Twilight, codinome do melhor agente de espionagem de Westalis, recebe sua nova missão: fazer seu filho entrar no prestigioso Colégio Éden para se aproximar de Donovan Desmond, do Partido da União Nacional. Primeira meta: obter um filho.

Yor Briar é uma funcionária pública na prefeitura de Berlint e, ocasionalmente, assassina profissional. Recentemente, várias mulheres solteiras se aproximando dos 30 anos estão sendo denunciadas como espiãs, então, para tranquilizar seu irmão, Yor diz que está namorando.

Yor se muda para a casa de Loid e Anya, e o disfarce de família está completo. Agora Loid começa a preparar as duas para a entrevista, mas nem a Anya ou Yor parecem prontas para a etapa seguinte da missão...

Finalmente chega o dia da entrevista no Colégio Éden e os Forger entram nos terrenos da instituição. Porém, o processo de seleção começa antes mesmo da entrevista, com a avaliação do comportamento das famílias ao longo do caminho!

Chega o dia do Colégio Éden anunciar a lista de aprovados e Anya... não passou. Pelo menos não na primeira chamada, mas, com muita elegância, o professor Henderson informa a família que ela é a primeira na lista de espera.

O primeiro dia de aula no Colégio Éden se aproxima e os Forger vão comprar o uniforme, que fica pronto em poucos dias. Porém, por ser um colégio de elite, alunos uniformizados acabam se tornando um alvo fácil para bandidos.

Depois do fiasco do primeiro dia na escola, finalmente começam as aulas no Colégio Éden, mas Anya já tem fama de delinquente. Felizmente Becky fica ao lado da amiga, só que isso também faz com que seja difícil para Anya pedir desculpas a Damian...

Depois de um funcionário da prefeitura ter sido detido pelo Serviço de Segurança do Estado, ele é interrogado pelos melhores membros da polícia secreta, incluindo Yuri, irmão de Yor... que está muito bravo por não ter ouvido sobre o casamento dela durante um ano inteiro!

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...

Se você consegue desviar de um raio, consegue desviar da bola. Na próxima aula de Educação Física da turma da Anya, eles enfrentarão a turma 4 em um jogo de queimada e, dizem as más línguas, que o melhor jogador da equipe vencedora leva uma tão cobiçada Estrela.

In order for parents to attend one of the social gatherings at Eden College, their children need to be Imperial Scholars, but Anya hating to study makes this rather difficult. Loid then comes up with a plan to get Anya to get Stella Stars by doing community service rather than with her academics. But when she ends up volunteering at a hospital, she continuously messes up. Later, she hears a child drowning in a pool with her telepathy and...

Loid is burdened with one mission after another from WISE and comes home exhausted. He then hears neighbors gossiping that he's neglecting his family. Because he can't let anyone doubt them as a family for the sake of Operation Strix, he decides to take his family to the aquarium the next day they have off to show everyone that they get along. However, he is assigned another mission from WISE while he's there, and...

The Forgers go look for a dog for Anya's reward for getting a Stella. In the middle of their outing, Loid ends up having to work a mission to stop a terrorist bombing attack planned against Westalis's foreign minister. Meanwhile, Anya is trying to pick out a dog, but then sees a vision of her family when she randomly reads the mind of a giant, mysterious, white dog. Anya becomes curious and chases after the dog, but she ends up accidentally wandering into the hideout of the terrorists!

Anya meets a mysterious dog who can see into the future. They were able to escape from the terrorists with the dog's help, but eventually, they fall back into the hands of the terrorists again. And then Yor shows up and attacks the enemy! Soon after, the dog sees into the future again. The vision Anya saw through the dog's mind was Loid unconscious and buried under the remains of a building that had been bombed. In order to stop this future from happening, Anya and the dog head to the place where the incident happens!

Loid faces off with one of the enemy's bomb dogs, Anya secretly saves Loid, and Yor finds the leader of the terrorists who had been on the run. The whole family ends up involved in this terrorist bombing incident, but what will be its conclusion?! Also, they were supposed to go get a dog for Anya as a reward for her getting a Stella, but now, she says she wants to keep the mysterious, giant dog that she encounters in this incident. Loid knows the truth about this dog as well as the other dogs involved in the bombing incident and tells her no, but then Anya says she'll quit going to school if she can't have the dog and...

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 and the rest of her class have an arts and crafts lesson where Anya is put in the same group as Damian. Sylvia goes about an ordinary work day. We learn the secret source of Yuri's strength.

Next week is Eden College's midterms. That week happens to include the new moon, the one day of the month Anya can't use her powers to cheat. But then, Yor suggests that Yuri should be her tutor...

The midterms are over. Loid is nervous about Anya's test scores and heads to Eden College to alter the answers. However, there already seems to be another guy there with the same motive that's making himself insanely suspicious and obvious?!

Damian does well on his midterms, so he earns a Stella. Everyone around him is now praising him, but for some reason, his classmate George seems to be looking at him begrudgingly. The reason being...

After seeing Anya off to school, Yor finds Anya's gym clothes on top of her desk. At this rate, Anya will surely have trouble in her gym class. Yor runs to deliver the forgotten clothes!

Fiona, who works at Loid's hospital, happens to actually be the female WISE agent Nightfall. She is irritated that Operation Strix is facing delays, so she suggests that she becomes Mrs. Forger instead. She also decides to show up at the Forger household unannounced and comes face to face with Yor!

Anya loves the penguin plushie that Loid got for her, and even sleeps with it. However, a pale shadow shoots jealous glares in the penguin's general direction...

The secret files called the Zacharis Dossier may cause a war between the East and the West. In order to obtain a painting that is supposed to be the hiding spot for these files, Loid and Fiona enter an underground tennis tournament run by the owner of the painting, Campbell. If they win, the art piece they're after will be presented. Loid and Fiona enter as a married couple and play various skilled players including pro players!

The underground tennis tournament is finally heading to the final match. The Campbell siblings that Loid and Fiona are up against are playing dirty, as they have altered tennis rackets as well as the staff helping them out. But the spy pair from WISE overcome one obstacle after another and Loid deals the final blow! But right after the match, the State Security Service finds out about the dossier and infiltrates the tournament...

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.

A social gathering happens at Eden College once every half term. It is a strictly guarded event where only Imperial Scholars and their parents, the VIPs of Ostania, are allowed to go. Damian tells his brother that he'd like to see their father when he attends the event. Loid finds out about that and uses Damian to get close to his target.
