Twilight is an agent that works for WISE, Westalis's intelligence agency, and he is tasked with investigating Desmond, who is in Ostania and planning to start a war. Twilight disguises himself as the psychiatrist Loid Forger and adopts a girl named Anya so that he can enroll her into the prestigious Eden College to get closer to his target. Unbeknownst to him, Anya is actually a telepath who can read people's minds. One day, members of a mafia group that is after Twilight kidnaps Anya. Loid realizes that he needs to reconsider his priorities and...

Civil servant Yor Briar has a secret identity: an assassin named the Thorn Princess. Lately, single women had been suspected of being spies, which was making Yor nervous. Meanwhile, Loid was searching for someone to play Anya's mother so they could attend the interview at Eden College. He just happens to run into Yor at a boutique. Anya reads Yor's mind and finds out that she's an assassin and tries to get Loid to ask Yor to play her mother.

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.

In order to prove to Yuri that they are actually a married couple, Loid and Yor are supposed to kiss. Loid is willing to get this done immediately for the sake of Operation Strix, but Yor can't do this sober, so she ends up downing a bunch of wine and gets drunk. Yuri sees his sister this way, also gets drunk, and is unable to make rational decisions anymore...

Why has Yor been coming home late every night, her hands covered in cuts? Why has Franky asked Loid to meet him under mysterious and urgent circumstances? These are two tales of misadventure while seeking happiness in Berlint.

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?!

Yor becomes anxious about their pretend marriage after Fiona shows up. Loid notices this and thinks that Yor had started to develop romantic feelings towards him. For the sake of the mission, he flips on his Twilight mode.

Becky takes Anya to the department store so they can buy Anya some cute clothes. She uses her rich girl powers and rents out a whole shop where they start their own little fashion show.

Yor is shot in the butt while on a mission and looks miserable when she gets home. Loid mistakes her very apparent miserable mood as her being unhappy with their marriage of convenience and offers to take her out on a date.

Eden's legendary dessert finally appears! In order to obtain the macaroons that supposedly can make you into an Imperial Scholar if eaten, Anya and her friends race to get to them first.

Loid tries to pick out souvenirs that will make him look like a fun and happy dad so he can cheer Anya up. Meanwhile, Yor was facing off with Sickle-and-Chain Barnaby.

As Bond is on a walk with Loid, he has a premonition of an accident, so he tries to stop it, but is scolded by Loid. He then sees a vision of a building going up in flames and a sobbing girl standing in front of it.
