After defeating the demon Vyers, who refers to himself as the "Dark Adonis" and is renamed "Mid-Boss" by Laharl, he meets Angel Trainee Flonne. Flonne had been sent to the Netherworld by Seraph Lamington, the ruler of Celestia, to assassinate King Krichevskoy (who was already dead). Shocked by Laharl's lack of grief at his father's death, the eternally optimistic Flonne joins Laharl's party to determine if demons are capable of feeling love. Observing them in secret is the paranoid Archangel Vulcanus, who interprets Flonne's actions as treason and is convinced that she is plotting against him.
After Etna demands that Laharl pay the salary of the Prinnies that she has hired, he decides to attack the demon with the most money in the vicinity. This is Hoggmeiser at Dinero Palace. After defeating Hoggmeiser, Laharl is about to kill him, until Hoggmeiser's son rushes out and gets in the way. Flonne convinces Laharl to spare them, and Laharl lets them keep some of the money. In response to this act, Hoggmeiser joins the party.
At one point, Flonne and Etna discover a photograph of Laharl in an embarrassing situation. Laharl refers to this as a "paparazzi shot", however, the actual contents of the photo are never actually revealed. (Two popular theories are that Laharl was doing something sexual or that he was doing something nice) A threat on the back of the photograph states that copies of it would be distributed if Laharl did not accept a challenge to fight for the overlordship; thus Laharl was blackmailed. One of the demons in Laharl's castle, after learning about the photo, says "I didn't know you were into that sort of thing ♥".
Responding to this challenge, Laharl meets Maderas, a vampire. He was banished by King Krichevskoy, for stealing the King's favorite snack, black pretzels. Maderas takes advantage of Laharl's two biggest weaknesses – optimism and women with sexy bodies. Maderas was also controlling Etna by holding her memory. He had instructed her to kill the prince, but she had put him to sleep for two years by poisoning him instead. Etna eventually betrays Maderas, and along with Laharl, Flonne, and Mid-Boss, defeats him.
There are a variety of weapons in this game such swords, axes, bows, guns, gloves, staves, and claws(which only monsters can use). Each time you use a weapon from weapon class you gain experience with that type of weapon which all goes towards unlocking skills that use that type of weapon. Examples include Blade Rush for use with the sword class and Boulder Crush for the axe class. Staves, however, do not give level to give you skills, instead increasing the range and power of magical skills. Monsters also do not increase their skill levels with weapons, instead learning their skills at pre-set levels.

Afternoon of Darkness features extras over the original title such as a 16:9 format, to take advantage of the PSP's widescreen display.
