CY8ER (formerly known as BPM15Q) was a Japanese "new age vocal & DJ unit." formed by ex-BiS member Yokoyama Rina (under the name "Ichigo Rinahamu") and Nicamoq in 2015. The name BPM15Q referred to both of the original members, with 15 referencing Ichigo Rinahamu (1 = ichi, 5 = go), and Q referencing Nicamoq. Nicamoq left in late 2016 and the group was renamed to CY8ER following the additions of new members.

CY8ER's musical genre is commonly described as a mix of Future Bass and Drum & Bass, both subgenres of EDM.

Ichigo Rinahamu is the producer of the group.

CY8ER disbanded in January 2021.
