@Berdy
well it's easier to infiltrate a place and kidnap a person when it's just one or two people especially if those two are the leaders of their respected races
@Diamona The true meal was the friends we made along the way...meaning go eat your friends! They're tasty!
@Berdy Well, as you have seen, the leaders of each races are quite powerful. The human king and the hero. The demon king, his mother and all his children. They can basically take on the rest of the creatures all by themselves. So it isn't difficult to assume those two are really OP aswell. There is a very steep power balance in this manga where only a few people hold all the power in the world.
