Gods and demons who could not intervene directly hoped humanity could use "astra" to develop technology and, through their own efforts, overcome the fate of destruction decreed by the stars.
The future humans who obtained "astra" did not disappoint the gods. They successfully developed the "Third Permanent Mechanism," built environmental control towers, and solved the problem of the stars' breath.
Then... they caused a huge disaster.
Having successfully avoided the stars' breath, humanity created a catastrophe that even the million-strong pantheon found utterly terrifying because they could not control the power of the Third Perpetual Motion Engine.
They were three Demon Kings closely tied to Humanity's Final Trial and the Third Perpetual Motion Engine.
—The "Absolute Evil" Demon King, Azhdaha.
—The "Sealed World" Demon King, Dystopia.
—The "Decadence Wind" Demon King, Final Nihility.
The first Demon King had repeatedly surrounded the million-strong pantheon alone. The second had beaten the gods and demons of the western district into outright surrender. The third was an absolute monster who, when enraged, would even wipe out the other Humanity's Final Trials.
Looking at it that way, there seemed to be nothing wrong with the Demon King Alliance Ouroboros wanting to rebuild a new Little Garden. After all, each disaster caused by the Third Perpetual Motion Engine was more outrageous than the last. It was practically impossible to see any chance of overcoming them.
After much difficulty, the strongest martial god appeared and forcibly overcame two of them, giving the gods and demons of Little Garden hope. Yet who could have expected that he would turn around and become the most vicious rakshasa who devoured Demon Kings...
"Enough. There's no point talking about that now. What we need to do is end this quickly, find the core of this world, and suppress Little Seven."
