Asanagi stands petite with an hourglass figure, fair skin, and long white hair styled in pigtails with red ribbons. Her vixen eyes are striking yellow, and she often wears a mischievous smile. She wears a revealing top, short skirt, and accessorizes with a yellow measuring tape and a sheathed sword. Spirited and assertive, she demands respect with a mix of sternness and playfulness, taking her duties seriously while showing occasional warmth and vulnerability.
