On the prime material plane rested a small blue marble made of dust and creatures who were convinced they existed alone in the universe. Just beneath their universe was another, the Underworld. Within the Underworld a vast cluster of worlds known as Netherworlds, existed. The primary inhabitants of these worlds were known as demons. These ambitious creatures strive for many things, power, lust, wealth, fame, and diplomas among them.

One such Netherworld was known as Blood Parch, and was said to have once been a dried and desolate husk of a world, that no demon wanted to live on. That was, until the day the Overlord, Logan the Mad, came to this world and breathed new life into it. Hundreds of years later, the now thriving world is home to one of the most prestigious high schools in all the Netherworlds. Hellmouth High.

Demons were a notoriously emotional creatures, and puberty was the worst, which is why they weren't allowed in to the formal education system until after their fifteenth birthday, when they were at the peak of their changes. By middle school puberty was over, and they had a grip on their emotions and their powers. By high school they were ready to learn how to become productive members of society. Some were destined to become the next great Overlord.

With summer over, it was time for Hellmouth to welcome a new batch of freshman, to its hallowed halls.
