This is a tale between humans and beings from other worlds. It is a story of ancient times. The Holy Knights who protected this country used immensely powerful magic. They were both feared and revered. However, there was a group who betrayed their country and turned their blades toward the remaining Knights. To the masses, they were known as the "Eight Deadly Sins."
I do not own Nanatsu no Taizai! It belongs to it's owners! This is just my fanfic.
