Ren is on the prowl for proof of Naosuke’s deception, and the Hubby spy is on the prowl for keys of all kinds! How will the gang navigate these two crises?

As the Hubby attacks escalate, Shoin decides his presence on the scene is required. Meanwhile, a breaking news report leaves Teruko with doubts about her choices.

Shoin's appearance causes a big fuss among all the residents of Astro Lodge, except Ren, who is more worried about his field trip.

Takumi and Aoi head to the Insect Festival, only to be roped into an unexpected event supposedly involving the key Mira's looking for.

Takumi reports to his job interview venue, expecting it to be a fancy restaurant. What he finds there, however, is a rundown share house and its wacky inhabitants.

Takumi tries to make sense of what he heard Mira say, but his efforts to figure it out only make the confusion worse. Meanwhile, Astro Lodge gets a pair of mysterious visitors.

Takumi hatches a plan to catch the breakfast thief, only to fish up more than he bargained for!

The gang finally finds a lead to the key! At the same time, it also means Mira’s departure is getting closer. How will Takumi and the other Astro Lodge residents react to the news?

The letter from Mira's mother tells all about her connection with Shimotakaido Tasuke, which leads the gang to try to learn more about him in earnest.

Takumi has no idea how to interact with Aoi after her outburst, and the Wakabayashi family have a falling-out.

Inspired by everyone's hard work, Yu makes a commitment to pursue her dream with equal vigor.

Takumi can't get over the shock of what he saw, while Tomihiro has concerns about the magazine Ren's hiding from him.
