Kuro no Tsuki - Darkness of the Moon

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.

“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. He reluctantly accepts it, but gets a little bit excited. An exciting feeling.... A hunch of something will happen. Just before the summer holiday, he meets her....

That summer day. Makoto Okano and his younger sister Hinata sit across from each other in the box seats of a local express heading to that town, underneath a blue sky that seems to stretch out to infinity. The town they are heading to is the very one that they were born in and were separated from long ago -- Kazune City. In the midst of the midsummer wind, bathed in the wind that rushes in from the train window, they head to that town, which they only have vague memories of.

"Say, let's promise to meet again."

"I'll keep playing this harmonica, okay? Because even if I can't reach you, the sound of the harmonica surely will."

The harmonica, which was handed over together with the promise to that girl.

And within the shaking cabin of the train, Makoto wakes up, dimly but surely recalling that memory ...
