1st generation member Akimoto Manatsu wrote in her blog that she will graduate the group at her graduation concert on Feb. 26 at Yokohama Arena.
The last 1st gen member and the oldest in the group, Akimoto led the group as caption for the past 3 years. She was senbatsu 29 times (including “Route 246”), which puts her tied for 1st place all-time along with Takayama Kazumi. And she is one of the 11 members who have perfect senbatsu records (including graduated members).
