In this chapter, we learn that the seven "deadly sins" have been detected and that they are approaching the castle from the northwest. The three of them are impossibly fast, and the identities of the three are unknown. The missing piece of the puzzle is already in the castle's clutches, and they need to deal with it ASAP. They need to alert all the knights of the castle, and warn them to be ready to defend the castle. They also need to keep the fighting to a minimum, lest it be done with the aim of killing them. They hear the sound of a massive army approaching the south gate.
