Appearance
He was a huge bespectacled ghost with a blotchy green form.

Personality
In life, he was a loser, and as a ghost, he was an unrestrained pervert. He also had a fondness for nice-smelling girls. When threatened, he became enraged by Mob interfering with his hobby.

History
While alive, as a youth, he was a loser who got nervous around girls. After becoming a ghost, he became content with life as an evil spirit and lived for himself.

Plot
He terrorized the Highso Private Girls' Academy girls, peeking at them in toilets and moving around their bras and panties. Mari and Chihiro then hired Reigen and Mob to get rid of him. After Mob trapped him in the basketball court, Scent-Ghoul attacked but was effortlessly repelled and then destroyed. As he was fading away, he likened Mob to himself and asked if Mob if he was living life to the fullest.

Like a typical evil spirit, Scent-Ghoul was capable of performing Poltergeist Phenomenon, being able to interact with the environment physically.

Trivia

 * In the anime adaptation, after being exorcised, Scent-Ghoul asks Mob if he lived to the fullest every day. However, due to his appearance being much later in the manga, this question was originally asked by Hiakru.
