Kiui and Mahiru have been friends since childhood. Operating under the persona of the Vtuber "Nox Ryugasaki," Kiui consistently promotes their belief in being the strongest individual. Kiui is adept at swiftly mastering any task, and all the skills they display as a Vtuber are their own.
However, these differences have led to them feeling somewhat out of place among peers. Mahiru is the only person with whom Kiui feels comfortable discussing the past without reservation, and is always willing to help dear friends.
