At today's SKE48's Kenkyuusei theater performance, 3rd gen KKS Imade Mai announced her graduation. The reason for her announcement was for her wish to study abroad and also because of a leg injury.
She also made a G+ post concerning this:
At today's theater performance,
I, Imade Mai, was allowed to make an announcement about my graduation.
Another time, I will write a detailed post.
For now, I'm sorry.
This is really sad as Mai is the 4th member from SKE to graduate this year. The vacant spot left by Matsushita Yui and Nakamura Yuka as they graduated last year from Team S and Team E respectively still hasn't been filled and now we are losing another one and a kenkyuusei at that. This is all very disheartening.
