"Let's dance in this harem."

- Sateriasis Venomania

The Lunacy of Duke Venomania is a song released by Akuno-P on July 25, 2010. It is a part of the Seven Deadly Sins Series, depicting Lust.

Plot
The story takes place in Asmodean as Duke Sateriasis Venomania greets another woman who approaches his mansion. He explains how he made a deal with the devil to have an irresistible charisma to women; as a result, women flock to his mansion's basement to create a harem for him. The Duke burns all his old portraits, revealing how he had been mocked and taunted in childhood for his appearance. He kisses another girl in his harem, Gumina Glassred, who had been his childhood friend but also made a fool out of him. He continues to build his harem and women begin disappearing from all over the land.

One day the duke greets a new woman entering his mansion, approaching "her" to dance; as he does so, however, the "woman" stabs him with a knife, revealing himself to be a man who had tracked down his lost love to the Venomania's home. Due to the injury and the knife's poison, the duke collapses and his spell breaks; as a result the women all begin to flee the mansion. As Venomania dies, he sees a glimpse of Gumina and he begs her to stay, as he states that he has not yet told her that he loved her.

Composition
The song is made with the various VOCALOID and VOCALOID2 programs. It utilizes Camui Gackpo as the main role, as well as KAITO, MEIKO, Hatsune Miku, Megurine Luka, and GUMI.

Conceptualization and Origin

 * The term lunacy means "insanity", tying to the Duke's wanton sexual abuse to satiate his own pleasures; the word also means "foolishness", possibly due to being deceived by Kachess because of his own arrogance regarding his power.
 * The name Venomania is a combination of the words venom and nymphomania, meaning "an excessive desire for men", referring to his power over the women he enchanted.
 * The song's English title, "Dance with Asmodeus", is a reference to Asmodeus, the patron demon of Lust; it also references the Duke's signature phrase before dancing with the women in his harem.

Curiosities

 * A manga based on the song was serialized, acting as a prequel to the song's novel adaptation.
 * After each chorus in the song PV, a list detailing the missing women in Asmodean was shown, revealing Venomania's increasing depravity; after the second chorus, his victims include a 62-year-old woman and three girls with their ages censored, one whose age is in single digits.
 * Many of the women's name, ages, and occupations reference characters from Story of Evil; a majority of the lists' names are based on the name of a female Vocaloid.
 * Josephine Francois, who has both her age and occupation censored, is a reference to the horse owned by Riliane Lucifen d'Autriche in The Daughter of Evil.
 * Ironically, the song echoes Venomania's earlier comments of his "libido that hid poison" and "pleasure of the blade that cut", which mixes his blood and sweat together until it turns purple, at the end of the song, where he is stabbed by a blade hiding poison, causing his blood and sweat to mix together until it turns purple.
 * The song was rearranged by mothy, titled "The Lunacy of Duke Venomania [Remixed Version]", a track included with the purchase of the manga.
