Killer Bish (stylized as KiLLER BiSH) is the third album by Japanese idol group Bish released through Avex Trax on October 5, 2016. The album is the first full album by the group to be released from a major label. The album is the first release to feature new member Ayuni D, who joined the group in August 2016 following the departure of Hug Mii. Unlike their independent label albums, songs from the album were not released as free downloads prior to release. However, the album was released in its entirety in digital format a month prior to the physical release. The first 24 hours of the digital release had all of the group's releases including KiLLER Bish priced at 300 yen. The album was preceded by the single "DEADMAN", released on May 4, 2016. The music video for the track "Orchestra" was posted on YouTube on September 9, followed by the video for "Hontou Honki (本当本気)" on October 5. RUKA from visual kei band Nightmare, a well known fan of Bish and BiS, provided the music for the track "IDOL is SHiT". The track title is an homage to BiS's album Idol is Dead while the track is an homage to the song "IDOL" from that album.
Departure of Hug Mii and Entry of Ayuni D
Shortly after Bish had made their major label debut with the release of the single "DEADMAN", it was announced on Bish's official website on May 12 that original member Hug Mii would be leaving the group, and that their June 2 concert at Akasaka Blitz would be her last performance. New Member Ayuni D was revealed to the public on July 26, and she made her debut appearance on August 24 at the encore of their TOKYO BiSH SHiNE repetition concert at Zepp Tokyo. Ayuni D joined the LESS THAN SEX tour on September 1 in Nagoya. Ayuni D appears on the album as a full member, and Hug Mii's parts for DEADMAN have been re-recorded by Ayuni D on the album.
