Synopsis
One cold day, I met a mysterious girl in a city park. The child, who calls himself Rei, holds a dead cat in his chest, and what he says is unclear. I tried to run away softly because it was for the sake of the person who was not involved, but before I knew it, I was caught up in the opponent's pace. However, this girl was actually a shrine maiden of a clan who had been purifying strange things that wriggle in the darkness for a thousand years. The only one who takes down God and defeats him-but the price the girl pays for it ... A funny but sad and sad story.
