She has a determined expression for most of the time. Kaguya's height is stated to be 157 cm, and her three sizes are B79/W56/H81.

Kaguya's Astral Dress is mainly the color purple and has chains on her right hand and foot. The lower half of her body has a half skirt around her waist which drops to the knees and opens around her thighs. As for casual attire, she began wearing the Raizen High School uniform during her first date with Shido and later adopted the full outfit upon enrolling, including the vest. Aside from this, Kaguya is a fan of gothic lolita outfits. While her fashion sense has been noted to have become more mature by the time she entered university, she still prefers black clothes.
