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. 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 ...

"Will you tutor meeee?"
Little sister doesn't understand her homework and asked for help.
It's a physical exam assignment from health and life sciences.
She was learning about human sexual development.. we looked at
the naked pictures in the book together...

"I don't understand... that... will you look at mine? Can you show me?"

Me and my imouto began her physical exam study.
