@Familia based on the hints they might not have technically lost. A theory I guess
considering the succubus queen knows the hero and she seems to have worked with him before all 5 race might have had an agreement of some sort maybe all 5 separated their world using those pyramid thingy which mentioned was build after the war but actually existed before the war(maybe he didn’t even fight a heck maybe the hero knew the real enemy which he told the other race and that’s how they all had their agreement
I still think the setting is a bit similar with MGQaradox though especially those enemy that appeared suddenly to stop them
I will never get used to ass-wings. They are completely nonsensical anatomically speaking and just imagining how it would look if they tried to realistically fly with those makes me chuckle because she'd hang in the air like a child that was grabbed by the belt ( for a good spanking).
