Canon
Ichika, Minori, Kohane, Tsukasa and Kanade are all in different units, but they are all the leaders of their units; Leo/need, MORE MORE JUMP!, Vivid BAD SQUAD, Wonderlands x Showtime and 25-ji Nightcord de. All of them are also girls, with the exception of Tsukasa. Ichika, Minori and Kohane attend Miyamasuzaka Girls' Academy while Tsukasa attends Kamiyama High School and Kanade takes online classes. Ichika, Minori and Kohane are first years while Tsukasa and Kande are second years.

Minori and Kohane are the only classmates within the group, and they are also best friends. Ichika is childhood friends with Tsukasa since he is the older brother of Ichika's childhood best friend. Ichika also became friends with Minori and Kohane when she sang with them in the "Singing Among the Cherry Blossoms" event. Ichika became friends with Kanade at the music store.

The five of them have plenty of official art together, along with Hatsune Miku, due to them being leaders of their respective groups.

Scramble Fan Festival!
Ichika, Minori and Kohane talk about their worries as they eat lunch on the school rooftop together. This helps them feel less alone, and they work through things together. The trio also decides to go to a VIRTUAL SINGER Fan Festival together. The three bring Nene to the Fan Festival, and she gets the rest of her troupe to help prepare for the festival. Kanade hears about the festival online and decides to attend as well.

There aren't any interactions between the group as a whole since Kanade didn't interact with them. Tsukasa does cheer up Minori and give her courage to go on stage.

Fanon
Polyleaders is a rarepair, but there are some people that do ship it. Since there aren't a lot of interactions between the group, people tend to ship each of the characters with characters in their unit instead. Polyleaders is mostly rivaled by Ichisaki, Minoharu, Anhane, RuiKasa and Kanamafu, though there are many other rivals. Polyleaders is mostly seen as a friendship rather than a romantic ship.
