あらすじ
Hellfire, said to be powerful enough to reduce the world to ash, has been sealed away. Flare, a young man living in the far north, was chosen as a sacrifice. Cast into the fire, he should've died instantly... but didn't!! Overcoming the flames of Hell, Flare has returned to the living world with the overpowered ability to summon Hellfire. How, he's free to venture out and see the world!!
