The year is
1963, Tokyo is set to host the 1964 Olympic Games, and Japan is trying to move
forward into the future. In a small boarding house overlooking the Port of
Yokohama lives 16 year old Umi Matsuzaki (voiced by Masami Nagasawa). Every
morning she wakes up extra early and raises a set of signal flags; a ritual she has done without fail for many years.
The life of
this high school girl has always been a hectic one, but she takes it all in
stride. Having to juggle house and academic work day in and day is exhausting, so a nice distraction is always welcomed. Such a opportunity comes in the form of a student protest over the fate of the old clubhouse building.
One of the boys leading the fight is Shun Kazama (voiced by Junichi Okada).
Umi’s experience running her boarding house allows her to become a central figure in Shun’s cause and the two start to develop strong feelings for one another.
Then one day, as Umi shows off picture of her late father, Shun makes a devastating
realization. One that wouldn't just put their relationship in jeopardy, it
would make it impossible. Umi and Shun’s dad may be the same
person.
If this turns out to be true, Umi and Shun must give up before they were ever given a chance.
