Take me in and I'll love and serve you ~Sweet and sexy life with a demi-human girl~

I vividly remember my first time with an escort.

It was last summer, my wife and I divorced after twenty years of married life. I worked my ass off so I could support us so she wouldn't have to lead an embarrassing life of poverty. It was all for naught, though. She eventually confessed that she found me repulsive, and that she was cheating on me with a guy over twenty years my junior. I was stunned, but I wasn't angry. I wasn't sad. I didn't even find it to be all that strange. The years I spent toiling away as a wage-slave stripped the love I had for my wife along with it.

That's precisely why I felt downright merry the night following our divorce. I went out drinking on my own, wandering around downtown for the first time since my bachelor days. The city had changed just like I did. As I watched the youngsters who now laid claim to downtown, I realized someone was looking at me.

The gaze belonged to a girl much younger than myself. At first glance, she seemed like the kind of girl who'd look disgusted if she had to sit next to a middle-aged guy like me on the train. But she made no effort to distance herself. In fact, she approached me... "Looking for a good time?"

And so began the tale of a divorcee with an unparalleled sex drive and his escort escapades with five young, Saintly Sluts.

Shuuya lives with his younger sister Mirai and attends Academy Tengyou Daini. However, their peaceful days come to an abrupt end as their world is taken over by an alternate world called Waibin Sekai – one where angels and demons battle each other and monsters called ‘creators’ roam freely. The students are forced to decide to ally with the angels, side with the demons or do neither. No matter which choice they make, they would be hard pressed to survive in this dangerous world.

With his parents moving to America for work, Jinno Kyouji returns to his hometown, Kurehito City, after several years of absence to live with his mother's cousin, the free-spirited Saitama Yamiko. There, he encounters several girls he shares a history with.

Kazuyagi Akane, the strong-spirited tomboy he grew up with.
Namiki Aoi, a gloomy girl who's Akane's best friend.
Misono Kiika, a graceful, good-natured classmate of his from his old school.

In three years of absence, his hometown and its people have changed ever so slightly. Despite some hiccups, Kyouji's peaceful days in his hometown begin.

At least until he meets a mysterious girl on his way to his first day at school. Violet hair. Large, striking eyes. Skin that's paler than the driven snow.

"Welcome home," she says. "My name is Yuka. Remember it."

And wherever Yuka is, one mysterious, inexplicable figure is always nearby—a monstrous man by the name of Gore Screaming Show.

Kyouji's encounter with these two figures marks the end of his peaceful days—as they bring madness and despair into this world. Will Kyouji and the girl he loves be able to escape and return to their peaceful days? Or will they—

“Dear God, I now make this, the single request of my life…”
—–The near future, Nagasaki.
Into this city, with its long and checkered past
was born a rarity: a child with wings.
I don’t know when it started, but
The school overlooking the town
came to be known as hallowed ground –
and that is where we met.

Though summer comes closer, there is nothing new, and a boring day just rolls on. But, his boring life suddenly ends. He is forced to look for a key of the observatory.
