Few monks have the will to study and learn this dark, and powerful fighting style and fewer still even use it's abilities. Many who have used these techniques have been executed for high treason, murder, heresy, and almost anything the law can think of. This dark, sinister style was created by a power-hungry mortal whose name has been long forgotten. In his travel he caught the sight of a monstrous demon whose strength and power had left devastation upon the mightiest of warriors. This creature belong from the Giant race and is closely resemble to the large Onis. However, where as normal Onis relay on trickery, deception and magic to help balance their size and strength, these Red Onis are quite a bit different from their Blue relatives. They instead focus their magic on increasing their incredible powers, becoming faster, acrobatic and even deadly than most regular Giants. Having observed the raging powers of a Red Oni, this mortal was able to tap in within it's most wicked, inner darkness and bring it forth up the world. This darkness soon created this intense, demonic form that increased all his physical abilities, while also dealing damage to both the body and soul. This style focus on drastically increasing your powers and dealing more damage, while also become more tougher and difficult to be harm. Once unleashing the full power of the Red Oni, monks have the capability to release great disaster to the land.
