Hell School

Satan, Azrael, and Charon are sent to Earth in the form of ordinary high school students. Their mission? To lead the entire student body down the path of sin within a month! Only by maxing out the “sin bar” of every student will they be able to retain their titles as rulers of the Underworld. However, their path is blocked by Delia – a seemingly incorruptible girl capable of bringing love even to the hardened hearts of demons.
