Wazamonogatari

Around 600 years from the present day, a now-destroyed country was where the girl called the "Fair Princess" had lived. With such beauty that anyone would offer one's life for, the road the girl trod on became a mountain of corpses.
These are the legendary oddities! Oddities! Oddities!
Youth is cruel like a fairy tale.
