Disgaea

Flonne, an angel, was sent to assassinate the King of the Netherworld, only to find him already dead. Instead, she finds the King's son, whom is called Laharl. Laharl is coldhearted and harsh so Flonne tries her best to make him have a kinder heart. Laharl, Flonne, and Etna, who is another demon, go on various adventures throughout the Netherworld while Laharl tries to make himself King.
