Tazusa Sakurano is a 16-year-old figure skater chasing a spot on Japan's Olympic team, but her tendency to fall at crucial moments has the media and public doubting her. At the same moment she takes a bad fall in competition, a Canadian youth named Pete Pumps dies when an air stunt goes wrong. Turned away at the gates of heaven for his sins, Pete is told to wait 100 days, and he spends them lodged inside Tazusa's body. What starts as an angry fight against a ghost invading her body and privacy settles into an uneasy coexistence once her attempts to get rid of him fail. With a voice in her head that might even help her, Tazusa turns her focus back to improving her skating and earning her Olympic selection. It's a mix of sports drama, romance and the supernatural, set against the clock of Pete's hundred days.
