At the meeting, he finds out that Anya will have to receive 8 Stellar Stars and become an Imperial Scholar at Eden College in order for him to successfully complete Operation Strix. Meanwhile, Anya is very excited about getting her new uniform. But there are...

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...

A rumor spreads amongst the first graders at Eden College saying that if they do well in their next PE class, they will get rewarded with Stella Stars. Anya is determined to get a Stella Star, so she trains with Yor. Thus begins the dodgeball match between Cecile Hall and Wald Hall! Anya and her classmates are determined to win, but they are faced with the giant, Bill Watkins.

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...

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...

The Forgers plan to reward Anya for getting a Stella by adopting a dog, but Loid ends up working a mission to stop a terrorist attack. Meanwhile, Anya encounters a mysterious dog and accidentally wanders into the hideout of the terrorists!

Anya meets a mysterious dog who can see the future. They almost escape from the terrorists when Yor shows up and attacks the enemy! The dog sees Loid will be injured in the terrorist attack, so Anya and the dog head out to stop the bombing!

Loid faces off with one of the enemy's bomb dogs, Anya 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?!

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.

Eden College's midterms will be on the new moon, the day of the month Anya can't use her powers to cheat. Then, Yor suggests that Yuri should be her tutor. After the midterms, Loid gets nervous about Anya's scores and decides to intervene.

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.

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 is out of sight, Anya starts to explore!

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.

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.

The underground tennis tournament is finally heading to the final match. The Campbell siblings that Loid and Fiona are up against are playing dirty, but the pair from WISE overcome one obstacle after another, and Loid deals the final blow!

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