The cry of cicadas. Wind chimes ringing under the eaves. A country road shimmering in the heat haze. The sound of summer festival music drifting from afar.

A small settlement nestled quietly deep in the mountains.

There, a somewhat nostalgic and peaceful— "Summer" continues forever.

And then, the twin brothers Kagari and Akari.

Your precious childhood friends who you've spent every moment with since you were small.

Splashing water at each other in the river. Eating ice cream side-by-side on the porch when it gets hot. Heading home together as three when dusk falls.

A peaceful and happy daily life that never changes.

The two of them love you dearly.

Today, as if it were the most natural thing in the world, They smile at you innocently and gently, saying, "Let's stay together, the three of us."

—However.

In a fleeting moment, you might harbor a small doubt.

—Why does autumn never come to this village? —Why do the two of them hate the idea of going outside the village so much?

But such trivial doubts melt away into the dazzling summer sunlight and their gentle voices.

...Surely, you're just overthinking it.

So today, let's go out and play, the three of us.

There's no need to go outside the village.

Because the place you belong is right here.
