Is it possible for the roles of hero and demon to get mixed up?

Akuma Tiryns doesn’t know the answer to that question. What he does know, however, is that he’s had to live in utter isolation for three years due to being falsely accused of mass arson. His only companion is an angel that only he can see. One with an unhealthy obsession for saving others, and the power to force Akuma’s compliance. Playing the hero has now become his daily life, even as the people he saves call him a demon.

Until he meets a strange foreigner by the name of Sha Wujing—a saint searching for six legendary heroes to save the world. When Wujing uses her power to see Akuma’s soul, she sees nothing but pure, bottomless evil. The karma of Satan himself.

But apparently, her power has deemed him to be one of those heroes.
