Six Rules is a short story about a little boy, a little girl, and a spiritual journey through a snow-strewn forest of ancient Japan. The noble Japanese clan of Minamoto, with its centuries of heritage, had quite a few strict rules. Minamoto no Ryouji, a 12th-century Japanese boy of the Minamoto clan read those rules, and knew them all by heart. Never in his life would he even dream of breaking even one of them. That is, until that one day he met a girl named Yuki in the heart of the winter fields.
