Blood Destruction (血の破壊, Kekkai) otherwise known as Blood Break is an ability exclusive to the Werebeast race and allows for them to bypass all physical capabilities and possibly the laws of physics for a set amount of time.
Blood Destruction can be identified by the iconic red staining of the eyes, hair, fur, and parts of the skin (generally forming an intricate skin pattern on at least the forehead and under the eyes that are unique to each individual) with the red color is derived from the person's blood breaking from either the breaking of the capillaries or from the uncontrollable flow of their blood. After reverting back to his/her original form, the red coloring of their Blood Destruction form disappears thereby assuming his/her blood returning to the bloodstream.
Blood Destruction allows the Werebeast race to bypass all of their physical capabilities. Their agility and strength are dramatically increased during it and other races may even feel overwhelmed by it. Blood Destruction also gives Werebeast the ability to grasp all signals and movements, where they are able to predict the chance of a coin toss through all possibilities and factors.
After the use of Blood Destruction, the user finds it difficult to stand or move for a certain amount of time and will remain fatigued depending on the length of time it was in use. Regardless of who uses the ability, it appears to always wear out the user even if they have a great experience with its use.
