Practices, training, techniques
The Kouga have been operational in the shadows for a long time and have managed to continue doing so even into the 21st century. However, due to changing times, members of the school feel that they are nearing their limit. As such, they seek to obtain the means to develop genuine supernatural powers for the Kouga. However they are divided over how to accomplish this. Some of them believe that it would be faster to infiltrate Academy City to analyze supernatural powers with a certain faction having done so. Others don't wish to get so close to Academy City, not willing to submit to them for their leftovers, instead looking to investigate other factions.
