In a beautiful kingdom, along with her family, lived Princess Katjua. One day, when the princess returned home, the castle was attacked by terrible monsters, led by the demon king Mazokoguna. Wasting no time the demons made good fun of the female half of the population then took everyone else hostage, including members of the royal family. Upon learning of this, Katjua, in order to save them and keep them alive, became a slave of the demon king, unquestioningly following any orders. That Mazokogun is very obscene and sexually perverted - he didn't hide it himself! The poor princess, or rather her body, has to go through all the circles of hell.
