2 AKB48 kenkyuusei students have resigned from the group and will leave next month. Nau Yamaguchi and Sara Ushikubo put in a request to withdraw. No reason has been given to fans as to why they wanted to quit. I can’t say I’ve noticed these two before. I guess they’re not one of the kenkyuusei students that are starting to become popular with AKB48 fans such as Fresh Lemon. Good luck to them.
