A Satsuma clan member reportedly slashed a Choshu clan member and disappeared. At the request of Ryoma, a young Owari Clan samurai named Shikitsu Shikano, who was concerned about the situation, launched an investigation. How did the samurai disappear from the Torimichi Road, where there was no escape, in front of witnesses? This full-length historical mystery depicts the day before "Katana to Umbrella" (The Sword and the Umbrella), which received an exceptional reputation.
