Nagasarete Airantou

ながされて藍蘭島

After a fight with his father, fourteen-year-old Ikuto Touhouin storms off to sea and is swept overboard by a sudden storm, washing up on the uncharted island of Airantou. He is found and revived by Suzu, a kind but scatterbrained island girl who takes him in. Ikuto soon learns Airantou lost nearly all its men years ago, leaving its young women starved for a husband, and his arrival sets off a frantic competition for him that Suzu keeps having to fend off.
