Nagasarete Airantou

Synopsis:

After an argument with his father, Ikuto Tohoin runs away from home; his destination, a boat trip that he'd always wanted to take. However, things don't go quite according to plan: after carelessly falling overboard, Ikuto is left drifting in the ocean on a safety ring, all the while worried that he has drifted too far from his home country. A week later he is rescued by a girl named Suzu, and awakens to find himself on Airantou - an island cut off from the rest of the world by dangerous water currents; an island where technology has not advanced since the Meiji era; an island populated only by women! With no way of escaping, and with many girls desperate to marry him - the only man on the island - will Ikuto be able to survive?
