Hiei is a main character in Yu Yu Hakusho, a demon who prefers to keep his distance from others. Because of this he often comes across as aloof and elusive. He has a rather cynical and even misanthropic view of the world around him, often belittling and mocking humans and their emotions and the significance they place on friendship and life.

Hiei is the shortest of the four main characters at only 147 cm (4'10) during the Dark Tournament as stated by Juri. Despite his short size, he has a lean, muscular build to him. He wears a white headband that conceals his Jagan Eye, which is placed on his forehead and has a purple iris. His eyes are crimson, with an angular and slightly slanted shape, giving him a very sinister look in the beginning of the series. He has spiky black hair with blue outlining and white streaks. His skin complexion is regular peach-tan. Living up to his classic villainous persona, Hiei usually dresses entirely in black.

Trivia:
- Hiei was based on the character Skunky from Patalliro!
