Death is just the beginning for our protagonist. 

Failing his suicide at a train station in Tokyo, George Serizawa is brought back to life as a half-demon and as the host of the archdemon and ruler of hell, Baal. 

He must use his recently acquired superhuman talents to fulfill the mission that Baal has given him: to track down and destroy the demons who have made their way to Earth.

Between living as a student and hunting down demons and their hosts, can he retain his regular life while embracing his unusual abilities and responsibilities? If not, will the burden of his destiny prove to be too much for him to bear?
