Kitagawa Rio’s Golden Week ‘girls trip with fellow batchmates’ photo goes viral — fans argue over who’s actually in it

The story

Idol Kitagawa Rio posted a photo on social media that she said was taken during a “girls trip with fellow batchmates” (同期, dōki — people who joined/debuted the same year) over Golden Week. Since she gave no explanation of which batchmates were actually in the shot, posters on the 5ch forum threw out three names — Suzuki Serino, Homare, and Mei — and launched into a not-quite-detective hunt for the mystery companions, poring over details like the angle of an arm and a shadowy figure in the background. Opinions split between those backing her groupmates Homare and Mei, and those backing a batchmate from an entirely different field, and the thread rolled on without ever reaching a clear conclusion.

Yeah, I'm curious which "batchmate" this is too.
Given the angle, isn't it pretty clearly Homare?
5AnonymousSep 8, 2026 20:30
I keep saying this lol
Only open the thread if you're curious about her or think she's cute lol
When people want folks like that to click in, that's when they say "just trust me and take a look"
6AnonymousSep 8, 2026 20:31
Looks like the expression she used to make a lot around Homare and Mei (fans call the pair "Homamei")

Re: #1
It's rare to see her leave the crease from her double-eyelid surgery this exposed
9AnonymousSep 8, 2026 20:31
The arm visible in the background isn't "Panda's" (apparently a nickname for someone close to her)
10AnonymousSep 8, 2026 20:32
There's another girl in the back
There's a girl taking the photo
So it's the three from the 15th class?
12AnonymousSep 8, 2026 20:34
It's probably her announcer-track batchmate (アナ→穴, forum slang for announcer)
With Homare and Mei it's probably just a group LINE chat popping up on birthdays or something, if that
13AnonymousSep 8, 2026 20:34
It should just be Homare and Mei, period — there's no "which batchmate" about it
16AnonymousSep 8, 2026 20:42
It's not just announcers — it means batchmates at TV Tokyo in general, right?
25AnonymousSep 8, 2026 20:47
Re: #16
How many TV Tokyo batchmates does she even have?
Her only announcer-track batchmate is Suzuki Serino, right?
18AnonymousSep 8, 2026 20:44
Why show off only the girls?
30AnonymousSep 8, 2026 20:49
Re: #18
It's for her jealous boyfriend's benefit
20AnonymousSep 8, 2026 20:46
That's the college batchmate who leaked her LINE messages, isn't it
Guess they made up — so sweet of Kita-chan
21AnonymousSep 8, 2026 20:46
Well, I guess
if Homare and Mei had a packed work schedule over Golden Week, then it's probably her TV Asahi batchmate
22AnonymousSep 8, 2026 20:46
Homare is impersonating Serino
23AnonymousSep 8, 2026 20:47
Do people even say "batchmate" for college lol
26AnonymousSep 8, 2026 20:48
Re: #19
It says batchmate "GIRLS"
If it were the 15th-gen group, there'd be no need to add "girls"
31AnonymousSep 8, 2026 20:49
Re: #26
Ah, I see
This might be the smoking gun
I figured Serino-chan was her only batchmate
but there must be hundreds of non-announcer TV Asahi employee batchmates, men and women both
27AnonymousSep 8, 2026 20:48
If it's TV Tokyo, there should be other female batchmates too
it's probably not limited to the announce department
28AnonymousSep 8, 2026 20:49
She's in the middle of her spring tour — can she even go on a trip during Golden Week?
33AnonymousSep 8, 2026 20:51
Rio-chan and Homare/Mei genuinely still hang out, so I thought this might be a subtle hint at that, but doesn't look like it
Reading through here, the evidence just keeps piling up
34AnonymousSep 8, 2026 20:51
There was a photo from the company entrance ceremony somewhere, right?
Weren't there something like 30 batchmates total, men and women?
35AnonymousSep 8, 2026 20:52
This girl is also a TV Tokyo batchmate

Re: #35
Huh
I figured TV show directors were seasoned pros with years of proven results, but I guess a newbie can just get handed the job straight away

You often see YouTube channels billed as "a channel launched by a former [Network] TV director" to sound impressive
but I guess that's not such a big deal after all lol
37AnonymousSep 8, 2026 20:55
Calling out how the senpai use given names for Homare and Mei but only call her "Kitagawa," or scolding people for still treating Homare and Mei like babies even after they became high schoolers
looking back on it now, it's stopped being funny
40AnonymousSep 8, 2026 20:56
Alright, girls trip
Still safe and sound, our Rio-rio
41AnonymousSep 8, 2026 20:56
And yet she said this before:

"5:00 PM was supposed to be my interview slot, but somehow Homare went first lol — I'm the busiest one here, so let me speed things up"
42AnonymousSep 8, 2026 20:57
The idol world really is messed up, making a huge fuss just because someone has a boyfriend
A female announcer having a boyfriend doesn't get her dragged like that
46AnonymousSep 8, 2026 20:59
Re: #42
Maybe she's just not popular enough for anyone to care
68AnonymousSep 8, 2026 21:25
Re: #42
Well, idols and announcers are just different, obviously
45AnonymousSep 8, 2026 20:58
Panda-san wishing Rio-chan a happy birthday made me tear up
47AnonymousSep 8, 2026 21:00
Rio-rio belongs to everyone
She's not anyone's yet
62AnonymousSep 8, 2026 21:17
The moment the previous Kitagawa thread died down, a new one popped up
was there something toward the end nobody wanted brought up?
65AnonymousSep 8, 2026 21:22
Re: #62
Skip the weird innuendo and just say it straight
66AnonymousSep 8, 2026 21:24
So does that mean down the road Rio-chan could end up on the production side at TV Tokyo, or in management, or sales, that kind of track?
I've never actually worked as a proper company employee myself, so I'm just guessing based on stuff my customers, friends, and family with real corporate jobs have said lol

Re: #66
Are you the guy who's always starting threads about Aoi and Getter?

Background and Key Points of This Discussion

In the idol world, the exact line-up of “batchmates” — members who debuted or joined the same year — tends to become a hot topic every time someone posts on social media. Because batchmates often appear together, fans piecing together who’s in a photo from details like poses and half-remembered past interactions is a familiar ritual on Hello! Project-related forums. This time opinions split because posters didn’t agree on what “batchmate” even meant in this context: some backed her in-group batchmates Homare and Mei, while others backed a batchmate from an entirely different field, like Suzuki Serino. Since Kitagawa herself hasn’t clarified anything, neither side has moved past speculation. The thread also touched on friendship troubles and celebrity dating rumors, but those comments were based on individual posters’ memories or hearsay, not confirmed fact. Readers should keep in mind that the identity of the person in the photo remains unconfirmed, and the surrounding anecdotes are unverified.

※This article is excerpted and summarized from the 5ch (Hello! Project) thread “Unbearably cute Kitagawa Rio-chan: “A photo taken during a girls trip with batchmates over Golden Week 📷” — which batchmate is this? Serino-chan? Homare? Mei?“.
