PLOT
In the era of the twelfth Shogun, Tokugawa Ieyoshi, a notorious bandit known as "Shippu" (or "Swift Wind") emerged in Edo. Shippu would send a warning message called the "Thief's Summons" before striking, yet despite the magistrate's desperate search efforts, they couldn't find any leads. One day, a summons was shot into the residence of Ono Ryusai, who was leading a peaceful retirement life with his two concubines, O-Ran and O-Koshi. With the summons, various individuals including O-Ran's brother Itami Shigoshiro, the master of the Muso-ryu dojo, vigilante Mankichiro, rope expert Gohei, and Den'ichi from Kuromon Town were assigned to monitor the situation. However, while they were distracted by a neighboring fire, a chest containing a thousand ryo was stolen, and O-Koshi was killed.
