Story

The manga begins with the Great Hanshin earthquake of 1995, which the protagonists barely survive. Years later, during a school field trip to Nagasaki, the teenagers are thrown back in time to the Japan of the early Edo period. According to history, in 1637 a revolt broke out, known as the Shimabara Rebellion. It was led by a charismatic youth known as Amakusa Shirō, but ended in the defeat of the rebels and the loss of over 37,000 lives.
Natsuki Hayami, the heroine, is mistaken as Amakusa Shirō by the villagers she met, despite the fact that the real Amakusa Shirō was male. In the story, the real Shirō died the year previously, before gaining recognition or popularity as a leader. However, Shirō was a very feminine-looking young man and the recently arrived Natsuki physically resembles him a lot, so the villagers think she is actually him. Before long, Natsuki becomes famous as some-sort of heaven-sent angel and people started calling her "Shirō", believing she was the saviour prophesied twenty-five years before; she commits herself to their cause in an attempt to avert the soon-to-come rebellion, and gathers her lost partners as well so they can help her.
