Her initial design was conceptualized by Hiroto and modeled by LAT for an MMD PV. The name "CUL" has double meanings, short for "culture" and "Culnoza", a collaborative group organized by Hiroto-P. A 3D model for MikuMikuDance model of Black CUL was released in 2011 by Lat, however, it is unknown if this was part of that concept. A twin version of CUL, "黒CUL" or "Black CUL", was also conceptualized. CUL was the youngest of four and each character was based on a different color: blue, white, yellow, and red.

In the same Tweet, Hiroto-P revealed that CUL was to have siblings. In September 2020, it was revealed by Hiroto-P on Twitter that REV was planned to become a VOCALOID like CUL, however, progress on the project fell through. Like CUL, REV was given a 3D model by MikuMikuDance modeler Kio and was intended to use VY2's vocals. In 2011, a male counterpart for CUL named REV was revealed and confirmed to be designed by CUL's creator, Hiroto-P. Several music videos were uploaded featuring a 3D model of CUL created by Lat, utilizing vocals from VY1 prior to CUL's release as a VOCALOID. ĬUL was first introduced as the mascot for the show "VOCALO Revolution", and like Lily before her, CUL was not part of Internet Co.'s "poid" series. However, the information was posted for her in 2013 when she was featured in a special event. Originally, CUL was released without background information.
