History
BPM15Q, 2015-2016= In June 2015, BPM15Q, a Yume-kawaii themed electro idol unit was founded by Ichigo Rinahamu and Nicamoq. They held their debut live on June 20th at Sound Note Nagoya.

Starting in September, BPM15Q began releasing self-produced CD-Rs starting with Hakuchuumu / HANNARI.

BPM15Q's first "official" single, online 1st, was released in May 2016. It would be the only single released as BPM15Q.

On November 23, 2016, they released BPM15Q all songs, their debut album.

In December, Nicamoq announced that she would be graduating by the end of the year. In response to Nicamoq's departure, Rinahamu announced that BPM15Q would continue under a different name, and auditions for new members were announced. 2017= Following Nicamoq's graduation, Koinumaru Pochi and Suzukawa Mashilo (formerly of the idol group DEEP GIRL) were added in January 2017, and the BPM15Q changed their name to CY8ER.

CY8ER's first single (second overall), Remix Start, was released on March 18. They released one more single as a trio, Te to Te, a month later.

Shortly after the release of Te to Te, CY8ER announced through a video posted on their YouTube channel that three additional girls would join the group; Yamiyume Yamii, Naatan Coromushi and Fujishiro Anna (formerly of Bellring Girls Heart and Ice Cream Suicide).

CY8ER's first single with six members, Kakusheemu, was released in late June. They also held their first one-man tour, CY8ER LUCID DREAMING TOUR in 2017 with a total of 3 venues, the final taking place in Osaka.

In summer of 2017 CY8ER also entered the Idol Matsuri competition, winning 1st place for the Kanto-A block. 2018= On January 31, 2018, CY8ER's first album, Hello New Generation, was released.

On March 5, Naatan Coromushi suddenly withdrew from the group. A statement released on their official website said:

"'We have talked to (Coromushi) about her future over and over, but when the circumstances continued, judging that the group will be struggling to continue as a group, Naatan Coromushi will be withdrawing today."

"We are hoping that you can understand the situation, it is a bitter judgement as a result of repeated consultations for several months between the Manager, the staffs, and the members.'"

On July 28, CY8ER released the digital single Bye Bye, their first release with five members.

Throughout 2018 and 2019, CY8ER frequently promoted and modeled for the Galaxxxy fashion brand. 2019= On January 22, 2019, CY8ER was announced as the official supporters of the Honolulu Rainbow EKIDEN 2019 which will take place on March 10th at Kapiolani Park, Hawaii. This would be their first performance in the USA.

In February, CY8ER announced that they would release one single every month for three months. The first of these singles, Dead Boy, Dead Girl, was released in February, the second Time Trip was released in March with the third and last being Summer / Sayonara Flashback released in April.

On October 18, CY8ER also held a free "emergency" live where a serious announcement would be made about their future. At the event, CY8ER announced that they would have their major-label debut in January 2020, with the album, Tokyo. That same month, they also launched their official fashion brand, CY8ER TOKYO, selling jackets in each of the members' respective image colors.
