As Kazuhiro and Marie were being overcharged, Zera from the House of Thousand appeared.

He seemed to be an influential man, as the merchants were shocked to see him and immediately adjust their behavior given his arrival. Zera revealed that he had heard about them as the ones who discovered the labyrinth, sharing that with the merchants. Zera also oversaw the construction of their tent and lent them furniture. He was clearly grateful for Kazuhiro and Marie finding the labyrinth, saying they could call on him for a favor at any time.

The trio then came upon a myth painted along the walls, which depicted the Age of Demons, who were the world’s original living creatures before people.
