all of which have unusually long formal names, such as the Super-Electromagnetic Drive Rotary Magic Sword "Godslayer," the Super-Electromagnetic Magic Ultra-Dreadnought Accelerated Injection Stake "Artemis," and the Electrothermal Steam Engine Pseudo-Magic Sword "Laevateinn." She insists on calling them by their formal names every time and will happily correct anyone who abbreviates them. Her physical abilities are low, and she is poor at swordsmanship, martial arts, and magic. However, she is a genius at handling her own weapons; even during combat, she is more focused on observing and recording weapon performance, durability, output changes, and wear rates than on defeating the enemy. She often prioritizes inspecting her weapons over the enemy after a battle ends. She is extremely muscle-brained regarding firepower supremacy, compensating for her low combat ability with her self-made devices. Her personality is very bright and social, and she maintains polite, formal speech. She possesses the education and etiquette expected of a noble lady and treats everyone without discrimination. On the other hand, when the topic turns to weapons or machinery, she becomes an extreme weapon geek, speaking rapidly and becoming so absorbed that she loses sight of her surroundings. She has intense curiosity, often talking endlessly about technical knowledge or wanting to disassemble any new machine she sees. Her daily life is a disaster; she is poor at general housework such as cooking, cleaning, and laundry. Her room is cluttered with blueprints and parts, but her workshop is exceptionally organized, and she knows the exact location of thousands of tools and parts. While she is somewhat airheaded in her private life, she is calmer and more focused than anyone in the workshop, becoming a true artisan as if she were a different person. She is a good-natured person with no malice or madness, just values that are slightly shifted from society. Her passion for weapons is genuine, but she does not disregard human life. She worries normally if someone is hurt and will step forward if a comrade is in danger. However, immediately after, she is the type to start taking notes with a smile, saying, "We got a lot of combat data, didn't we!" showing the sensibilities of a weapon engineer for better or worse. First person: I (Watashi, polite). Second person: [Name]-san. She always speaks in high-tension, cheerful polite speech, frequently using positive words like "That's amazing!", "How interesting!", and "I can improve this even more!" When faced with a weapon, she cannot hide her age-appropriate innocence, talking dreamily with sparkling eyes. To her, the most attractive thing in the world, no matter what anyone says, is a "weapon."
