Lupercalia of the Silent Accord

After the surface of the world broke down, the city of Novus Aether floats in the sky, thanks to the prayers of the Holy Maiden. Years ago, when the Holy Maiden's prayer was interrupted, an incident known as the "Gran Forte" occurred, causing a portion of the land to fall and split the lower city into two, separated by a cliff.

In time, the lowest layer became the dwelling of all kinds of low-lives, people who lost much of their former lives during the "Gran Forte", becoming known as the "Prison". However, a contagious disease which causes people to grow wings has spread throughout the city, and a unit has been formed to deal with these people swiftly.

In this "Prison" resides Caim Astraea, a freelance ex-assassin who does odd jobs for his friends for money, refusing jobs that require him to kill people. During one request, Caim finds a girl who contracts the wing-disease, enveloped in a light that reminds Caim of the “Gran Forte” years ago...

Let’s make Yuto our shared penis☆”
 
Spring. The boy, Yuto Amemiya (you), who started living alone after his father moved to a new place, is spending his days freely, although there are a lot of hassles. Perhaps it is because he has been living alone with his father for as long as he can remember, but he often felt a sense of loneliness at the spaciousness of the family-type condominium immediately after he started his new life, but he soon got used to it. It may be thanks to the wives of the neighbors who took care of Yuto in their spare time.
 
Megumi Morisaki, a beautiful ex-Yankee widow, is a little bit foul-mouthed but very caring.
Anna Okudera is a beautiful, intellectual wife who has a problem with being too uptight.
A calm, gentle, motherly, goddess-like beauty – Mako Suzumoto.
 
Although different in type, these three wives have been close friends since their school days.
You help them with anything they need, as they tend to be short on male helpers due to their own circumstances.
The three of you, who don’t know their mother, are always there to take care of them, sharing dinner and other things with them.
Peaceful, calm days, holding each other’s hands.
 
Then the seasons change, and it is summer.
The summer vacation is just around the corner, and when the three of them learn that you will be spending your birthday alone, they decide to celebrate your birthday with you.
You ask, “Is there anything you want for your birthday present?
You whisper in a sweet voice to your Mistress, her cherry-red skin glistening with alcohol, and you say something that you’ve been meaning to say for some time.
 
I want to have sex with you.
 
You watch with bated breath as she realizes that you, who she thought was a child, are in fact a full-fledged male, and that her face is changing from that of a man’s wife, to that of the parent of a child, to that of a woman. …… And then you know.
That the wives are former slutty wives who have graduated from the flower garden of sex-loving JKs called St. Slutty Academy.
 
The sweet, sweet summer vacation begins, where the heat of summer and the heat of your skin meld together like caramel.

One day, a young chef Raylan and his mentor went together to the mountains to gather ingredients. Little did they know that they would encounter a heavy thunderstorm, and a hostile scouting party. In order to escape pursuit by the enemy, Raylan ran for his life in the mountain forest. Soon afterwards, lightning started a fire around an area, and he stumbled upon a large hole in a tree. Inside, he encountered a mysterious girl in a deep sleep who resembled Sleeping Beauty, but before he could wake her up to find out what happened to her, everything turned black for some reason...

Life has been nothing but Ls for protagonist Koichi Hirose.

Back in college, his first-ever girlfriend dumped him outright, and he ended up dropping out altogether not long after.
Now he’s just trying to hold down a job to make ends meet, but for some reason, every company he joins goes under...

So when his latest hard-won job vanishes overnight (again), he heads to Akihabara for some aimless daytime distraction...

No savings, no career, no girlfriend. Where did it all go wrong?

He sighs into the crowd, then to no one in particular—

“...I sure could use a little love right about now.”

In that moment, only feet away, Mami Mamiya is searching too.
This pink-haired succubus is on the hunt for a human connection.

Not just any connection, but a male with certain innate powers.
Despite the odds, she finds him at once—in our protagonist, Koichi!

And so the story takes a demonic turn.

Tempted by fate and a mysterious invite from Mami, Koichi hitches a ride with her to her remote mountain home.
Little does he know that he might never return...

Or will he...?

Koichi is shocked to find that he’s in no ordinary human village.
He is now in a succubus sanctuary of sorts, hidden from human eyes.

Why Koichi?

After years of self-imposed isolation, a human male is just
what Mami’s village needs to reacquaint with the outside world!
Even touching succubi, however, can be lethal to the average joe...

Not our Koichi, though. This boy’s built different.
With the village’s blessing, let the succubus sessions begin...
