How about samurai vampire jack?
There's a legend about a road in the dark forest. No one remembers where it leads. Maybe to great riches, a beautiful new land, or a great library.
What is known however, that this road, littered with bones, rusted armor, and broken weapons, has a guardian.
At least a hundred years ago, a great warrior with a lust for glory and renown, was cursed with vampirism and a duty to guard the road. Hes even more dangerous, with immortality and a stronger blood lust.
The only to get by him and travel the road is to beat him in single combat.
No one has succeeded. Can you?
