Nadeshiko Island is a place of exile for itsuwaribito. All kinds of itsuwaribito are exiled there, no matter what their crime. Whether it be minor or serious, every person sentenced is forbidden to return to the mainland until their term is up. The most serious criminals, usually murderers, are branded with a special pincer-like tatoo next to their mouth. The island is hidden deep in the mist and is surrounded by cliffs, which would make escape difficult. The ocean currents all flow toward the island, which prevents anyone from escaping on their own. Once a criminal's term is up, the local authorities will come to collect them in a large ship, before returning them to the mainland.
