Project SEKAI: Colorful Stage![a] is a video game developed by Colorful Palette and published by Sega. The game is a spin-off from Sega's Hatsune Miku: Project DIVA series, featuring the 6 Virtual Singers of Crypton Future Media, Hatsune Miku, Megurine Luka, Kagamine Rin and Len, MEIKO, and KAITO, alongside the cast of 20 original human characters that are split into five themed units. Set in the real world where Virtual Singers only exist as fiction, the characters come across another dimension called "SEKAI," where various "true feelings" are projected.

The game was released for Android and iOS devices on September 30, 2020. Sega released an English server of the game worldwide on December 7, 2021, with expansion to 5 countries in Southeast Asia on September 25, 2023.[1][2][3] A Taiwanese server, published by Ariel Network, was released on September 30, 2021.[4][5] A Korean server was released on May 20, 2022, in South Korea, published by Nuverse.[6]

Gameplay

[edit]
Example of gameplay of Project SEKAI: Colorful Stage!. The track being played in the background is "Otome Dissection" by DECO*27.

Project SEKAI: Colorful Stage!'s gameplay consists of tapping notes as they slide toward the bottom to the rhythm of a chosen song; players have to tap, slide and flick to match new free-form rhythm notes, and special yellow notes that are worth more points towards the score. The overall gameplay is similar to Sega's Persona Dancing (Atlus), Chunithm and Bandai Namco's The Idolmaster-themed rhythm games, the players are given 1,000 health points to clear a song with the ability to heal through character skills, and one can adjust song speed and difficulty to their liking. In lieu of an energy system that is prevalent in most free-to-play games, this game utilizes Live Boosts that increases rewards for completing a song, and players can continue playing even when they run out of boosts.

Players gain experience points (EXP) by clearing songs and listening to overworld conversations between characters. Such conversations are fully voiced with 2.5D movement via Live2D technology, and their conversations are depicted in a visual novel-style presentation that is prepared for each group, including the Virtual Singers such as Miku. Further conversations are added over time through events. EXP also improves a unit's rank, which unlocks additional chapters in group stories. Cards, which use a star ranking system to determine rarity (four stars being the rarest), are acquired via the gacha system, a luck-based mechanic in which players spend the in-game currency Crystals with the hope of winning their desired cards. Although this is a free-to-play game, players can spend real-life currency to acquire in-game currency.

The game also features Virtual Lives, which is a mode where players can go to a virtual concert, similar to augmented reality (AR) or a Vocaloid live concert, where players can interact with one another. They can see other players all around the world and their favorite group performing via 3D animation.

The game initially launched with 28 songs, with around four new songs added per month to the game; As of May 2024, a total of 429 songs are included. The tracklist mainly consists of Vocaloid songs or those from Vocaloid producers, with most songs having two versions: the original version (or new versions specifically made for the game; named "Virtual Singer version" in-game), and SEKAI versions, having the song covered by the original characters, and sometimes joined by a Virtual Singer. Some songs also have a 3D MV or animated MV, with animated MVs either being newly created for the game (named "2D MV" in-game) or original. Songs without an MV are played with a static 2D background, known as "Lite" in game.

Plot

[edit]

Setting

[edit]

Project SEKAI : Colorful Stage is set in the real world, specifically in Shibuya, Tokyo. In this game, Hatsune Miku and her friends are famous fictional singers existing in the real world as Virtual Singers. They sing songs from creators all over the world, but they also exist in "SEKAI" (セカイ), a mysterious world different from the real world that is created from a person's "true feelings", featuring various visual appearances based on the person. There are as many SEKAI as there are emotions, and its form changes depending on the person's emotions. Therefore, the focus of the game is on the original characters and their journeys to find their "true feelings" with the help of the Virtual Singers.[7]

In order to enter SEKAI, one must find and play the song "Untitled". This silent song has no melody or lyrics and is created at the same time as the SEKAI, and is mysteriously inserted on their devices. It can be anything, such as a game console, a smartphone, a smartwatch, a TV, a tablet, and a computer. When they play an "Untitled" song, they can travel between the real world and the SEKAI. As one is able to discover their true feelings, the song will contain a playable melody and lyrics, and well as its title.

Story

[edit]

Each of the five groups and members has their own story, focusing on their journey to convey their "true feelings":

  • Leo/need: Ichika Hoshino wishes to recover her memories with her childhood friends (Saki Tenma, Shiho Hinomori and Honami Mochizuki), to make them come together again, as their friendship had become strained in the aftermath of various circumstances that occurred during middle school. She entered the School SEKAI and met a punk-rock-styled Miku, who told her to convey her feelings to her friends and overcome their differences. Ichika and her friends eventually formed a band to restore their friendship and discover their shared memories through music.
  • MORE MORE JUMP!: Minori Hanasato has always dreamed of becoming an idol. Despite having failed auditions multiple times, she never gives up and hopes to pass an audition one day. She later entered the Stage SEKAI and met an idol-like Miku, who encouraged her to make her dream come true. She then formed an idol group with three former idols (Haruka Kiritani, Airi Momoi and Shizuku Hinomori) who retired from their career due to problems with their agencies.
  • Vivid BAD SQUAD: Kohane Azusawa has been deeply passionate about street music ever since she stumbled upon a singing session by An Shiraishi. Captivated by her singing, Kohane joined An to become a street musician as well, and later teamed up with fellow musicians Akito Shinonome and Toya Aoyagi. She entered the Street SEKAI and met a hip-hop-styled Miku, and together they began the quest to surpass a legend.
  • Wonderlands x Showtime: Tsukasa Tenma has always wanted to make his sickly sister, Saki, happy, but as time passed, he couldn't remember why he wanted to be a star in the first place. He was hired to work part-time at the theme park Phoenix Wonderland, but the once-popular theater Wonder Stage he is assigned to has been deserted, unable to attract any visitors for years. There, he met Emu Otori, who desires to restore the theater to its former glory. Joined by Nene Kusanagi and Rui Kamishiro, they formed a musical theater troupe as they entered the Wonderland SEKAI and met a clown-like Miku, hoping to revive the theater's glory and make people happy.
  • Nightcord at 25:00: Kanade "K" Yoisaki has been homeschooled and becomes reclusive because of a trauma she sustained as a result of an incident in the past. She formed an underground music circle with her three online acquaintances (Mafuyu "Yuki" Asahina, Ena "Enanan" Shinonome and Mizuki "Amia" Akiyama), communicating over a voice-chat platform named "Nightcord" and meeting at 25:00 (1AM). None of them knew each other's true names or identities, only knowing each other by online aliases and through voice chat. Kanade was pulled into the Empty SEKAI by Miku, who urged her to help save Mafuyu, the group's lyricist who had mysteriously disappeared a week prior.

