Nagasarete Airanto
After a terrible argument with his father, Ikuto makes a hasty, fateful decision to run away from home. Going from runaway to stowaway, Ikuto’s luck lands him on a ship heading right into the path of a huge storm! When it rains, it pours — or in Ikuto’s case, it pours so badly that he washes overboard and wakes up on a deserted island. Well, an almost deserted island. The island is populated by nothing but beautiful girls, all of whom want Ikuto to choose them as his bride.
