In the year 1868, three young men join the elite Shogitai division of the Shogunate. The Shogitai fights to the end and opposes the dismantling of the feudal military dictatorship known as the Bakufu system.

The story is a variation on the Tom Hanks classic "Big," but instead of a boy finding himself in a man's body, a sick girl falls asleep one day and does not wake up again for 11 years. In the meantime, her baby sister, Natsumi (Rio Kanno), grows up to become a very studious and serious 12-year-old, studying hard at her summer juku (cram school). When her aunt, a free-spirited photographer (Karie Kahimi), goes missing in South America, her mildly scatter-brained mother (Kaho Minami) and father (Tetsuji Tanaka) go looking for her, leaving the girl, Natsumi, to look after her sleeping sibling, Ai (Rosa Kato). Yes, this is a clear case of child neglect, but Natsumi is such a no-nonsense, responsible type that it seems almost understandable. Soon after Mom and Dad leave, she notices that Ai, incredibly, is up and about, with the body of a woman, but the mind of an 8-year-old.
