Plot

It's the spring of 1955 in Mitajiri (in the countryside around then small-town Hōfu) in Yamaguchi Prefecture, southwestern Japan. A nine-year-old girl named Shinko Aoki grew up hearing her grandfather's tales of life a thousand years ago, and is able to vividly see the past. Back then, a princess named Nagiko Kiyohara lived in the same village, at a time when the area was known as the province of Suō and its capital Kokuga. Shinko claims that her ability to see the past is a gift from the single cowlick on her forehead, which she calls her “mai mai”. Shinko invites Kiiko Shimazu, a new student who has recently transferred to her school, with her to her vivid imaginings of the past. Despite the girls' quite different characters – Shinko is an outgoing, exuberant tomboy, while the shy and city-raised Kiiko still mourns her deceased mother – they get along surprisingly well and end up learning from each other's differences.
