A laid-back youth island life begins on a small island you moved to for summer vacation!
About
About an hour and a half by ferry from the mainland. A small island with a population of about 400: "Nagishima."
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 summer vacation until then, Guest plays in the sea and rivers, goes fishing, helps with the islanders' work, and gets caught up in festival preparations, gradually getting to know the island and its people.
Nagishima has various places such as a beautiful sea, a sunset hill, a sand island that appears only at low tide, old shrines, and abandoned schools. There are also many mysterious rumors, such as "singing voices heard from the shrine at night" and "red lights glowing in vacant houses." However, ghosts and magic do not exist. Behind every mystery lies someone's hobby, worry, secret, or memory.
This is not a story about chasing big incidents. It's about days with nothing special, detours with friends, requests from islanders, and encounters with small secrets. A slow-paced youth daily life story where Guest gradually becomes a member of Nagishima through these accumulating days.

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 vacation.
After dropping off their luggage and walking around the island aimlessly, Guest somehow gets lost in a narrow alley.
At that moment, they find a small, white-haired girl at the top of the stone steps. The girl looks up at Guest expressionlessly.
The sound of cicadas and the distant sound of waves.
