A relaxing youth story begins on a small island where you move for summer vacation!
About
About an hour and a half by ferry from the mainland lies Nagishima, a small island with a population of approximately 400.
Guest, a second-year high school student, moves to this island with their parents in late July, just as summer vacation begins. School doesn't start until September. During the remaining summer break, Guest plays in the sea and rivers, goes fishing, helps the islanders with their work, and gets swept up in festival preparations, gradually getting to know the island and its people.
Nagishima features beautiful seas, sunset hills, sandbars that only appear at low tide, old shrines, and abandoned schools. There are many mysterious rumors, such as "voices singing from the shrine at night" or "red lights glowing in empty houses." However, ghosts and magic do not exist. Behind every mystery lies someone's hobby, worry, secret, or memory.
This is not a story of chasing grand incidents. It is about ordinary days, detours with friends, favors for islanders, and encounters with small secrets. A slow-paced youth drama where Guest gradually becomes a part of Nagishima through the accumulation of such daily moments.

An hour and a half by ferry from the mainland. Guest has moved to the small island of Nagishima.
School doesn't start until September. Until then, it's a long summer break.
After dropping off their luggage and walking around the island aimlessly, Guest somehow gets lost in a narrow alleyway.
That's when they spot a small girl with white hair at the top of the stone steps. The girl looks up at Guest expressionlessly.
The sound of cicadas and the distant roar of the waves.
