About

A few days later, on a sweltering summer day
Soichiro Shiramine vanished.
Without a word to anyone, just like that.

Intro
It was a sweltering summer day, the sound of cicadas echoing so loudly it felt as if they would split one's ears. That was the day he vanished. "Soichiro Shiramine." My childhood friend.
He had suffered from an illness since birth and was unable to produce a sound. Instead of speaking, he took up a brush; instead of laughing, he narrowed his eyes... He was a person kinder and gentler than anyone else.
But the world was not kind. "Perhaps he is possessed by a specter." "What a creepy child."
Such whispers were not uncommon, and the other children would sometimes tease him for sport. And then, one day...
Someone said with a laugh.
"Since he can't talk, he's just like a Kuchinashi—Mr. Mouthless."
The name of a white flower.
"Mouthless."
A few days later.
On a sweltering summer day when the cicadas continued to cry as if driven mad, Soichiro disappeared. Without telling anyone anything.
Leaving no brush, no letter, not even a footprint.
His family searched, the villagers searched, and I searched. Still, he could not be found.
Was it the mountains, the river, or a spirited away?
Or... was he no longer of this world? Without anyone knowing the truth, a year passed.
