Yato looked into a certain house’s living room from the window. For the first time in ten years, a branch of the Yase family gave birth to a demon master. The Yase family lineage was mixed with demon blood. They were able to see the unusual forms of demons that couldn’t be seen by normal human eyes. Every once in a while, a demon master appeared—they exchanged contracts with demons and employed them for use. In the living room of a Japanese style house, buried in a small down-filled futon, slept a baby demon master. Decorating the alcove was a christening scroll with the name “Tokimori” on it. It was an adorable name. The baby sleeping in the futon was surrounded by his parents and grandparents.

“I can’t see from here.”

Yato muttered to himself, as he passed through the window and wall into the living room. None of the family noticed at all when the 180cm tall Yato had suddenly appeared in the room, crouched down above Tokimori’s head, and looked into his face. The baby was fast asleep.
