—It was that simple a story. Armed with the knowledge and experience he has gained through Return by Death, Subaru seeks to defeat the dreaded Archbishop of Sloth, Petelgeuse, once and for all. The key to his plan: cooperation with knight Julius Juukulius. Can the two fight as one, defeat their cruel and detestable foe, and permanently extinguish Petelgeuse in body, mind, and spirit?
