The story is set in Bakumatsu and revolves around the Bunta Sugawara character, a yakuza (of course :) but instead of a modern yakuza/gangster, he's a gambler/bakuto). After he kills someone and gets wound, is saved by a blind woman (Mitsuko Baishô), who took care of him. They has a happy time under the protection of the Tomisaburo Wakayama character, an oybun. But of course, happy time doesn't last long. The story is also related to Okada Izo and the Shinsengumi (w/ Kondo Isami played by Makoto Sato)
The story of a young couple deeply in love with each other but, because of complications and misunderstandings created by the people surrounding them, they find it very difficult to achieve happiness.
