"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.
