Azuki Masaoka and Matcha Kobayashi, the main characters from SEGA’s Utagumi 575, have been released as VOCALOID4 libraries.
I thought they would attract more attention, but are there actually many people who haven’t noticed?
Here are the reasons why Azuki and Matcha deserve the spotlight.

What is Utakumi 575?
Utagumi 575 is a SEGA game released for the PS Vita.
There was also a smartphone app game called Uta-Yomi 575, but its service ended rather quickly.
Branded as Project 575 and even expanded into a short anime, but the results were far from successful, to say the least.
One of the game’s features was that you could apply any lyrics you liked to songs provided by Vocaloid producers (Vocalo-P), and the built-in Vocaloid engine would sing them.
Simply put, it was a parody song, but I think it was good practice for writing serious lyrics, and it was probably helpful for people who want to participate as lyricists to practice as well.
It didn't work... (sweat).
The smartphone version was a game like this—I actually liked it quite a bit.
The design has been revamped, giving it a slightly idol-like vibe.

The left is red bean, and the right is matcha.
The two main cast members are Azuki Masaoka, a mischievous hotshot, and Matcha Kobayashi, who’s cool but a bit out of touch.
She wore a uniform in Project 575, but her outfit changes in the package illustration.
It ended up looking quite cute.
Compared to a uniform, it feels more like an idol style.
I hope this will be the trigger that increases its visibility.
The cast is really star-studded.
In Project575, there is also a character named Yuzu Yosano.
Who is the voice actress for Yosano Yuzu-chan?Minako KotobukiYour famous role is Tsumugi Kotobuki from K-On!, right?
Of course, the main cast members Azuki and Matcha were also portrayed by popular, highly skilled voice actors.
Azuki beans areYuka OtsuboMr./Ms., matcha is Hegochin (Hekochin).Ayaka OhashiI am Mr./Ms. ____.
In recent works, Ayaka Ohashi has played Saaya Yamabuki, the drummer of the protagonist band in BanG Dream!, and she also performs as a drummer herself on stage at BanG Dream! live shows.
Yuka Ōtsubo and Ayaka Ōhashi have also appeared together in The IDOLM@STER Cinderella Girls.
They had co-starred, with Ms. Otsubo as Kanako Mimura and Ms. Ohashi as Uzuki Shimamura.
This isn’t an ordinary matter, you know?
Uzuki and Kanako will sing for us!
For now, let’s listen to the official preview audio.

And Shimamura Uzuki, too.

How does that sound?
I feel like we can get pretty far with this.
In other words, if you work hard, you can get Kanako Mimura or Uzuki Shimamura to sing your favorite songs!
Wouldn't Producer-san be unable to just silently see them off?
If the passionate energy of the powerhouse, high-momentum Idolmaster community were poured into it as a series, I feel like it could turn into something pretty incredible.
Being noticed is important in anything.
Azuki and Matcha are set to debut as VOCALOID4 libraries, and there’s a strong possibility that their popularity will rise thanks to the attention drawn by their voice providers.
I think there are probably many people who didn’t know about 575 or anything like that, but if you tell them that Uzuki has become a VOCALOID, wouldn’t some of them perk up with interest?
That’s exactly why 5-7-5 is such a real shame… (tears).
You never know what might spark you to start—this could be the push for someone to try buying a library and maybe even have it sing a little.
Maybe, with just that kind of spark and passion, someone might emerge who creates an amazing work.
Being noticed in any field and attracting people become powerful driving forces for new breakthroughs.
These days, you sometimes see veterans driving away newcomers by calling it the end of the boom or a dead trend, but maybe a wave of momentum is coming that will let us laugh those words off.
As both a 575 player and a Hegochin fan, this was information I couldn’t really overlook, so I put together a summary.
Can Azuki and matcha bring about the biggest breakthrough since Hatsune Miku?
If you’re thinking about getting into Vocaloid or you’re a producer in charge, this might be the moment to spend some money!
