Synopsis
The Armed Detective Agency gets over their burn-out syndrome while former agency member Katai makes his debut.

Summary
As things have died down after the battle with the Guild, the Armed Detective Agency relaxes at a café on the first floor of their office building. Atsushi arrives at the café and reports they have a new job, which everyone refuses to take. The agency members are burned out after their battle with the Guild - resulting in Atsushi being famous. Noticing that Kunikida is not present with them, Atsushi asks where he is. Dazai tells him that Kunikida is eagerly working at the Agency office. Atsushi further tells them that criminal organizations have arisen to find the rumored Guild's fortune and how he encountered a Guild member the other day.

The next day, the agency members see the café ransacked, and the store manager attacked. The agency members proceed to look for the culprit. Meanwhile, the group responsible, Zapallic, is hiding in their place, boasting about their meticulous moves; not even the police can track them. After a while, the agency members manage to find their hideout thanks to Ranpo's ability and the guards taken care by Atsushi. Upon encountering the Agency, Zapallics' leader tries to call out for help, but they are refused to know they face the Agency.

After getting revenge, the manager reveals that he has employed Lucy as one of his staff members, much to Atsushi's surprise.

Kunikida and Atsushi are seen going to a broker, revealed to be a former agency member and ask for help to look at Moby Dick console. The two arrive and see Katai in a bad state and can't use his ability - revealing that he had fallen lovesick to a young woman. With this, Katai asks the two to find the woman in exchange for helping them with the console.

Meanwhile, like the Agency, the Port Mafia relaxes after the incident. Higuchi espies Akutagawa going home with a beautiful young woman one day, leaving her devastated and plotting to figure out her identity.

Higuchi is seen trying to find the woman's identity. On the other hand, Kunikida and Atsushi are also seen investigating. Atsushi senses Higuchi, and Kunikida interrogates her - but Higuchi instead learns they are also looking for the woman and politely asks them about the woman's information. While the three roam, they stumbled upon the young woman they sought.

Higuchi and Katai both give chase when they see the woman, which is revealed to be Gin, who is also Akutagawa's younger sister - much to the shock of everyone else. After the revelation, Katai still hands her a confession letter despite knowing she is a Port Mafia member. Rejected, Katai works through his heartbreak to help the Agency find their information.

Manga and Anime Differences

 * This episode has some differences from the manga regarding the Agency members' appearances throughout the plot:
 * Kunikida is present during the Agency's raid of Zapallic's hideout and helps Atsushi defeat the armed guards in the manga. However, in this episode, he does not appear when they infiltrate the gang's hideout; Atsushi overwhelms the guards on his own.
 * In the manga, Kenji is with the Agency while they are resting at the café, while he is not around when they find the place ransacked. This is reversed in the anime: he is absent during their initial rest, while he is present when they find the café in ruins.
