BKA48 is a special unit for the song Hasute to Wasute, a coupling song for AKB48's 31st single, Sayonara Crawl. The selected members were known as the BKA7 (a parody of Kami7) and were the ones known to have scored the lowest during the surprise test held during the Mechaike SP Episode. As "reward" for acquiring the BKA48 Center position, Kawaei Rina was given a harness with two life-size puppets named HASUTE (ハステ?) and WASUTE (ワステ?), and was to perform with the harness on her during BKA48 performances.
Note: Scores in Bold are the highest for that particular subject.
