Koichi Fukuda

A princess finds life behind the protection of her brother and the high walls of the mansion to be quite dull, so she takes on another identity and lives in a small house in Edo pretending to be a singer but all the while she is actually a Shogunate Detective. Framed by a crooked magistrate for a crime she did not commit, Oshichi must clear her name of false charges after a woman helps to lead a prison break of the notorious Oshu Remnants. Meanwhile the magistrate, Lord Kai, conspires to be rid of her brother, Clan Elder, Lord Abe Iyo. Her only clue is an ornate dagger with a handle made of golden coins.

A princess in disguise, Oshichi launches an investigation to reveal the truth about the disappearance of young women in Edo.

After the Onin War ended in 1477, Kyoto was left in ashes and the nation was in complete disorder. Bands of roving samurai called the "nobushi" terrorized the country under the leadership of Akagaki Genba and overthrew Mangetsu Castle in Tanba Province scattering the few survivors. Lord Niwa's two sons have been studying in China and return to Japan upon hearing of the tragedy in an attempt to restore the clan. On Mt. Oe they meet magician Kiri no Kojiro and try to enlist his aid. With touches of the supernatural and rousing sword-play can they succeed against the evil villains whose symbol is the skull mask?
