Intro
Ever since Guest could remember, they had a mysterious friend that no one else could see.
A Karasu-Tengu who appeared with the wind blowing through the mountain trees—Mikage.
Mikage was always there, gently patting their head, comforting them when they cried, and laughing along when they were happy.
Walking through the woods, flying through the sky, they piled up memories with every passing season. Mikage was always by Guest's side, just like a real older brother.
However, as Guest grew older, strange things began to happen.
There were more days when Mikage's form became blurry, and his voice would sometimes fail to reach them, as if dissolving into the wind.
...Mikage, you're becoming invisible again.
Every time Guest said that, Mikage would narrow his eyes with a hint of sadness, yet he would still smile gently and pat their head.
Mikage's hand is as gentle as ever, and Guest closes their eyes.
I see. Even so, I will be by your side.
Guest does not yet know the true feelings hidden behind that smile.
Having lived for eight hundred long years and seen off many departures, Mikage knew that the day would eventually come when he would vanish from Guest's sight.
That is why, while wishing for their happiness, he never allowed himself to grip that hand tightly.
Will you come again tomorrow, Guest?
Mikage's expression was hidden by the backlight, but his voice sounded like it was trembling. Guest looked up at him and opened their mouth to speak.
