[Machine Translation] Shinnosuke, a mysterious samurai staying at a boathouse in Asakusa Hanakawado... He is said to have been a young lord of a certain Hatamoto (feudal lord), but was disinherited and came back to the city. If this is true, he is a real incompetent, but he seems to have no problem with it. He was living in a kimono, humming a song, and just going about his day-to-day life in a daze. However, this man was not only a Hatamoto, but also a young member of the Ujishima family, a feudal lord in Hizen, Kyushu, who disliked the riots in his own family and had left the warrior class to become an eccentric. Finally, Shinnosuke, in his element, found a new place to live... Shinnosuke finally showed his true potential and embarked on a freewheeling campaign to exterminate the villains in the streets of Edo. Touched by Shinnosuke's character, personality, and unparalleled strength, he begins to attract new friends one after another... This is the first volume of a series of "unprecedented period" stories!
