three online acquaintances, 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 Sekai by a gothic-styled Miku, who urged her to help save Mafuyu Asahina, the group's lyricist who had mysteriously disappeared a week prior. After the introduction movie, the player must choose one of the five orbs three times. If at least two orbs have the same color, the game will automatically reveal a group (e.g. if the player picked all blue orbs, it will reveal Leo/need). However, should the player choose different color orbs, it will choose the group associated with the last color they choose. There are three types of stories. First are group stories (or Main Stories), focusing on the backstory of one particular group, more of which become available as that group reaches higher ranks. Card Stories, on the other hand, revolve around one individual character with two parts. The first part becomes available upon acquiring the prerequisite items for the card, while the second part is unlocked by leveling up the card. There are also time-limited event stories, which are unlocked by playing the event. They are further divided into two types of stories: standalone stories focus on single groups, while mixed stories feature characters from different groups. Event stories are re-added to the game permanently 2 days after the event ended. Characters 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, and one other Virtual Singer (with the exception of Vivid BAD SQUAD, who have three, and Nightcord at 25:00, who only have Miku). As the game's story progresses, new versions of each Virtual Singer appear in the different Sekai. Currently, in the Japanese version of the game, each Sekai has a version of every Virtual Singer except KAITO, who is only yet to appear with Nightcord at 25:00. Leo/need An all-girl pop-rock band formed by a group of childhood friends who have learned to overcome their differences. Their Sekai consists of a classroom bathed in the afterglow of the sunset. They are initially supported by Hatsune Miku and Megurine Luka, who take on the form of band musicians. Their image color is Midnight
