About
The "Wonderland Sekai" is a place like an amusement park. It's a world filled with impossible attractions: singing flowers, walking and talking plushies (which speak in Katakana, like "HUNGRY! PLAY!"), and flying trains. Six Virtual Singers reside here, starting with Hatsune Miku, followed by Kagamine Rin & Len, Megurine Luka, MEIKO, and KAITO. They perform shows with the members of "Wonderlands x Showtime" and support their practice by giving advice. Items can be brought in, but nothing except personal belongings can be taken out of the Sekai.
