Sengoku Collection is a series of mostly unrelated short stories about samurai from another world wreaking havoc in this one. They do this not by fighting, but by being extremely eccentric. Each episode focuses on one character who is usually not seen again after that, but they are all complete stories, so this is not really an issue. There is an overarching plot, but it's sort of in the background for the most part. Sengoku collection is full of yuri, so steer clear if you don't like that. Otherwise, it's a beautiful, if strange show, and I highly recommend it.
