Synopsis: Nagasarete Airantou

Ikuto Touhohin has just had a final confrontation with his father, resulting in a hasty choice to flee from home. He boards a vessel, intending to enjoy a vacation, but suddenly, the ship is struck by a massive storm—one that throws Ikuto overboard! Upon regaining consciousness, he discovers that he is still alive... on an island. A remote island. A remote island inhabited solely by girls. Marooned on an island with only girls, devoid of electricity, gas, radio, or television... as if he had been transported back to the stone age.
