can someone recommend a good anime

I was gonna suggest Hakuouki Shinsengumi Kitan (which is a great samurai anime) but there's a lot of romance in it. Dunno, :/ you can try it if you want. I thought it was great, but it's really up to you...
However, though there is only ONE ninja, you can't go wrong with Sengoku Basara! If you haven't already seen it, it's based on a video game, which was based off of the actual history of Japan. Lots of cool samurai's and epic battle scenes. I linked the opening if you're intersted.
^_^ hope that helped!
