On July 8th at Tokyo Bigsite, AKB48 held a drawing for group placements for upcoming 3rd Janken tournament which will decide Senbatsu members for AKB's 29th single.
All 86 members who will participate the tournament drew lots. Watanabe Mayu(18), who won 2nd spot in the election is seeded for 1st round and will join the tournament from the 2nd round. Besides, her opponent that she will face in the 2nd round already declared her withdrawal from the tournament, so Mayu will be selected for Senbatsu by just winning only one battle, the 3rd round. The member who declared withdrawal is Masuda Yuka (20). The reason for her move is because she wants to focus on her work for Miyamoto Amon produced musical "Whiz".
The last tournament's winner Shinoda Mariko (26) will join from the 2nd round and will face Ohya Shizuka (20), who is also in team A and also from Fukuoka, the hometown of Shinoda.
