In the rural Katsuno City in Hokuriku, the charred bodies of a couple is found in a crematorium. The police believed it was a joint suicide after a long stint of hospice care, so the case was closed. Six months after the incident, Ino, a magazine reporter from Tokyo, comes to Katsuno City for a story. While struggling getting anything out of the tight-lipped locals, he notices 3 things: Dark, distinct tire marks left at the local general store; the couple bought a new car only 6 months before the incident; and a suspicious elementary school student. Those 3 things are the catalyst that will lead to the true depths of what happened.

This one shot takes place between chapter 2 and 3 and was made to promote Jigokuraku.
