I've read a couple of volumes from the manga, and looking at the trailers it seems to have a decent amount of action and violence. The manga was a bit hard to understand and follow, but I think the anime will be more straightforward and you should be able to tell what is going on easier.
http://amatsuki.com/Ordinary high school student, Tokidoki Rikugō, has to take supplementary History classes, to boost his failing grade, at a state-of-the-art museum. This museum allows the visitor to use high-tech virtual reality to reconstruct a realistic Edo period. However, once the simulation begins, Tokidoki is attacked by a strange creature. After something happens to his left eye, he realizes that he is not wearing the VR goggles - it is no longer a simulation; he's trapped in the past and has no way of getting back.
