Season 1

Kurima Raizo, a samurai loyal to his daimyo, reflects on what he's done after finishing an unwanted quest, while talking to a complete stranger who seems to sympathize with his pain.

After exacting his revenge, Kurima Raizo finds himself aimless, but Usui Yuen has a proposition.

Raizo ends up staying in Nagasaki and Yuen decides to find a place for him to stay, but someone doesn't like that idea at all.

After settling in Soji's room for good, Raizo doesn't seem to leave the room and the reason is quite simple: lack of money.

Some children living in the mountains have started mysteriously disappearing, but unfortunately Yuen has no idea who is doing it.

After presenting their drawings and a potential source of income, Raizo and Soji are attacked on their way back.

Raizo still has not come to terms with the matter of Matsumine and his homeland. Meanwhile, there are other opium-related problems.

Yuen guides Raizo to the shelter where he began his activities to allow him to explore this path more fully, but the ronin shows signs of insecurity, though he is flattered. Is the life of an artist really for him? Faced with this difficult choice, he dwells on the past.

Due to the appearance of the third group, Raizo and the others will have to save Liu's life. And therefore they will know why the Chinese sought opium.

After Liu's death, Soji and everyone else are in danger due to a mysterious threat. Meanwhile, Yuen begins to have many doubts.

Raizo and the others remain under Shishido's behest of a group of revengers from another region as they try to uncover more details about Satsuma's opium.

The Nagasaki revengers decide to settle the opium case with Shishido once and for all and make a risky move.
