The Sealer

In this world, there is a "Kegare Yaiba" created by the darkness that has accumulated in the hearts of human beings. The only person who can seal such a blade is called a "Fujinshi". One day, a man's beheaded corpse was found in Tokyo. There are traces of being cut with a sharp knife on his abdomen ... but no blood is bleeding. Mio Mijo, a young tabloid reporter, begins her interview to find out the truth of the case, but she suddenly witnesses the "black ashes" that spring from the corpse. She seems to be the only one who sees the "black ashes", and when she asks the detectives around her, she isn't dealt with at all. But ... Besides Mio, there are two men staring at "black ashes" ...! ?? Their names are Misa Shinki and Sho 500tsu. When they come, the case is always terminated and the truth is buried in the darkness.
