•The program starts with
this.•HARU says that the remaining five mistakes might be a little harder to discern. TOMO then asks about staff member Kawai-chan presumably holding an acoustic guitar (RINA: "They look like a singer-songwriter"). HARU says that they'll continue the program while some background music plays. The others are confused, and TOMO goes, "Wait, wait, wait. I don't understand! What kind of reply is that?!" HARU laughs and Kawai-chan starts playing the guitar. TOMO goes, "That's so scary!" The three of them are confused at what's going on. HARU then says that six mistakes have been found. The others are confused again and RINA asks what the most recent mistake was. HARU says that the staff member playing guitar as their BGM, as they normally do not do this, is one of the mistakes.
•MAMI then asks HARU if there are any other mistakes that can be seen in plain view, which she says yes to. TOMO guesses that their program director now has 22 cups, which is wrong. They continue looking around before HARU and TOMO say that they should start reading some messages. HARU does reconfirm that there are things in plain view. MAMI goes, "Ah, our chairs are different!" HARU laughs and says that they're the same as before. RINA says that their chairs were always all different to begin with. HARU says that there are two mistakes that can be seen, and also says that they did the Kinoko no Yama thing a while ago but no one noticed. They're still confused and MAMI says that she doesn't know what they could be at all. HARU then gives them a hint that it's near their program staff members. After a few seconds, TOMO notices something about one of the computers, which then makes them break out into laughter. They go, "What's with that?! It's sooo small!" The "ding dong" sound plays and HARU confirms that it's a toy Macbook Air. RINA says that she didn't notice that before.
•They continue looking for more mistakes, which HARU and the staff laugh at. She gives them another hint that it's around their program writer Ono-san, who then tells the band to list their New Year's resolutions. HARU asks RINA to go first. RINA pauses and says she doesn't have any at all, which HARU and the staff laugh at. RINA says that this year is the band's 15th anniversary and the year that RINA will turn 30. Since she'll have been in the band half of her life so far, she wants to cherish both music and her life. HARU says that you start to think about things like that when you turn 30. RINA wonders if that's true, and that it's something she hasn't thought about until recently, and that she wants to have more fun things happen.
•HARU suddenly asks if MAMI's doing okay, which the staff laughs at, since she's still looking for what the remaining mistakes could be. HARU says that they might be hard to get. TOMO guesses that Ono-san is wearing an unfamiliar ring, which is wrong. MAMI mentions something about a white piece of paper, which makes HARU go, "Ah!" MAMI seemingly looks closer and wonders if one of the staff members lost their script. RINA says that it's blank, which is the right answer.
•There are now two mistakes remaining. HARU says that they may have already noticed one of them, and that the last one is pretty hard to spot. TOMO asks if it's something they've touched. HARU says no, but they should have already seen it. They wonder what it is for a little bit until HARU asks MAMI to say her resolutions. MAMI goes, "Eh? Resolutions? Resolutions...... What should I do in 2021...... Eh, I'm kind of unsure." HARU and the staff laugh at this. MAMI then says that she's kind of thought about it and then pauses for a long time again. They laugh again and RINA brings up the mistakes, asking if it has to do with a lot of packages that were brought in to where they're recording. HARU says that's not quite it, but that that's a good observation. They then wonder if someone's in disguise. RINA asks if it's someone they know, which HARU says yes to. She then says to remember back to
the first championships. MAMI asks if she's talking about how there was different person (Yamada-chan, a woman) doing audio for the episode instead of their usual person (Kawai-chan, also a woman). HARU goes, "And...?" MAMI is confused and says that Kawai-chan is here for the recording today. HARU goes, "Instead of Kawai-chan was...? Who was that person?" MAMI says that Yamada-chan was the person who brought in all of the packages today, which HARU says is correct: Yamada-chan works for a
takkyubin service. The others are surprised. MAMI says she didn't see her and RINA says that she had no idea at all. HARU says that she thought the others had seen her, which is why she gave the hint that she did. When they're recording Catch up, it's usually that a delivery man comes to deliver packages. Since Yamada-chan is a woman, they considered it a "basic mistake." The others say that was difficult.
•They go back to MAMI's resolutions, which she's still unsure about. HARU says there is one more mistake remaining but they're most likely not going to figure it out, so MAMI should focus on deciding what her resolutions are. She still doesn't know what to go with. The others say they can be anything. She finally decides that, as she love to make her own clothes and buys a lot of fabric for that, she will organize her fabrics. The others chuckle and HARU asks how many she's bought. MAMI says she's bought a ton. HARU asks if she's collecting them, and MAMI says that she often buys 2-3 meters of fabric at a time, so she has a huge pile of them.
•HARU then asks TOMO about her resolutions. TOMO says that she grew a vegetable garden on her balcony during the stay-at-home period last year but it didn't work out since the weather was too rainy. She basically could only grow one cucumber and a few strawberries, so she'd like to try doing it again this year and hopes that the weather's more stable.
•They then return to the last mistake. MAMI asks if it has something to do with Ono-san, which HARU says yes to. RINA thinks that it has something to do with the script. MAMI says that she doesn't see one. HARU says that they're close, and that you can see it if you change your viewpoint. TOMO says that there are loose threads [on Ono-san's clothing, presumably], which isn't correct. RINA says that they give up. HARU says that she'll then announce what it is. The correct answer is that Ono-san mistakenly brought soy sauce instead of coffee. The others say that they had no idea. MAMI says that she did notice that he wasn't drinking anything. HARU says that Ono-san often makes mistakes in the script too. They look at it and TOMO says that it says "Catch uppy." HARU says that it actually says "Cutch uppy." RINA asks if he actually made that mistake, which he says he did.
•The staff asks HARU what her resolutions are. She says that she's been drinking miso soup once a day for a bit now to improve her constitution. She used to eat bread for breakfast, but now she drinks miso soup instead. She adds in things like wakame (seaweed), mushrooms, and tofu. She'd like to try continuing doing this for as long as possible. She says that this alone helps to change her body, which the staff asks her in what way it changes it. She says a lot of stuff that I'm not going to list lol but basically, it's good for capillaries and your body feeling lighter overall.
•As they close out the episode, they say that since they already had this championship during the first episode of 2021, that means that this relaxing and peaceful atmosphere will continue, since that's how Ono-san does things. MAMI asks if that means that they're not going to do any recordings on-location, which HARU says yes to. RINA and TOMO both go, "What's with that?!" at the same time. They both say how doing those were pretty fun and that they were really looking forward to doing more. HARU says that they originally planned for that but can't do so anymore, but above all, the staff is enjoying this program, which the staff laughs at.
