Sora is my name. There was another famous "Sora" in the history of Japan. He was a companion of Basho Matsuo (giant of Haiku (verse)) in the travel named "Oku no Hosomichi (Narrow Road to the Interior)". I decided to chase their route, because I am another Sora.
This is the 1st stage (next to prologue) of great series of jouney, another "Narrow Road to the Interior"
