Akuma Hashimoto was a compassionate, but timid young man. He respected his superiors, loved his family, and showed nothing but kindness to strangers he communicated with in his daily life.
But is that what he received in return? Not at all.
After a brutal murder, Akuma rises up as a lethal mummified assassin hell-bent on getting revenge on his killers and hunts them down through jobs that humans give him after summoning him from the underworld.
The only question is...will revenge allow his soul to rest or will it turn him into a spirit of vengeance without a chance of peace?
This is the story of Akuma's fate and his unfortunate internal battle between life and death, mercy and revenge, and love and hatred.
