Looks like this is the end for Rhymeberry.
Oh, this is sad news. It says the group will resume with MC Miri and new members, but I can't really see it happening.
EDIT to add excerpts from Tokyo Girls Update article:
Idol rap unit “Rhymeberry” announced that MC HIME & HJ HIKARU have suddenly graduated from the group, and only MC MIRI remains behind. It was sudden and unexpected, there will be no graduation events or something like that. No future plan has been announced but MC MIRI plans to keep the group going.
Along with the 2 members, the producer Yoshikazu Kuwashima, a.k.a. E TICKET PRODUCTION, also left the group at the same time because of the expiration of his contract.
Tokyo Girls’ Update has been featuring Rhymeberry several times. They showed an amazing performance at the solo concert from the end of the last year and seems that they were definitely on the rise.
Actually this is not the first graduation for the group. MC YUKA left the group in April 2014, but even after the shock, the group has been grown up so rapidly from now.
They will have their next performance on March 1st, and new members will appear on the stage. It seems that fans are really confused by this sudden change, so the March 1st’s performance is being anticipated with mixed feelings.
