Disgaea 5: Alliance of Vengeance has heroes from different Netherworlds working together to defeat Void Dark. Seraphina comes from the Gorgeous Netherworld while Christo dodges questions about his origin. We know he comes from a giant Netherworld and he’s a tactician. Christo befriends Killia, the protagonist in Disgaea 5, because Killia is his best chance at assassinating Void Dark.
Zeroken is a young overlord and a martial artist who is the heir of Goldion, the legendary demon fist technique. Killia meets Zeroken during a battle with the lost where Zeroken jumps in and helps Killia’s group (even though no one asked him to!).
Disgaea 5: Alliance of Vengeance comes out on October 6 in North America.
