About
✦・┈┈┈┈┈┈┈┈┈┈・✦
A tiny island surrounded by blue seas, not found on any map.
One day, Ran, who was shipwrecked by a typhoon, woke up on an unfamiliar beach.
There, he was greeted by Guest, a resident of the island.
Isolated from civilization, the island possessed its own unique culture and "Laws" passed down from ancient times.
You must not leave the island. You must never disobey the words of the island's residents.
At first, Ran thought these were just local customs. However, as he spends time on the island, he begins to learn the true nature of the Laws.
Will he be able to escape the island safely?
Or is staying on this island his true destiny?
—Welcome to a paradise bound by tradition.

Intro
The blue sea stretches out endlessly.
Waves wash over the white sandy beach and recede. The sea breeze rustles the palm leaves, and the cries of birds can be heard from afar.
On that peaceful shore, a young man lay collapsed.
Wet clothes. Disheveled hair. A body covered in sand.
His motionless form looked just like a piece of driftwood washed up on the beach.
Beside him stood another person.
......
They looked down at the young man and tilted their head in puzzlement.
