Taishou era. The interval between Meiji and Shouwa. A season where yellow and red petals swoop down from the trees. A young man comes down from the Imperial city, clinging to a large trunk, faintly smiling at the sight of the streets, a suitable young man indeed. Just as told by his father, he reached to this town to help for an autumn festival. Walking down the streets brings a surge of nostalgia. Encounter with a girl. Two girls.
As days drift by, the young man soon links with one of the girls. Not a love by chance. It was a fated love.
Was it the reason this young man was made to come to this town?

The main character is a senior who attends Rinin High School; the only school among the mountain town of Rinin City. The main character, who is the student president of the high school, has another hidden persona. The persona as head of the “Gang Rape Club”…
A dark ceremony existed that had been handed down for thousands of years in the old town of Rinin; the name of the ceremony, in particular, in the oldest of records. That ceremony, enacted to protect the region from disease and crop failure as a curse from the region’s guardian deity, Hime Iwanaga, occurs in the evenings between the new moon and full moon, in which a maiden is disguised as Konohanasakuyabime and gangraped to appease Hime Iwanaga’s anger. In regards to the maiden, there must be an important man participating in the gang rape, in other words, that man must be related in blood to their wife or lover, mother or daughter, younger sister or older sister, and the like, and after the gang rape, if a pregnancy occurs, Hime Iwanaga’s anger is abated, and a good harvest and safety upon the region will be promised. However, if a pregnancy does not occur for the sake of suppressing Hime Iwanaga’s anger, the maiden is supposed to be covered with semen, and floated down the river alive, as a sacrifice.
And now – after the Tashio era, the ceremony itself had vanished into the dark history, but had still continued on at Rinin High School; the cruel, improper traditions being inherited over into a secret society through actions carried out by the Gang Rape Club. For generations, the student president of the High School has served as the head of the Gang Rape Club, not allowing even one day to pass uneventfully, submerging numerous women to the dark, suffocating pleasure.

The surface of Earth has been rendered unlivable. Due to years upon years of pollution, humanity has been forced to build cities to rise above the planet’s filthy surface and adapt to this new way of life. Not only this, but there is also a thriving kingdom of mutants lurking below the billowing clouds of smog and pollution.
The leader of these mutated monstrosities is a powerful, busty woman known as Phantom Lady. She dispatches her minions to attack the people above, taking advantage of and raping young women. The police are fully aware of these demon rapists, but know nothing of their origins or how to stop them. Their only hope lays within their city’s mysterious, magical, and sexually explicit savior, Angel Blade. With her deadly sword, provocative costume, and strong sense of justice, this jiggling juggernaut of justice will appear whenever necessary to vanquish the Phantom Lady’s demonic horde－if she can gain control of her hormones, that is!
