Details have been released on AKB48‘s upcoming 50th single 11-gatsu no Anklet. This release is a big deal for fans, as it will serve as the graduation single for last remaining original “Kami7” member Mayu Wantanabe.

The single will have 10 different versions in total, 5 regular editions and 5 limited edition versions. Limited edition versions of the single will include an event ticket and voting card for “AKB48 Group Request Hour Set List Best 100 2018”. Regular versions of the single come with a random photo along with a voting card.

Wantanabe’s graduation song Sayonara wa owaru wake janai will be included on every version of the single, while 5 additional b-sides will be included on the various different versions of the single. This includes a song by STU48 titled Omoidasete Yokatta , and a song by Team8 titled Ikirukoto ni Nekkyo wo!

Type C versions of the single will feature a song by a completely new unit, however details on the song and unit name have not been revealed yet. Short version MVs of both 11-gatsu no Anklet and Sayonara wa owaru wake janai have been uploaded on AKB48’s official YouTube account.

The girls take a somewhat “artsy” approach in this MV. Donned in high-end designer clothes, the video starts with Wantanabe sitting in an empty room with her hands in her face. She begins to dance around the empty room and paint things with a “magical brush”. The next scene involves three members sleeping in a giant box located on the beach. After waking up they decide to dance on the beach and use mini rainbows as hula-hoops.

Sayonara wa owaru wake janai is a dramatic ballad that will surly cause some tears to fall at Wantanabe’s graduation concert.

11-gatsu no Anklet will be released nationwide in Japan on November 22nd, 2017.
