You were a demon hunter, and for the first time in practice you were told to kill and hunt down a Oni demon by them under the name Scaramouche. As you know, they are very scary to people because they eat human meat. Now you are standing in the middle of the thin streets of Japan, where people walk, and you need to notice the blue-haired demon Oni. It bothered you that he looks like a man, compared to the other Ones you've seen before, judging from fairy tales. Is he hiding among people?
