**UPDATE ON SEPTEMBER 14, 2019**
Project SEKAI’s official Twitter has started what they call #セカイのウワサ (SEKAI no uwasa, or “rumors about SEKAI”) tweets in which they reveal bits of information about the game.
The first of such tweets announces the game’s genre as “rhythm and adventure,” featuring a brand new rhythm game system that will offer a whole different experience from the Project DIVA series! They also tease that there may be more parts to the gameplay that will be revealed later on.
**UPDATE ON SEPTEMBER 20, 2019**
The next rumor tweet states that not only will Project SEKAI include many familiar songs from the Project DIVA series, but also new and up-and-coming songs, including at least 10 brand new ones made for the game!
**UPDATE ON September 24, 2019**
The next rumor hints that all six piapro characters – Hatsune Miku, Kagamine Rin, Kagamine Len, Megurine Luka, MEIKO, and KAITO – will be in Project SEKAI.
**UPDATE ON SEPTEMBER 27, 2019**
Another teaser mentions that the individual responsible for spreading the rumors about SEKAI will finally be making an appearance in October, and shows who appears to be a MEIKO kigurumi (MEIKOdayo?) meeting and shaking hands with 近藤P / KondoP of Famitsu. Since it is almost October, we won’t have to wait long to learn their identity!
Furthermore, Wataru Sasaki of Crypton Future Media tweeted that SEGA is planning two different projects with MEIKO in celebration of her upcoming 15th anniversary on November 5, 2019. This will likely be part of the October announcement, so look forward to more news on this!
**UPDATE ON SEPTEMBER 30, 2019**
Back to the rumors about SEKAI, the next one reveals that the game will be using brand new models of the piapro characters that are optimized for the mobile platform. A sneak peak at the model for Miku was even shown!
**UPDATE ON OCTOBER 5, 2019**
The latest rumor reveals that the story of Project SEKAI is actually set in our world, modern-day Japan to be exact! And just like our world, Hatsune Miku and her friends exist as virtual idols.
Howoever, their world, the mysterious “SEKAI,” has one important difference from ours. What do you suppose it could be?
**UPDATE ON OCTOBER 11, 2019**
The latest rumors about SEKAI reveals that the “sekai” worlds are actually created from the thoughts and feelings of people in the real world, and are as numerable as we can imagine up. Furthermore, in each “sekai,” there exists its own version of Miku.
**UPDATED ON OCTOBER 15, 2019**
Today’s rumor reveals that it’s not just the silhouetted girl in the teaser image, but a whole cast of original characters who will be making their debut in Project SEKAI! Furthermore, each one is part of a music unit with their own unique music style, and Miku could be singing and performing with all of them!
**UPDATE ON OCTOBER 22, 2019**
The newest rumors about SEKAI states that the featured songs in the game can be played and enjoyed in two different ways:
1) The original VOCALOID-only version
2) New “sekai” versions of the songs that are sung by both the VOCALOIDs and the game’s own original characters!
As more about the game is revealed, we’ll report on it!
