Onslaught!! The Demon Kings

Humans thought the apocalypse happened when the barrier between worlds had vanished. When, the world of fey, spirits, humans, and demi-humans became one. However, it does not end, in fact the world got more interesting as magic was introduced. Technological advancements became bigger as many feats becomes possible to achieve. But as soon as the final barrier dissolves introducing the demonic race to the world, people shun the demonic race.



No one likes the demon race and nothing can hope change the public sentiment whenever it is concerning the demonic race.



Then, two demon kings decided that, "It's time for another apocalypse"



"I will kill everyone who has no demonic blood"



"I will reincarnate everyone so they all will have demonic blood"
