I Promise To Kill You

Just on the out skirts of the kingdom of Genfilheim and deep in the heart of the wild life, an entity has embroidered herself as the embodiment of horror in the hearts of the common folk.
One day an odd adventurer, an aloof guy with a hearty smile and a carefree stride, marches into the very forest ready to see this supposed demon. But what happens when he discovers a tall and calm beast woman instead of the blood thirsty Beast he had heard so much about?
Well, what ensues is a sugary yet chaotic adventure of two people, a stoic beast girl who has lived many lives and the bubbly young adventurer ready to record every new experience he comes across. Their journey brings forth stories, some almost forgotten and others freshly sculpted, as they move forward with a peculiar promise in tow.
