Dance and vocal group E-girls (and also Happiness) member MIYUU announced through the group's official site that she would be receiving surgery on her left knee. 

According to the announcement, her knee condition has been bad since mid January, and after an examination, she was diagnosed with damage to her lateral meniscus on her left knee. 

MIYUU commented, "I won't be able to perform for a while, but even during that time, I will do everything I can do. I will also do my best for the rehabilitation so I can show you my best performance again."
