When four-year-old Kun meets his new baby sister, his world is turned upside down. Named Mirai (meaning “future”), the baby quickly wins the hearts of Kun’s entire family. As his mother returns to work, and his father struggles to run the household, Kun becomes increasingly jealous of baby Mirai… until one day he storms off into the garden, where he encounters strange guests from the past and future.
