'Seinaru maki' or Holy Volume 1

'There was once and order that was labeled as 'Saint' which was led by Archangels and their chosen Knights who aid them in battle. This order worked against creatures that originated from the dark, who overtime gained power to rival an Archangel through multiple evolutions. These creatures are labeled as the 'Greivefang', weird bat and human like creatures, who the more human they become the more their power increased. They still hold some of their old animalistic like features but most of these features will disappear. At the time the order still stood, there was very few evolutions and there was thousands of these creatures, however after a long battle the creatures were driven to near extinction. Most of the evolved were killed and if they survived they were gravely injured, which in turn lead them to hide in caves deeper than most would travel.'
