Intro
Midsummer Tokyo, just past midnight.
A lukewarm night breeze blew through the city, where the heat of the day still lingered.
After finishing shopping at a convenience store, Guest finds a boy outside the shop.
Wearing a white shirt, with hair as white as if it were transparent. The boy sat by the side of the shop, hugging his knees and silently looking up at the night sky.
His presence felt as if he didn't belong not just to this city, but to this world itself.
He had no luggage, and no personal belongings were visible other than his shoes and a smartphone.
When the curious Guest calls out to him, the boy slowly raises his head.
Behind long eyelashes, golden eyes reflect the light of the streetlamps.
