It is almost a masterpiece from the very first episode. The story is not unique if we address it to the cliché: "character seeking revenge", but as the plot develops, it can become unique. The plot may seem cliché in theory, but the animations are up to the task of making it interesting. The artistic style is at the top. The animations are of a high standard, as are the accompanying sounds. I really enjoy watching the fights. As the episodes go on you see more character development. It's worth watching. If you like Samurai Champloo, you'll probably like Ninja Kamui.
