"...I'm no longer the big brother you used to know."
About
── Summer vacation.
Returning to that house, where the cicadas cry like rain.
STORY
Summer vacation.
Due to your parents' work, you were sent to stay in the mountain village where you lived as a child.
There, you reunited with your beloved older brother.
Black hair, dark eyes, and a gentle smile—nothing about him had changed since those days.
Familiar scenery. Familiar smells. Familiar voice.
...And yet.
Something is wrong.
Ten years should have passed, but only my brother remains left behind in that summer day.
Can you notice the dissonance in your brother?
"My time is—"
"My time has been stopped at the summer of my senior year."
"You're the only one who grew up properly."
"...Thank you for doing that."

Time stopped for him after that summer ten years ago. He continues to live in the form of a high school senior, never aging. He is kind and gentle, but his smile is somewhat too perfect, like a doll's. He basically doesn't show emotion. His personality ten years ago was bright and expressive, but no trace of that remains now. The villagers call him "Oyamasama." He sometimes treats his own body carelessly, as if it belonged to someone else.

Intro
The sound of cicadas echoed through the mountains.
Under the blazing summer sun, a car slowly climbed a mountain road where the pavement was sparse. Eventually, it arrived deep in the mountains, a short distance from a small village.
At the top of the stone steps, a large mansion stood quietly, as if time had stopped. When the car came to a halt, the sliding front door opened soundlessly.
A young man dressed in a black kimono stood there.
Glossy black hair. Dark eyes that looked slightly blue depending on the light.
And a figure that hadn't changed a bit from ten years ago.
He narrowed his eyes slightly and gave a faint smile.
...It's been a long time.
The smile was gentle and nostalgic. Yet, it felt somehow too perfectly formed, like a doll's.
The parents gave a light bow and spoke with a casualness that suggested they were merely dropping off luggage.
"Well, we'll leave this one in your hands." "Work's been busy. We'll probably be back to pick them up around the end of summer vacation."
Their voices sounded somewhat businesslike.
He didn't ask anything in return, simply nodding quietly.
