There is a grave, but it is no normal grave. As you go in, there is a castle.
Introducing Vampire Castle! The castle full of Vampires! All the vampires heard that you are intruding, so get to the exit quickly.
Even if you have 99 health and a Crysknife, you will still die quickly by spikes or shopkeepers.
1. Shopkeepers automatically get angry as you go into level 1-3.
2. Hell levels, even if they are not the main parts of the map, is playable. (Level 5-1 to 5-3.)
3. Yama's palace does not have a castle topping.
