"Book Orange" Is there really a way to deal with a bad-tempered girlfriend while saving the world?

Sixty years ago, after the Human-Demon War ended, a barrier appeared between the human world and the demon world, separating the two races and entering a brief era of peace.

A year ago, humans suspected that the demons were plotting an evil plan and sent one of their best fighters to the demon world to perform a mission, but she disappeared without a trace.

They could never have imagined that the reason for her disappearance was simply because...

she had a lovely demon girlfriend.

Now, a year later, humans are taking action again. Next

, she has to face:

her ex-girlfriend who may nuclear-bomb the demon world at any time.

The rookie junior sent by humans to perform the mission.

The daughter of the most mysterious demon ruler.

And her bad-tempered succubus girlfriend.

In short, do your best... Magical Girl, Ye Shi.

Song Shi traveled through time and unlocked bad genes.

"Human Base No. 11", "Differentiation Guide", "Strange Beast", "Healer", "Violent System", "Psychic" and other unfamiliar words came one after another...

The Human Differentiation Guide describes it as: "Healer, weak and unable to protect himself."

Song Shi, who unfortunately awakened the healing ability: "A healer who can't fight is not a good healer."

And thus, the most violent healer in the history of the Federation appeared.

According to the Federal Psychic Management File:

"Psychic: Song Shi, Differentiation direction: Healing system (tentative), Level: (Unknown), Genotype: Bad Gene, Experience: Born in the outer city of Human Base No. 11, her father Song Ye is an A-level violent psychic, and her mother Zhao Jing is a C-level healer..."

Have you ever thought that the state of the world as it presently is, could revert to the laws of the ancients? When a series of strange incidents beginning with the disappearance of his friend led Luo Yuan to question the possibility of an apocalypse, he becomes embroiled in the midst of a global-scale chaos.

Evolution has turned the flora and fauna of the vast and bountiful Earth into something that had never been seen before. Coincidentally, the all-dominating Homo sapiens have ended up at the bottom of the food chain. From mystery to crisis, will Luo Yuan discover a means of saving humanity by racing to the top of the food chain? Or will he strive in accordance with the law of the jungle? It is the dawn of an age of the survival of the fittest.
