The Prinnies are panicking because it seems like they’re about to wipe out, and just as Seraphina was prepared to actually take matters in her own hands, she sees the protagonist Killia appear in the middle of the two groups.
While we've seen parts of the Netherworld in other Disgaea titles, Disgaea 5: Alliance of Vengeance brings players to many dark lands. Killia, the protagonist in the PlayStation 4 game, vows to get revenge against Void Dark.
Disgaea 5: Alliance of Vengeance has a group of characters that come from different Netherworlds. Usalia, for example, hails from a Rabbit Netherworld while Red Magnus is from the Burning Netherworld.
Curry plays a big role in Disgaea 5: Alliance of Vengeance. You can cook curry before a battle starts to buff characters and nobody loves curry more than Usalia.
