Disgaea Manga - Arashi Shindo

Prince Laharl wakes up from a two-year nap only to find his father dead and the Overlord's throne ripe for the taking. What’s a young prince to do but seize the throne, take over the kingdom, and rule with an iron fist? He may be new to the whole Overlord thing, but with the help of the demon-girl Etna and the ditzy angel Flonne, Laharl is determined to be the best ruler the Netherworld has ever seen. First, though, he’s got to get by the hordes of halfwit hellions determined to challenge him for the throne, foil an interdimensional plot, and keep his own vassals from trying to kill him. Soon, Laharl’s in an all-out brawl against both heaven and hell as he tries to keep his throne. This witty, exciting story features the appealing characters and wickedly funny battles that won the video game critical acclaim and legions of devoted fans.
