A long time ago, there was a magic book called the ‘epistula’ which was able to grant any wish, whether it be great wealth or eternal life. However, a sudden mysterious death befell all who had their wishes granted. It was believed that a shinigami came to take their lives. Over time, this tale gradually disappeared from people’s memories. Now, there are reports of a mysterious serial hunter and whispers of an urban legend around town. Rui watched as a student from his school disappeared in a back alley. Standing there illuminated by the moonlight was a shinigami.
