The world is making a fuss about hegemony today, my readers.

It doesn't matter who has supremacy.
We did what we liked, how we liked, and did what we liked.

That's why I call myself this way. Prove yourself and introduce yourself.
This is a kind of self-harm, the name of what happened.


Yes, we are the "Demon King" ---


Oops, I was sorry for starting to talk so suddenly.
However, whether to call this world "the end" or "utopia" differs from person to person. There are those who call it a "miniature garden," and there are those who call it a "paradise."

If it feels like an apocalyptic world to you, it probably is. I just don't think so.

The only thing I can say is that this world does not belong to the gods, nor does it belong to humanity.
They are in the process of deciding who will rule this planet.

If we were to be defeated by the gods, humanity would literally perish.
No, it would be better to say it disappeared.
Every record, every memory, everything about humanity's existence in the past would have disappeared.

It's your role to stop it.

"Knights" are "immortal young people" created by humanity to resist the gods.
This is the story of you, the exceptional being ``Emperor'' who leads it.


Well, it seems like it's time. Shall we go now?


For the sake of humanity, which we should love and protect, let's go and destroy "another humanity."
Let's justify our history by pretending everything never happened.

It's okay, do whatever you like. Do what you like, how you like, and do what you like.
Because we-


It's the "Demon King."





The latest RPG "Reverse Blue x Reverse End" from Happy Elements and Grimoire is here.
The story is set in the 9th Orbital History of Humanity, which is the ninth time in human history that humanity was on the brink of extinction eight times and then survived.
