A man whose family and entire village was killed by a demon was given the task by, possibly, another demon, to hunt down and destroy that demon. Centuries later, he's still at it, and keeps arriving just too late to stop the demon from committing his latest assassination.
This is a horror story. There is no one likeable in it, except for possibly one individual that we are seemingly expected to regard as a fool. I may be being unfair, because I don't like horror, and should never, ever let myself be suckered into reading or listening to it.
Sometimes, though, I am.
Not recommended. Take that with a grain of salt because, as noted, I don't like horror anyway.
