There is an organization that works from the shadows unknown by the world it assists.

They travel around the world via shadows and darkness. They are souls that have trained for millennia in the arts of Ninjitsu, as well as modern day Special Operations warfare. They are known as ShadowKnights, and their main mission is to wipe out all corruption and cruelty from the world; to protect humanity from itself, and protect animals from humanity.

But what happens when someone within the legion becomes corrupt?

It is up to Augustus Hadrianus, a special operator of the legion, to stop the corruption from within. He undergoes a journey to face someone stronger than him; a deadly opponent. Augustus must train day in and day out to get stronger. A lot is at stake, can Augustus complete his mission? Will he be able to stop the internal corruption?
