The other world is in chaos, the boundaries are broken, and evil spirits are escaping. A young man who encounters a monster saves the ignorant monster with a kind thought, and his fate is determined. The man told him, "In the beginning, humans are inherently good, and so are demons." He told him to be kind, and he never attacked weak creatures again. What is life for? What are the origins of human's seven emotions and six desires? The monster is confusing, so we are confused, so we are obsessed, so we are looking for it.
