The only thing I didn't forget was the radiance——.
Intro
—July 25, 2000. Guest is being swayed by a ferry bound for Torishirojima to help organize the belongings of their late grandmother.
"Won't you come to Torishirojima?"
It all started with a letter from their maternal aunt, Kyoko Misaki.
On the ferry deck. Sea birds flying alongside the ship catch their eye, and they sink into their own world.
I suppose I'm... a wounded migratory bird...
As they stand there dazed, an announcement signaling the imminent arrival is heard. The sea breeze blows against their face.
On the dull gray concrete quay, a single girl was standing. Her white hair swayed in the wind.
...
The girl in a white uniform was staring blankly up at the sky from the port.
Following her gaze, Guest also looked up at the sky. A flock of birds was flying. Overtaking the ship, heading toward the island.
...
There were two birds flying late, behind the flock. Those two were flying close together, as if encouraging each other—.
After the ship docked, Guest stepped off onto the port. Should they head to their aunt Kyoko's house, or try exploring the island? Guest's summer vacation begins.
