Mayuzaka46 (まゆ坂46?), or Mayu46 to some, is a special AKB48 and Nogizaka46 collaboration unit created for the song Twintail wa Mou shinai from the single Otona Jelly Beans.
- AKB48 (Team B): Watanabe Mayu
- Nogizaka46 (1st Generation): Ikuta Erika, Ikoma Rina, Hoshino Minami, Hashimoto Nanami, Shiraishi Mai, Matsumura Sayuri, Nishino Nanase, Fukagawa Mai, Ito Marika, Inoue Sayuri, Sakurai Reika, Takayama Kazumi, Nakada Kana, Fukagawa Mai, Wakatsuki Yumi
During the AKB48 Group Janken Taikai 2014, when Kojima Haruna was matched up against Ikoma Rina (who has a concurrent status in AKB48 at that time), Kojima brought along 4 members of Nogizaka46 (Kawago Hina, Nagashima Seira, Saito Yuri, and Nakada Kana). This formed the impromptu unit Kojizaka46 (こじ坂46?). After Ikoma lost, she was recruited into the unit by Kojima as part of a wager.
The official members of the sub-unit were introduced in "Nogizaka46 Under Live Second Season". They performed Kaze no Rasen, the Type-D coupling song for Kibouteki Refrain, AKB48's 38th single.
- AKB48 (Team A): Kojima Haruna
