looks like randompasserby already got to it, it took me a while cuz i was writing stuff down in parts as i watched and then i was also helping my husband with something.
but since i went more into the explanations i'll post this anyway.
i'm NOT fluent in Japanese so i could be way off on some things, but with what i know coupled with looking up some words i didn't recognize this is what i got. better translations are always welcome by anyone who can do it.
Riho: Help me because I want to achieve number 1! She explains basically just saying the same thing, and that they're trying hard and they can get #1 with everyone's help.
Eripon: Not totally sure.. rivals are too strong?? I think about the artists that are releasing on the same day. But she wanted to re-do it because Sayu said it wasn't good and that's when everyone "ehhh"d her lol.
Sakura: Help me because I actually don't fit in with my senpai yet! She explains how generation-love is pretty strong in the group, everyone has their generation-mates so she hasn't been able to get that close to her seniors yet. Reina gives some kind words and Sayu jokes that Reina's words are deep lol. Reina says they should get along, and Sayu adds that since Reina only has 4 months before graduation they should use that time.
Haruna: I think she's saying that like Sakura she also doesn't fit in with her seniors?? And Sayu comments that she seems nervous, Haruna says she doesn't know why she's really nervous today and starts tearing up. Sayu cheers her up by reminding her of their daily #1 on Oricon. Haruna explains something I mostly don't get, but she says at some point she loves her senpai (lol, i'm useless).
Fukuchan: Help me because my back hurts from our new single "Help me!!" Sayu asks if it's because of this single's choreography. Fukuchan says yes and explains how because of her tall stature having to bend down that low is hard. Sayu asks "That's how you do it?" and Reina interjects with "Isn't that overdoing it??" lol. Fukuchan continues and explains how Ayumi is in front of her during that part and since she does it low, Fukuchan also tries to do her best at that. There's a lot of difficult things about this dance, and she practices at home too but she has gotten a lot of muscular pain on her back because of it. She jokes that she wonders if she'll be okay after this.
Ayumi: Help me because with this many fans gathered, all the way up to the top, looking up towards them is starting to hurt my neck! Response was mediocre, Sayu poked fun at the applause reaction and Ayumi apologized. This is the type of comment they're used to from her lol. But she said thanks to the fans for coming and that she'll do her best to see them all the way up there, and again the reaction was not what she was expecting and she just says "I'll stop talking" lol.
Haruka: Help me because Morning Musume's songs are too high! Reina asks if she means the key of the songs, Haruka confirms and explains how her voice is low and even in the recording of "Help me!!" her voice ended up affected. Then she asks the members if they've felt like lately the key of their songs has gone up. They agree and she says how she can barely get the notes sometimes, and she asks Tsunku if he could please think of lowering the key. Then Reina interjects with "That's no good, it should be about voice training!" lol. Haruka, "Hai!" and Sayu "Understood, Tanaka-san!", Reina replied "Do your best, Michishige-san!" lol.
Reina: Help me because the world has gone smart phone! She explains how she still has a traditional cell phone (Sayu "I know" lol), and she thinks people look really cool with smart phones but there are things she still likes about the regular type of cell phones. I couldn't understand the specifics except the part about design, but she ended saying how she wishes everyone would go back to the regular cell phones. Here Eripon interjected with "I actually have two of those type of cell phones!" to which Reina just went "ohh..." lol.
Zukki: Help me because Japan is in a bad state! Everyone is surprised by this statement and Sayu asks "How old are you again?" to which Zukki happily replies "14!" lol. Zukki explains how when she watches TV she notices the mood seems to be low (Sayu, "Japan's?" lol), and even though she's only 14 it worries her, but she'd like to use her smile as a way to lift the spirits of the country (Sayu, "Wow, your optimism is huge" lol).
Masaki: Help me because I've troubled everyone too much! Sayu says "So you knew?" (lol love this girl), but Maachan's explanation is a bit hard for me to understand. Something to do with the summer concert.. possibly for worrying people for being sick for so long? Anyway she says sorry for troubling everyone, but then she giggles and Sayu says she shouldn't laugh after apologizing lol.
Sayu: Help me because the history of Morning Musume is repeating! She explains how Yuuko was 24 in Morning Musume while the next closest to her in age was Ishiguro Aya at 19. Reina will be graduating in a few months so Sayu will be the only member left that's in her 20's, and this year she turns 24. The member closest to her in age will now be Haruna, who turns 19 this year. Morning Musume is completely molding into the way they were back in the day, but since she will be the only member in her 20's she's uneasy about that.. but if people will support her even if her endurance level suffers because she's not as young as the rest, she'll try her best!
