It takes dozens of hours by plane, car, and ship from Tokyo, and it is not even on the map, and the locals never go near it... a mysterious island. You can't land on the island except at high tide! In order to investigate the reality of the "Wild Naked Female Osase Tribe", which is said to inhabit the mysterious island, we challenged the most severe site in Hunter's history, and managed to land successfully with the cooperation of local fishermen. We immediately started searching the island and found a mysterious group of naked women!
