The hillsides of feudal Japan are no longer safe; men are being brutally murdered by mysterious, grotesque ninjas that don't seem to die, leaving a wake of terror in their path. In the midst of the chaos, a young girl named Rangiku wanders the land with a ninja named Manajiri, searching for the man who murdered her family and stole their most prized possession: a doll that has the ability to move on its own. With gruesome enemies to conquer and revenge at hand, Rangiku must use her skill of controlling her wooden dolls to destroy everything in their path, or die trying!
In feudal Japan, evil spirits known as mononoke plague both households and the countryside, leaving a trail of fear in their wake. One mysterious person has the power to slay the mononoke where they stand; he is known only as the Medicine Seller, and he vanquishes the mononoke using the power of his Exorcism Sword. However, in order to draw his sword he must first understand the Form, Truth and Reason of the mononoke. Armed with a sharp wit and keen intellect, the Medicine Seller wanders from place to place, striking down the mononoke in his wake.
Both of these are bloody horrors with lots of twists and turns in the plot. In both of these animes the horror comes more from disturbing ideas and situations than the blood and violence (although there is plenty of blood too). They both have innovative art as well.
