After the events of La Manchaland, Don Quixote and the rest of the sinners embarked for another adventure. Don Quixote was back to her cheerful and loud self as they went onwards.

After half a year, they were contracted by a bunch of people who had heard of their adventure against the bloodfiends and asked that they eradicate the bloodfiend family that had taken place into large theater with multiple rooms that served as an escape game.

With her memories as Sancho, Don Quixote wondered who could have created such a large building as they arrived at the theater.

At the entrance, a man dressed in a beautiful costume, his red eyes unmistakable. He welcomed the sinners with a smile and bowed.

Well-dressed bloodfiend: "Ah, Hello visitors. We have waited for you. Our human friends had warned us of your arrival. I am Nathaniel, the first child of our the Siren of the Aching Theater."
