He has written a book called "Assassin's Stealth Technique," which teaches how to use illusions to trick others. The protagonist explains that he is at his wits' end, and that he has performed everything he could to make the book a success. He tells the girl that everyone has fallen for a "scam" and that everyone is responsible for the minor mistake. He explains that since the union counterattacked, the positive news has been coming in one by one. He compares the situation to a game of hide-and-seek.

He claims that the king is too strong for him. The chapter ends with a description of the battle network that has been developed by the professor at the military academy.
