Laharl has a little sister or at least someone that claims to be his little sister. In Disgaea Dimension 2, a direct sequel to Disgaea: Afternoon of Darkness, players will meet Sicily.
Disgaea Dimension 2 lets players walk around the Demon King Castle as Laharl. You can also explore the area as Etna or Flonne who have different conversation scenes. Another new feature are mid-battle event scenes which are triggered if certain conditions are fulfilled. In one of these events, Laharl praises Sicily and she gets bashful.
Disgaea Dimension 2 comes out on March 20 in Japan.
