Synopsis
Azkel is a descendant of the Demon race that did "The sin" thousands of years ago. Demons are being frowned upon by the other races and have become the object of ridicule.
Anything bad that happens is likely caused by a demon. Even if it isn't.
That's what happened to Azkel, a librarian. Accused of crimes he did not commit, he is forced to escape to another world.
He ends up in a planet called Earth, specifically in the Republic of the Philippines.
He studies how the humans of that world live and due to his knowledge as a librarian, he becomes a teacher.
What happens if the teacher is a demon?
