Cerberus Rex, Nameless

In the woods south of the capital, a man born of magic wakes after a long sleep to experience his first taste of tragedy. Broken by the loss of one who cared for him, he becomes a monster he's never transformed into before. When he wakes up, a small rabbit-girl who calls herself a beast-bunny and a young man that smells of fear have cleaned the blood from his hands. Others' blood. But when he leaves them to mourn his caretaker and cope with the lives he has taken, he is shown the truth of his being. As a guardian called a Stag, he must venture into the world and make it better, but he will need to find the ones who helped him first.

The nameless one has never ventured outside of the woods before and, in his attempt to locate those he searches for, is arrested. It seems the capital believes them to be murderers, and if not for the intervention of a captain who knows what he is, Nameless might have failed his quest before beginning it. By the help of a demon, he reunites with those who cared for him in the woods, and he starts the seemingly impossible task of discovering what exactly happened to turn his companions into criminals and save them if he can.

If he cannot, he will have lost his first friends and the only ones he has come to trust to help him save their lands' magic and heal the world he finds falling apart all around him.
