This one is quite late as the profiles have been up since early December but I totally didn't notice them until recently when I checked the site for something else. My fault. The 11th gen Kenkyuuseis made their debut appearance at the AKB48 Tokyo Aki Matsuri with 10 members. However if you count the pictures above, there are only 7. The 3 missing girls, Toyoda Saki, Kawakami Marina and Okazaki Chinami, has since left the group due to personal reasons. The remaining have been performing regularly in the AKB48 Theater. All of them will be singing in Ougon Center in the upcoming Sakura no Ki ni Narou Single.
Just judging by their faces and voices, I would say that my favorite would be Kawaei Rina, followed by Natori Wakana and Suzuki Shihori.
