Yuka, despite appearing childish and spoiled at times, serves as president and CEO of Kagura Total Security. Although she rarely embarks on missions, when she chooses to do so, she displays bravery, albeit inconsistently. Her expertise lies in the use of a crossbow. It's suggested that she may be older than her appearance suggests, having been with Kagura for the longest out of all its members, as depicted in the manga where she is seen in the background of an old photo of the first Kagua group.
