Gameplay.
"Disgaea 2" is divided into 13 chapters. Each chapter begins with cut scenes to explain Adell's next mission. Players then take control of Adell in his hometown of Holt. The town serves as a gateway to story maps, side quests, the dark council, and the item world. At the beginning of each chapter, a new area is unlocked. Each area consists of multiple maps which must be beaten to advance to the next chapter. Talking to the gatekeeper of Holt will give players the option of exploring the new area or repeating any maps that have been beaten. Many maps also have cut scenes. Scenes at the beginning and end of each chapter cannot be skipped. 
The gameplay in "Disgaea 2" builds directly upon that of "Disgaea: Hour of Darkness"; players control a party of characters to do battle on a 3D isometric grid map. 
The Item World game mode returns from "Disgaea: Hour of Darkness". Players can select any item in the party's inventory and enter it. The levels within are randomly generated, and the difficulty of enemies depends on the item's rarity or power. There are two ways to descend through the Item World: by defeating all enemies on a given level, or by using exit portals located somewhere on each level. Special enemies, called Guardians, can be freed by defeating them, imparting certain benefits to the item, such as increased attack or defense values. Once they are freed, they can be moved between items freely. The further a player descends through a given item's Item World, the higher the stat bonuses it will receive.

Fifteen years ago, a powerful Overlord by the name of Zenon appeared in Veldime and cursed its human population. Since then, all its inhabitants have become demons and are to remain that way if the curse was not broken. However, a young man named Adell was the only human unaffected by the curse. Wanting to save his family and return them back to their true form, Adell decides to seek out Overlord Zenon and defeat him. Adell's mother tries to summon Zenon and fails, but instead summons Rozalin, Zenon's daughter. They later go on a quest to find Zenon and return Rozalin to him, and then defeat him so that the curse would be lifted, making his family and the rest of the world human again.
