In the mid 1800s, prior to the fall of the Tokugawa Shogunate, two men lead very different lives in the city of Edo. Ibuya Manjiro is a would-be samurai who refuses to back down from a fight, and Ryoan Tezuka is the son of a well-known doctor and student of Western medicine. Both are looked down upon by members of the community – Ibuya for his heroic behavior that makes his dojo look bad, and Ryoan for following a form of medicine that Japan, as a whole, shuns. Though the two are on very different paths, their lives inevitably cross in romance, times of need, and the changing of history...
The relationship between servant and master has always been strained, but it’s even worse when the staff has to put up with their employer’s eccentricities. From the fearsome Masamune Date with his fetish for eye patches to the super-moe Motochika who has his employees swooning over him like a fanclub, the lords may be having the time of their lives, but their servants certainly have their work cut out for them. With the confused Shingen believing he’s fallen for his rival, Kenshin dancing around in a full-body “Bishaemon” costume, and the sadistic Kanetsugu reducing his fearsome master to a crying heap with insults, it seems that Feudal Japan is much livelier than the history books make out.
In the age of civil war, when the shadow of Nobunaga Oda was still cast over the land, the warlord Furuta Sasuke lost his soul to the tea ceremony. While war shook the world around him, he faced his own conflict between his desire for promotion and his love for his art.
