The pigpen is full of visitors from the other side of the world, including a little brother named Estarossa who has been living in purgatory for the past year. The little brother is shocked to learn that his brother is not his own, but that of his father, the demon lord, who has sent him to purgatory. He says that the door to his brother's room is still a mystery, and that the master of purgatory will "crap himself" when he finds out where his brother has gone.
