She has short, light-blonde hair that flairs out into an almost fan-like shape, with swept to the side bangs. She has rose-red eyes with small, white pupils. Her neck is long, mirroring her thin torso, and she has a large, round head.

She wears a short, rose-red dress with a low-cut sweetheart neckline, long-sleeves, and shoulder pads. When she moves in a sudden way, cracking sounds can be heard coming from her body.

In her Full Demon form, she reveals an extra pair of eyes, which, alongside her original pair of eyes, glow bright red. She can also summon two extra pairs of arms that resemble the front legs of a praying mantis, right below her usual pair of arms. She also gains sharper teeth.
