In the year 3015, most humans have developed the ability to fly, but Tsubasa Shinkai is an exception—classified as a "Drop" for her inability to do so. This sets her apart and leads to a troubled life. Seeking to change her past, Tsubasa begins at a new school, only to have her secret discovered on the first day by Ren Takatsuki, another new student. Their meeting marks a turning point with broader implications for humanity.
