It takes place between Kyoukai Senjou no Horizon and the City Series, two other series by the author.

After an accidental electrocution, Zhang Yi realized he could hide his body and become an invisible man. That incident marked a new chapter in his life. The magnificent president of the company, the hot policewoman, and the mischievous daughter of a rich man.“Apologies. I'm a righteous man. I've never abused my power of turning invisible to creep on beautiful girls, because I'd only stand boldly before them to look at them! You can't see me. You can't see me. You can't see me…”

A muffled murmur sounded softly,

Crazy goblins ravage the village,

Mutated beasts roam the fields,

The ancient old gods are gradually awakening,

Just when the darkness is about to engulf the entire continent,

A brave man from another world quietly appeared,

This may be the darkest hour before dawn.

Human: “The savior has come?”

Monster: “Have new food arrived?”

Till the fame of the brave spread far and wide,

Walking through every corner of the continent,

He/she/they know,

What is the real darkest hour.

The monsters and humans said in unison:

“I beg you to be human, the ancient gods were so scared that they went back to sleep.”
