By force, she is taken away, separated from her family and friends. Now, between her and the people dear to her heart, there is a whole sea. But Ami doesn’t give up. A fragile, butterfly-like hope leads her, along with a desperate desire to change the familiar world—erasing once and for all all injustice from it. Will she manage to return home and help her loved ones before it’s too late?
