Back when Dark Magic Dragonkin Lance had not yet left the Abyss, he once served as an elementary school teacher at the Demon Academy for some time. At that time, he would occasionally tell stories to the young members of the royal family.
The stories about the mini Underworld came from him.
Later, not long after he escaped from the Abyss, the mini Underworld appeared.
At that time, he and some other old monsters from the royal family suspected that Lance might have secretly created the mini Underworld.
But after some thought, they felt this possibility was slim.
How could Dark Magic Dragonkin Lance create a mini Underworld if he wasn't dead?
How could so many undead spirits of the Demon Race in the mini Underworld possibly obey the orders of a lower-ranking demon?
They also suspected that Lance met with an accident, was killed by a human hero, entered the Demon God's Paradise, and created the mini Underworld there.