Characters

[edit]

The characters are divided into five groups of four, each with a theme related to the groups' backstory, complete with Hatsune Miku in a thematic design to sing alongside them, in addition to one other Virtual Singer or two (with the exception of Nightcord at 25:00, who start off with only Miku). As the game's story progresses, new versions of each Virtual Singer appear in the different SEKAI.

Their image color is Dark Purple, and they represent trauma. Nightcord refers to the online voice-chat platform the group use, similar to the real-life chat platform Discord.

Development

[edit]

The game was first announced on August 30, 2019, at Magical Mirai 2019.[8][9] The development is done by the Colorful Palette, a newly established subsidiary of CyberAgent's Craft Egg (developers of rhythm game BanG Dream! Girls Band Party). Yuichiro Kondo, the first producer of Girls Band Party, also serves as the producer for this game. The project started in 2017 and was initially being developed entirely by Craft Egg, but Kondo thought it was necessary to avoid a situation where the project would clash with the development of Girls Band Party, so he created Colorful Palette with Craft Egg's core members within the company.[10][11][12] It was developed with Unity, and uses Crypton's Piapro Studio NT engine for speech synthesis.[13]

The title is a rhythm game that features arrangements of songs made by various artists over the years using the Vocaloid software. The original story of the game is told in a visual novel and musical film-style. The direction of the game's design and concept is different from other Hatsune Miku-related games, such as Sega's Hatsune Miku: Project DIVA, where the player and Hatsune Miku face each other directly and communicate in the game. The project is said to be "a work that embodies the existence of Hatsune Miku" and explores the relationship between music and people. One of the reasons behind this format was the idea of "wanting the younger generation to listen to more Vocaloid music and other songs from the internet." Therefore, while knowing that there could be people opposed to the idea of addition of original characters, it was decided to develop such a setting.[14]

Release

[edit]

The game's pre-registration was originally set to begin in late April, but was delayed until further notice due to the COVID-19 pandemic.

Nuverse released the game for the Hong Kong, Macau, and Taiwan markets on September 30, 2021. Nuverse is also managing the release in mainland China, South Korea, and Southeast Asia, with a release date to be announced. Sega released the game for all other regions (especially Western world including Oceania, Europe and North America) on December 7, 2021.[1][5] The game was released on 25 September 2023 for Southeast Asia, said to be an extension for the global server.

In real live events

[edit]

Concerts

[edit]

The game has held two types of live concerts: SEKAI Symphony and Colorful Live.

SEKAI Symphony (セカイシンフォニー) is an annual orchestra concert for the songs that has been featured in the game. It is held annually held at Pacifico Yokohama and is performed by SEKAI Symphony Special Band of Tokyo Philharmonic Orchestra. The first concert, held on October 16, 2021, featured Tsukasa Tenma and Nene Kusanagi's voice actors Daisuke Hirose and Machico as guests.[25] The second concert was held on June 11, 2022, featuring the voice actresses of Nightcord at 25:00 (Tomori Kusunoki, Rui Tanabe, Minori Suzuki, and Hinata Sato) as guests.[26] The third concert was held on June 10, 2023, featuring Ichika Hoshino and Saki Tenma's voice actresses Ruriko Noguchi and Karin Isobe as guests.[27] The fourth concert was held on June 8, 2024, featuring the voice actors of Vivid BAD SQUAD (Akina, Tomomi Jiena Sumi, Fumiya Imai, and Kent Itō) as guests.[28]

It follows the nature of Magical Mirai, an annual Miku-centered live concert, where all of the 26 characters (20 original characters + 6 Virtual Singers) will sing and dance along with real life band performers. The first concert, titled Colorful Live 1st -Link- was held on January 28–30, 2022 at Makuhari Messe. There was also paid live stream held on Abema TV.[29]

Anniversary event

[edit]

An annual event called ''Project Sekai Thanks Festival''[c] is being held on late September to celebrate the game's upcoming anniversary (September 30).

The second event was held at Tokyo Dome City Hall on September 16–17, 2023. The third event will be held on September 26–27, 2024 at Yokohama Buntai.

Creators Festa

[edit]

An event that "connects fan and creators" which features Vocaloid Producers and Vocaloid related illustrators is being held annually since 2023. It is similar to comic market where creators tend their own booth and sell their own goods. There are also official goods featuring original characters and virtual singers.
