(Urban supernatural fantasy, monsters run rampant, no System, no harem)
In 2163, I came home after finishing the college entrance exams, only to find my parents’ corpses…
The police found no clues at the crime scene, and it seemed the killer would get away with it.
But later, someone told me that my parents hadn’t been killed by a human. The culprit was a dog, or rather, a demon!
