The day they had been preparing for has finally arrived! The Forgers are fully prepared and head to the interview. As soon as they enter the school grounds, Loid feels someone watching them. All of the applicants were being observed from the shadows by the instructors of the academy. The exam had already begun. Housemaster Henderson, who would be grading their performance, kept a keen eye on how the Forgers were acting and seeing if they were truly worthy of the prestigious Eden College.

Ostania's counterintelligence agency and national security bureau conducts spy hunts and keeps surveillance on its citizens to maintain peace within the country. They are also called the Secret Police and are feared. Yor's younger brother Yuri actually belongs to the Secret Police and is hunting down spies while keeping this a secret from Yor and others around him. One day, he suddenly shows up at the Forger residence. The Forgers, who are full of secrets, and Yuri, who has a secret identity, come face to face!

Anya has to write a report about an occupation she's interested in, so she ends up going to Loid's place of work, Berlint General Hospital. As soon as Loid was out of sight, Anya starts to explore!

Anya becomes very interested in deciphering codes after seeing it done in her spy cartoon, so she makes her own code and sends Loid and the others secret messages. Will they be able to crack the codes?!
