In the year 1923, Takiko Okuda is living in a small Japanese town with her dying mother, while struggling with feelings of loneliness and heartbreak. After a long absence, her absentee father finally returns home with a mysterious book named ‘The Universe of the Four Gods,' which he has spent years obsessively translating. When Takiko's mother dies, Takiko vents her frustration and anger on this book her father seems to value above his family; and to make matters worse, she's then transported into the book and finds herself called the Priestess of Genbu. However in this land of Hokkan, the Priestess and her seven celestial warriors are not welcome; Takiko must overcome many trials to save this other world that does not seem to want her.
Although the stories are kind of different, many of the overall ideas are the same; a girl gets caught up in a sea of trouble involving magic and other things that would have been way over her head in the beginning. Also, there is a tug-of-war romance going on between a girl and two guys. Last but not least, the artwork is quite similar.
