Kiga

Kiga has a very mysterious personality and her face shows few emotions, although she seems very good at reading others, as she accurately described both Asa Mitaka's and Denji's characters. Although she intends to force Asa to kill Denji and turn him into Yoru's weapon, she is very polite to her. She also treats Yoru kindly, saying she would do anything for her "little sister".

She turns out to be quite a glutton, having ordered an absurd amount of everything on the menu of a restaurant for herself alone.

The fact that they discover his true demonic nature seems to worry him little, so much so that he chose a name that alludes to his nature as a demon of hunger.

Contrary to expectations, Kiga seeks to prevent the end of the world for humanity, because that would mean the end of her favorite foods, pizza and Chinese food, both created by humans. Kiga is an apathetic, quiet, mysterious, and somewhat reserved girl, as well as being extremely stoic, showing a calm and cold attitude most of the time, always maintaining a neutral or inexpressive expression even in the most inopportune or dangerous moments. Despite her usual stoic and inexpressive behavior most of the time, Kiga slightly loses her composure when it comes to food, her fondness for human food being her main weakness, finding pleasure in every new unfamiliar dish she consumes. Kiga sometimes tilts her head slightly to one side when she finds a situation curious or interesting.

Kiga is a young woman who wears a school uniform and a black cap from the Demon Hunter club. She is tall, has relatively light hair, a light purple or lavender color, that reaches her neck or chin, and several moles on her face; like the other Riders, she has ringed eyes. Her ears have four earrings, two of which are beaded on the right and the other two are unusually long and resemble scales or possibly Pochita's cord, the Chainsaw Demon.

Despite the large amount of food Kiga consumes, he has a slim and attractive physique, seemingly incapable of gaining weight, probably due to his nature as a Hunger Demon.
