#i read on twitter that when Yukkii was cast as Shiho she apparently wasn't even shown a character design because there wasn't a finished on

[project-sekai-facts]

Since you uploaded that MMJ Miku beta design, do you know if there are other beta designs of the characters?? I'm curious since there's a little bit of concept art of project sekai.

Ah well project sekai featured in this one issue of a Japanese magazine called CG WORLD which is where I got that art from. That magazine is more focused on the costume designs though but it does have some concept art, but aside from WIP costume designs using the final character designs, all of it is blurred out unfortunately.

You can find some WxS beta designs, a Shiho beta design and some low quality MMJ beta designs out there (not entirely sure how people found these, I think they were left in a beta release and got datamined), but that’s all the unblurred stuff you can find.

And there are no VBS beta designs available. There’s some WIP costumes for Akito, Kohane, Miku and MEIKO (i posted her one ages ago), but there’s no actual concept art of them available anywhere.

I can go through what we do have though because they’re probably too low quality for me to post as an actual fact.

So these three images were in the CG WORLD magazine. You can tell who the members of Leo/need are based on the instruments (L->R: Saki, Honami, Ichika, Shiho, Miku), and MORE MORE JUMP! (L->R: Miku, Haruka, Airi, Minori, Shizuku) isn’t too different from the final designs aside from Shizuku, who’s blonde (probably because Shiho is). Niigo is harder to identify outside of Kanade and Miku. This art was also uploaded on TCRF and whoever put it there said that Mizuki is the brunette, Mafuyu is the one sitting next to Kanade and Ena is the one in the purple cardigan. It's not stated who is who in the magazine.

And here’s some actual beta assets. You’ve got WxS and Miku (there's two people in the back) here. Emu didn’t really change much aside from the eyes, but other than her...? (I edited this since it was posted don't mind the change)

We have the leader, who is literally just a palette swap of Rui's initial 2* with Tsukasa's face (excl the eye color which was given to Rui) and hairstyle. Possibly Tsukasa bc leader, possibly Rui bc design, possibly a scrapped character who was split in two

There's someone in the back behind leader boy and blonde girl wearing a pink-purple shirt and white jacket with a yellow tie. Clearly their color palette was used on Rui later down the line. Other than that there's nothing we can tell about this character, not even their gender. Possibly Rui, possibly Miku, possibly a third character who was scrapped/reworked

We have blonde girl, who's hair color and eyes seem to have been reused for final Tsukasa. Usually this is assumed to be Nene due to not resembling any finalised designs for the most part. I think she was probably scrapped, or heavily reworked and became Nene with some design elements passed onto Tsukasa (or Tsukasa was a girl?)

And in the back behind Emu is a girl in a green blazer and grey skirt that looks like a school uniform. Maybe this is Miku because the costume doesn't really match with the others? She doesn't have pigtails though, but no one here has pigtails. There's literally nothing identifiable about her.

Whoever these people are there were clearly a lot of changes made to WxS and these might not even be Nene/Rui/Tsukasa. That's definitely Emu though.

And here's a gacha bg and live bg demo for MMJ. The screen on the first image seems to be displaying a less-blurred version of their concept art. For the record, the illustrations in the second screenshot are from idolm@ster, they are not MMJ concept designs, but part of Shizuku can be seen to the right of the pink haired girl.

Possibly might've been named RE:START given the neon lights in the second image. Has some backing: their first event was called RE:START from Here!, and NaytalieN said in an interview that there was extremely little development on MMJ outside of character illustrations when he was commissioned for that event (and a couple statements imply the game was still in fairly early development too). Or it might've just been a catchphrase for the group or something.

And this. High quality beta-Shiho. This was used as a placeholder card art (surprisingly finished for a placeholder) for MMJ!Miku’s initial card, which by the way, looks exactly the same as the final version only it hasn't been finished yet. I’m pretty sure this is Shiho and not Shizuku because of the side ponytail and image color. But Miku is wearing a similar costume to the one in the MMJ concept art. I mean it was marked as placeholder and was not intended for use, it doesn’t really have to make sense. Also what seems to be a costume for Miku based on this card was left in the game and is on TCRF I added the screenshot below.

I haven't finished translating the CG WORLD article yet, but there's not a huge amount dedicated to character design, as I said earlier it's mainly about costumes. What I can tell you though is that VBS and WxS apparently took longest to finalise, specifically Akito and Tsukasa.
