Liella! is the school idol group in the project Love Live! Superstar!! Originally in the first season of the anime, the group had five members, who have performed numerous times on tv shows or on live concerts (There have been dozens!).
In an online event today (June 8), the long anticipated other four members of the group appeared for the first time live online.
Since the start of this project, Liella! had always been a group of five. Some fans were quite emotional when it was announce that four other members would be joining, which might be one of the reasons fans are actively discussing tonight that the tag goes trending.
