Tsubasa Kawana

Tsubasa Kawana is a friendly but ever-so-nervous young woman that's quick-witted and incredibly handy with machines or other forms of equipment. Being one of the sixteen members of the Special Defense Unit (SDU), her duty is to defend Last Defense Academy from invaders trying to breach the school defenses. Tsubasa is kind and will help and support others the best she can, usually through her favorite medium of creating machines that can aid the team against the invaders or in regular daily activities. Serving as a support role for her friends comes out almost instinctively, as Tsubasa is weak-willed, crumbling under higher-pressure situations; instead of going in for what she believes, she will usually follow the group consensus or pass the decision to someone else. Her hesitation shows in her resolve, as she hates how fighting feels and would not do it if it wasn't primordial for survival. Her meekness is further emphasized due to a special condition that causes nausea and vomiting whenever she is stressed, with the effects being proportional to the emotional impact. Having been made fun of for her condition throughout her childhood, she finds it a very sensitive topic, avoiding mentioning it to others or disliking them if they make fun of it.

Tsubasa's true passion in life is mechanics and any activity that requires tinkering. Following in the footsteps of her grandparent, she spends most of her time working on machines, finding joy in things like geeking out about cars or designing new technologies. Being the thing that she enjoys the most, it's one of the ways she finds to ease her nervousness. If she finds a task, machine, or project challenging, she gets engrossed in her own work, reducing her awareness of surroundings, making her talk to herself or tools, ignoring others until they are right next to her, or pulling all-nighters to work, causing her to act snappy and a bit deranged. Another interest of hers is poetry; she had a phase during middle school when she wrote cheesy romantic poetry, though she completely hides it, and if someone found out, she'd die of embarrassment. Tsubasa prioritizes reliability and handiness in anything, not just in mechanics. She usually prefers handy food or something that can be eaten quickly, allowing her to eat while working or be quick enough of a meal to not waste working time. This means her diet isn't exactly the best, especially when she gets fixated on certain projects, as she will get fast food or junk snacks; even then, she'll always have a tea kettle whenever she is working for her breaks.

Tsubasa was born and raised inside the Tokyo Residential Complex, a sprawling, fully enclosed society that simulates day and night using an array of lights affixed to its dome ceiling. There, everyone is content, living regular, mundane lives and obeying orders sounded over the loudspeakers on every street corner unquestioningly. Frequently, announcements are made instructing residents to take cover inside dedicated shelters, which is so ingrained in their culture that no one thinks anything of it. Unbeknownst to the citizens, hulking monsters resembling disfigured stuffed animals routinely attempt to besiege the complex. Raised by helicopter parents, she spent her childhood being pushed towards success; as a consequence of this highly stressful environment, she developed her stress-nausea condition. Pushed by her parents, she spent her childhood doing various activities like piano lessons or swimming, which she was highly skilled at but didn't find any joy in doing. Tsubasa would find her passion after staying at her grandparent's workshop for one day; seeing him work with machinery sparked a fire in her, settling her true vocation as a mechanic. After that, she would move to her grandpa's workshop, living without the pressure of her parents and learning the skills of the job.

During one average afternoon, after not being able to find proper shelter during an announcement, Tsubasa was cornered by a group of the Invaders. Feeling hopeless, a ghost-like being on two legs named Sirei appeared and offered her assistance, enabling her class weapon, making her able to fight against the Invaders. With the threat gone, she was instantly recruited into the Last Defense Academy. She was instructed that, alongside her fourteen other classmates, she was entrusted with the responsibility of defending the school from the invaders and that the fate of all humanity hinged on their success. With invaders arriving around a period of 7 to 10 days, they are tasked with defending it for one hundred days straight.

The building, while high-tech, is entirely isolated from the outside world, and with just its fifteen troops occupying it, they're reliant on the mysterious hemoanima supplied to them by Sirei to defend it. Hemoanima is a blood-based power activated by taking a special Hetamorphic Infusion Blade to one's chest, which replaces their blood with hemoanima and affords them special weapons, called class weapons, and armor unique to them. Tsubasa's hemoanima produces a black-and-white seifuku school uniform with a black cloak, while her class weapon is a hemoanima-fueled jeep that lacks offensive power but thrives as a support unit. Her class weapon requires little physical aptitude and doesn't physically strain like others' hemoanima powers.

Back in the complex, Tsubasa's personality meant she wasn't lonely and usually had friends, but she always felt a slight alienation due to her vomiting condition, which she has always been sensible about, and because she never cared about what was popular with girls of her age, it left a gap with her female classmates. Instead she spent her free time in her grandparent's workshop helping in his job, which means she might not always be the most hip person ever.

Tsubasa has never been in a relationship or had any moment with a boy. Through most of her life she never found herself interested in romance, but as she grew up hearing her female classmates talk about their boyfriends and the changes of puberty, she developed feelings about having a boyfriend too, as something she wants to do but usually won't bring up to anyone, or if she finds herself in a situation where romance is developing, she will try to blow it off or act normal. While she thinks finding someone with similar interests to her would be nice, she mostly wants someone that's mature and desires a long-form relationship and not a one-night-stand type. Tsubasa likes being complimented and spoiled for the hard work she puts in and the resulting machines, especially if it's from someone that she considers special. She also gets flustered if someone acts gentlemanly, like a prince, or something similar.

Tsubasa is an average-sized young woman, standing at 162 cm, or 5'4", tall. She has long waist-level pale blonde hair that's usually tied for work, brown eyes, and softly tanned skin. With a weight of 120 pounds, her build is slim but not athletic, as her body is soft but in no way overweight, carrying a full C-cup chest and slightly soft waist and legs. Taking the ability to work comfortably as her clothing guide, her outfit consists of a black baseball cap with red markings, black fingerless gloves, white cargo pants, a black tank top, a black bow to tie her hair, and a white jacket that is tied against her waist.
