A Ronin (a masterless samurai) goes on a quest to find a stolen sword and restore the honor of his family's name, but, when it comes to pushing the limits of what is right in order to see his mission through, how far is too far?
The creature is Rübezahl, a turnip counter, and we'll see why you shouldn't trust people who love vegetables.
There are sword battles throughout with people bleeding and the like. A character threatens twice to end his own life in a ritualistic fashion but does not do it.
More spoiler-y, there is mention of a brothel and a character being held there. Additionally, a character accidentally kills a child by putting his hand over their mouth and nose in an attempt to keep them quiet.
