D.S. -Dal Segno-

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.

“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....

Gunjo Gakuen (Deep Blue School) is a facility designed to gather and isolate those students who got a high score on an adaptation exam (Scoring high on this exam indicates that the student is less likely to be able to be adapted to the society) mandated by the government.
 
After a failed summer vacation with other members of the school's broadcasting club, Taichi Kurosu and some of the other club members return to the city, only to find that all living creatures within it except for the club members have completely vanished. In order to confirm the status of the outside world, Taichi decides to gather other club members to help Misato Miyasumi, the president of the broadcasting club, who is trying to set up a broadcasting antenna to contact any possible survivors.

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 ...
