Here’s Su-Metal performing in Karen Girl’s in front of a MASSIVE crowd in case anybody didn’t know that she is actually a very seasoned veteran in the idol scene. Already part of a huge group and performing in front of huge crowds since the age of 11!
Karen Girl’s (可憐Girl’s) was a Japanese pop idol group from 2008 to 2009 under the label Geneon and the agency Amuse. The group was formed as a teen idol group that featured three elementary students. The group released their first single, entitled “Over The Future”, in 2008; the title song was used as the opening theme for the anime Zettai Karen Children. After the show ended in March 2009, the group dissolved and each girl went their own way in their career.
Karen Girl’s were Ayami Mutō, Yuika Shima and Suzuka Nakamoto
