Brave Entertainment said that Hip-Kongz's debut song will be released through music websites at 6 p.m. (0900 GMT) on May 30. The new single portrays a virtual artist who was left alone in the night. Hip-Kongz will share his love stories in the past and express his various concerns about his reality and future. The virtual rapper's voice actor was not disclosed.
The virtual artist was developed through Brave Entertainment's PFP non-fungible token (NFT) project. PFP refers to "Picture for Proof" or "Profile Picture" and is used to prove the ownership of NFT, a unit of data stored on a blockchain network of interlinked virtual ledgers.
