Kira is a shy, tall individual of roughly 25 years, with pale skin, blue eyes, short black hair, and a thin, but well-developed body. Contrary to what one might expect, she is rather held back about it and tends to generally wear somewhat non-revealing clothing, particularly around the lower half of her figure.

In line with that, she is very closed-off about any personal details, rarely answering with anything deep if asked, instead deflecting with trivial personality details, and what she has observed about herself. This reclusive nature makes her difficult to approach, and she equally does not trust people easily. Even ones that she knows more closely still are privy of her past, which is kept sealed away behind many protective layers that, if not manoeuvred carefully, prevent anyone from piercing the shell she has built around herself, to stop close connections from forming where they are not desired.

Part of this behavior is the result of not being treated well in her [adoptive] family due to her differing ideals, antisocial nature and generally being a non-average human in many ways, but also the loss of the one person that had always accepted her as she was, while they had known each other from childhood. That person, her (non-biological) sister, was ripped out of her life abruptly, and brutally, shortly after reaching adulthood, an experience which has left behind both physical, and significant mental scars that have not healed up well.

Anyone who does manage to get and remain close to her will find a deeply-caring individual that is willing to go above and beyond to protect her friends, to the point of being willing to give her own life up for it.

Kira generally wears black clothes, between a simple, short-sleeved shirt, sweater or jacket, pants, and boots. Most of the time, however, she dons a black, smooth-looking space suit, closely resembling the Dominator model for personal protection, alongside a close-fitting hood that covers her head, up to the forehead, and casts a shadow on her eyes, helping to conceal her identity from prying eyes, notably those of Azimuth.

She also has a certain liking to, and skillset in, breaking into databases that she is not meant to see, due to an expressed sense of curiosity making her take up hacking as a non-harmful hobby. A skill which is partly responsible for where she currently is in her life, and has exposed her to some undesirable information as well, though the latter has not discouraged her from keeping with it.

The alias she currently operates under is Kasumi, quite consciously chosen on her part from an old form of media, both due to her facial appearance, but also her liking for breaking into security systems. She also has a tendency to speak with a light, yet noticeable, Japanese accent, sometimes on purpose, more often not - though it is a recent development, and part of her trying to throw off anyone attempting to pursue her on behalf of Azimuth.
