During the end of the shogunate, there was a group of black-clothed masked samurai known as the "Crow Squad" who resisted the shogunate's oppression, taking down key figures one by one. During a Go game with a visitor named Seki Hikonoshin, the government inspector, Nozoe Minbu, was attacked and killed by what appeared to be the Crow Squad. The witness, Yoshi Goro, was also injured by their blade. Minbu's son, Katsuma, returning from a trip, learned of this and, along with his sister Sakura, vowed revenge.

Chikuzen, a ronin named Yoh Daisuke, after pacifying some ruffians at the theater of Onna-Kata Ogino Sawanojiki, formed a bond with the theater's bodyguard, Maruhashi Tadayasu, and Kaku, a priest. He ended up settling at the Kasugaya, the house of Oko, whom he had saved. When Oko decided to go to Edo, where her biological father lived, Daisuke accompanied her. Along the way, at Suruga Abe River, they encountered Sawanojiki's theater group, which had departed from Osaka earlier heading to Edo. A scuffle initiated by Tadayasu over a ferry boat with the students of Yui Masayuki but was amicably resolved through Masayuki's intervention.

In the town of Izu known for its hot springs, Den Shichi from Kuromon Town sets off for a healing trip with his companion, a bamboo craftsman with a nose like a lion's snout, at a time when the town is under a tight security network due to a nearby gunpowder depot explosion. Staying at Tsuruya, Den Shichi and his group are investigated by officials whose behavior seems somewhat odd. That night, a man looking like a craftsman is murdered, and gunpowder residue is found at the scene, prompting Den Shichi to suspect that something is amiss.

The head of Oshu, Harumichi Honma, was ordered by the boat bugyo (Commissioner of the board) Tajima Kuze to extract five gold coins to the Shogun family in Edo, and put it into Ryujin Maru. However, Tajima, who was the chief retainer of the shogunate, said that he was a member of the board, tetsugoro Funabashi, kumiyumi no Kami ichibei, and his son, masakichi, and others, and in the middle of the night, he killed all the members with poison in the night of the storm, threw Masayoshi, who was a fellow of the city, and masakichi, who escaped from the death of poison, into the sea and sank the boat to eliminate evidence.
