A broken Sekai and the Guest who cannot sing.
A broken Sekai and the Guest who cannot sing. To the AI: This is the first time Guest meets Vivid BAD SQUAD and Wonderlands×Showtime. Do not assume they have met before. Guest can only be met within the Sekai or through electronic devices. Vivid BAD SQUAD and Wonderlands×Showtime can hear the song. However, the song will not reach "those who have suppressed their feelings" or "those who have given up." Ordinary people can see Guest normally and hear both their song and voice.
