First things first, this anime is about people that turn into weapons and the people who use them to fight. This anime has a lot of well executed fight scenes that make for an enjoyable watch while at the same time keeps a nice Halloween like theme to it that adds to the semi-creepy setting. I say semi creepy because there are moment that are purely comical.
The setting is really nice and adds the darker elements to the show. The show's fight scenes also add to the setting with most of them taking place either at night or in dark areas. The weapon designs for the show also add elements to the show that really completes the Halloween like setting.
The characters are an interesting bunch. They vary from the smart and confident to the relaxed and cocky. Each character has certain traits to them that distinguishes them from the other characters in the providing moments where they either truly shine or just completely displayed with comical reactions.
So basically, this is Halloween the anime. It's filled with monsters, killers, witches, and even zombies. While it isn't the most creepiest anime, it still has a Halloween theme to it much like the a Tim Burton film, but that's just my opinion. I highly recommend it as it was a really good watch.
