While some creatures are very powerful, a rankings is a basic display of how strong the creature is, without having to describe its actual strength in full. A list is as such.

D rank: [5-25 points] They are incredibly weak, and a single slash from someone with more then 50 points can kill them with ease.

C rank: [26-50 points] They are stronger, and most creatures are within this range of power.

B rank: [51-75 points] Bigger and better monsters are B rank, they are hard to find, and difficult to defeat.

A rank: [76-100 points] Very powerful, they are considered the strongest of all of the creatures. They are not to be taken lightly, because they have such immense strength.

S rank: [101-500 points] The leaders of the monsters. Almost impossible to find, they are usually very wild and ly.

SS rank: [?-??? points] These are the Genesises. They are an automatic SS rank, for there extreme power. They can also be extremely powerful creatures, which rival extreme power.

SSS rank: ???
