Disgaea 4 follows the story of former tyrant Overlord Valvatores, a vampire who has sworn not to drink blood for 400 years, now leading a rebel group against the Netherworld President. The political setting is the main focus of the game's storyline.

The game-play features from the previous games in the Disgaea series is still present, but new elements such as the ability of "grabbing" party characters in a tower fashion and throw them to reach otherwise out-of-reach places. Special abilities, like team attacks, can be used while in tower formation. Party monsters can still use Magichange to turn into weapons, and they can now fuse together with Demon Fuse to create giant versions of the combined monsters. The fused monster can also use Magichange and become a giant weapon for a party character to use.

The game's hub, Hades, can be customized to the player's liking. Characters found on Valvatores' captured land can be befriended and captured. A captured character can be disciplined (forced to perform some actions). it can then be used to find treasure, added to the party or released. Another game feature is the ability to create a custom pirate ship to reverse-pirate Item Worlds.

Disgaea 3: Absence of Justice is the third installment in the Disgaea series. It takes place in the same world as previous games, but in a different Netherworld. It tells the story of Mao, one of the top student of Evil Academy. In this school, being a rude, lazy student who doesn't attend classes is rewarded, while being helpful and kind is considered the traits of a delinquent. Self-proclaimed evil genius Mao is obsessed with the heroes of legends and wants to get his hand on their mysterious power: the power of love.

The gameplay is mostly the same as in previous games, an series of isometric maps on which the player's units (main characters, custom characters and monsters) move and fight to reach the next level. However, the characters now have specific weapon proficiencies, and monsters have the ability to turn into a weapon for their partners (magichange). Geo Blocks found on the map can now be stacked and stepped-on. Like before, these Geo Blocks affect the panel they stand on and the panels of the same color.

New maps and characters become available after the end of the game.

Disgaea D2: A Brighter Darkness is the sequel to Disgaea: Hour of Darkness. Laharl, now the Overlord, faces opposition from the Krichevskoy Group due to strange events in his realm. The game retains series gameplay elements like grid-based turn-based combat, combo attacks, and unit customization. New features include character relationships and the ability to ride monsters in battle. The world hub is the Overlord's Castle, where Laharl recruits vassals and accesses the Demon Dojo and Cheat Shop to enhance abilities.
