I'm still so early in the game...but I think I'm figuring some things out about Killia. :) I just saw there's a DLC pack with "Disgaea 2" characters--which I'd love, but my PS4 will probably never have internet connection.........soooooooooo! XD
It's likely a Japanese smash-up word (as they do) of "discord" and "gaea" (earth)...since it's primarily about demon worlds (Netherworlds). XD The Japanese shouldn't smash foreign words like that!

I saw the lineart, but this looks pretty awesome in color!
