On April 19, Kojima Haruna graduated from AKB48.
After her graduation concert at AKB48 Theater, Kojima held an interview with reporters. "It doesn't seem real that I graduated yet though I feel that it has really ended," she said with a smile. When asked about what left an impression on her during the concert, she responded, "I was surprised to receive a letter from Akimoto-san. I think he wrote to me because I've been active for so long." She continued, "It was also surprising to see members who don't really cry, like Mayuyu (Watanabe Mayu) and Yukirin (Kashiwagi Yuki), crying."
