Plot

edit

Mimei and Kurage listen regularly to the weekly late-night radio show Monday Midnight Talking (Mon-Mid), which features the hosts The Long Hopes, a manzai duo consisting of Osera and Koyama, reading jokes submitted by listeners on air. Mimei, who succeeds at nearly everything he tries, has never had a joke read on air, and idolizes an amateur comic who uses the pen name "Eel Potato" and has a submission read nearly every week. After his friend Kurage confesses to being "Eel Potato", she adds that she will not date anyone who is less funny than her. Is his renewed motivation (and her encouragement) to have his submissions read on-air born out of his frustration, her sense of competition, or from genuine romantic interest?

  3. "After All, I'm a Rival" (ライバルだから, Raibarudakara)
Mimei is shocked to learn his friend and fellow Mon-Mid fan Kurage is the famed on-air contributor "Eel Potato". She advises him to send in multiple submissions, and his joke is read on-air for the first time. They aim to enter the Listener Kōshien, despite her huge lead. To research the week's prompt, Kurage invites Mimei to karaoke; once again, her submission makes it to air. Because Mimei realizes he needs experience to write better jokes, Kurage takes Mimei to a cafe run by her friend, Natsu Akabane ("Bat Bahtz-Waru"), who promptly puts both to work. Mimei and Kurage shop for radios with their cafe wages and pick a matching set. Later, one of his jokes is read on air, while hers is not. For the Ball Game Festival at school, Mimei competes in soccer and Kurage is drafted onto the basketball team. When he sees her practicing alone, he teaches her while they listen to an old Mon-Mid episode which had three entries read on-air from Eel Potato. To their surprise, the next prompt involves basketball. Kurage's friends ask if she is dating Mimei; he overhears and wonders how he feels. After running into each other at the convenience store, Kurage asks if he has started to hate Mon-Mid, but his glum attitude is from missing out on collaborative merchandise. They visit Natsu together, who gives them some of the sold-out merchandise, and later that night, congratulate each other, as they each had one joke read on-air.

Shuri Ebina, aka "Shrimp Sushi", another Mon-Mid fan, confronts Kurage, but she does not react until Shuri calls Mimei "some random listener". The trio research that week's prompt at an arcade and form an awkward friendship. After Kurage tells Mimei that he can't be funny by being a good kid all the time, they run to the fifth anniversary Mon-Mid event through the rain, which wrinkles their stickers; Kurage does not regret the memories. The Long Hopes mention them on-air as a soaked high school couple they passed who were obviously having fun; Mimei fears Kurage is acting strange because of that call-out, but she is suffering from a cold. He takes her to the nurse's office and walks her home after school. Kurage passes a makeup quiz in math using his mechanical pencil, which she claims absorbed his diligence, so in exchange, she gives Mimei her joke writing pen. Mimei and Kurage submit jokes with postcards due to phone issues; Kurage's joke is read and Mimei's thanks are shared privately among the Mon-Mid staff, who notice the postcards came from the same neighborhood. Kurage and Mimei return to Natsu's cafe and buy a disposable camera to research the latest topic; Natsu asks Mimei to photograph Kurage while they find the Mon-Mid mascot Midran at the neighboring shopping mall. Kurage takes a picture of Mimei for the last frame. With only four points, Mimei fails to qualify for the Listener Kōshien. After school, they run into Shuri, who drops her Line contact information and an Omamori amulet, inspiring Kurage to visit the same shrine, where Mimei prays for her success, receiving "small luck". She prays that he will join her in the next competition next time and pulls "expected person", auguring well. For the Listener Kōshien semi-final, ten contestants each submit ten entries and the three with the most read on-air advance to the finals. Kurage, buoyed by Mimei's cheering, gets one more than Shuri, advancing to the final with "Hateful Eight" and last year's winner, "Battle Chimney". Kurage asks Mimei to listen to the finals together; when he is surprised she is being shut out, he hurries over to encourage her.

  4. "What Do You Think?" (どう思ってる?, Dō Omotteru?)
Although she staged a remarkable comeback, Kurage finishes second to "Battle Chimney". She calmly asks Mimei to push her on the swings, where he initially does not see her crying and when he does, he comforts her by offering some tissues. He vows to compete as her peer, and the next day, she says the next Listener Koshien has started. Mimei picks up some products used by the Long Hopes; at school, he panics when he sees Kurage has matching items, fearing he is being too forward; she says she noticed and wants more matching things. To research the next prompt, Kurage studies "all-too-perfect" Mimei as he goes through a typical day, admiring his perspicacity. They each have an entry read that night on Mon-Mid. Mimei researches a prompt for his friend Nakatani by shopping for a present for a girl. At the mall, he runs into Kurage, who invites him to a meetup for Mon-Mid Listener Koshien contestants. Kurage misses the start of the meetup to make up a math test; in her absence, Mimei's awkwardness evaporates after introducing himself as "Eel Potato"'s disciple. After Kurage shows up late, Mimei runs an errand for Natsu. Outside, he meets "Hateful Eight", a professional comedian who describes himself as "not funny at all", recognizing the same characteristics in Mimei and encouraging him to keep working to beat "Eel Potato". Walking home together, Kurage tells Mimei that right now she is the only one who knows how funny he is. Mimei hits a submission slump as the summer school break starts; walking home, they duck into a Saizeriya restaurant for lunch to wait out a sudden rainstorm. After their meal, they are stunned by a vivid rainbow and Mimei nervously proposes weekly listening meetings together, to which Kurage readily agrees. The next week, they attend the Tozai Radio Festival and run into a fellow Mon-Mid Listener Koshien contestant Torano Karino, who is running an event using Midran, the Mon-Mid mascot, to sell a new drink. Kurage steps in to portray Chef Midran. She slips coming off the stage, but Mimei catches her by the hands; is her face flushed only from the heat of the costume? Torano assumes that Kurage is Mimei's girlfriend, which he quickly denies. As research for the next topic, Mimei asks Kurage to visit a summer festival together, then frets he is being too forward. When he arrives, wearing a yukata, she is already working at Natsu's yakisoba stall alongside Natsu's grandpa. Natsu loans Kurage an old yukata and Mimei proves to be an able paper net fisherman while Kurage's efforts go awry. When they try to watch the fireworks with Natsu, they are separated by the crowd.

Reception

edit

Kittun Nozomi of Real Sound [ja] felt that the comedy was more relaxed than Akane-banashi and Beshari-Gurashi, two other comedy manga published in Weekly Shōnen Jump. They also liked the focus on the late-night radio subculture and the story's setting.[8] Radio personality Hikaru Ijūin discussed the manga during an episode of his show.[9]

The pre-orders for the first volume sold out on Amazon Japan.[3] By May 2026, the series had 300,000 copies in circulation.[10]
