[Blank-Slate Girl] [Post-Apocalyptic] [Special Abilities] [Consistent Power Scaling] [Adventure] [Mystery] [Multiple Female Leads]
The story takes place at some point in the future.
An alien life-form called Qier invades Earth. Even after nuclear weapons are exhausted, humanity still cannot win.
Artificial intelligence and military robots are also powerless to stop them.
The alien creatures possess all kinds of special abilities and powerful senses. Only infrasonic waves can interfere with them.
The last remnants of humanity use infrasonic waves to build fortresses around the world. These fortresses are called Qiaer, where humanity struggles to survive.
But infrasonic waves cannot interfere with advanced Qier, so humanity's survival remains under threat.
I am a fortress builder, and I am also continuing my father's unfinished research into the use of sound waves.
After a long resistance, humanity is on the verge of giving up the fight. Just as humanity faces extinction, the female descendants of certain species on Earth unleash their powerful abilities. They are known as witches.
Witches possess all kinds of absurd special abilities. Among them, a witch parasitic on human physiology has also begun to awaken.
One utterly ordinary night, thanks to an unexpected coincidence,
I! Got scammed by an evil witch.
