Disgaea 2: Cursed Memories (Playstation 2)

Darkness is back. Overlord Zenon has cursed the land, and now, Veldime is transforming into a nasty Netherworld. Memories are sterlized, bodies demonized, the world is falling into chaos. The only one unaffected is a young man, Adell. He stands up to fight the curse, but things never go as planned. The haughty daughter of Zenon, a filthy little frog, lovable demon siblings and a washed-up rock star!? No one can ever predict what goes on in the world of Disgaea. And of course, other Overlords refuse to sit still watching.
