### Summary
This chapter delivers a major plot twist alongside a moment of dark humor, shifting focus to intellectual and political maneuvering. A new character, Alicia, takes center stage with a stunning deduction, piecing together clues to reveal that the legendary lost Holy Sword is, in fact, a pen. This confirms the significance of the artifact that Emperor Key was previously tricked into trading away to the treacherous Chamberlain Shupen, who was working with the Grand Duke. The pen, now successfully retrieved, is established as a pivotal object of power. Juxtaposed with this revelation is Yuna’s attempt to soothe her brother’s growing loneliness. In a tender gesture, she gifts Key a pair of puppies, but in a comically cruel twist, she christens them with the very names Duke Ares had sentimentally chosen for their future children. The chapter masterfully combines a paradigm-shifting discovery with a character-driven subplot that promises hilarious future conflict for the main couple.
