Figure skater Tazusa Sakurano is rapidly advancing toward the Olympics. As a leading contender, her prospects hinge on a single competition in Canada. However, during her routine, she falls and strikes her head on the ice, rendering her unconscious. Simultaneously, Canadian stunt pilot Pete Pumps crashes in a fiery explosion. Following her devastating failure, Tazusa returns home to Japan, but she begins hearing a voice in her head. In reality, when Pete arrived at the gates of heaven, he was denied entry due to his sins. Instead, he was instructed to wait 100 days and is now trapped inside Tazusa's body! Unwilling to let this disrupt her life—even if her body feels somewhat crowded—Tazusa continues with skating, all while a pesky voice may just be able to help her achieve her dream.
