Hellcraft

Betrayed by the world, high school student Yeom Seung-gi shuts himself away in his room. Baphomet, the newly designated ruler of hell, chooses Seung-gi as his hell maker. In return for his assistance in creating hell, Baphomet grants Seung-gi the right to choose its prisoners. Seung-gi joins forces with the demon in order to seek revenge, expecting it to be a win-win relationship... Suddenly, a death game begins—to survive, they must be sent to hell!
