GRADUATION ANNOUNCEMENT OF SACHI MEMBER
First words, Niji Universe Inc. We would like to send our sincere thanks to all the audiences who always support the group.
Today, Niji Universe Inc. We would like to announce that member Sachi will officially graduate from the group from today due to health reasons that cannot ensure the group's schedule and other personal reasons.
Because Sachi's health does not allow it, Niji unfortunately cannot hold a graduation live show. Niji very sincerely apologizes to the audience.
Niji would also like to send his sincere thanks to all the viewers who have been supporting Sachi in the past. Hope Sachi will have success on her new path.
Niji also hopes that the audience will still support the groups in their next projects.
