D4DJ Groovy Mix is a rhythm game developed by Mobimon Inc. based on the DJ-themed multimedia project "D4DJ." The game tells the story of six DJ groups, each with their own unique music style, who dream of performing on the national stage at the "D4 FES." The game features a mix of original songs and popular remixes from across generations, allowing players to experience rhythm operations from a DJ's perspective, including scratching and mixing.

One of the most exciting features of the game is the live performances of the 24 female DJs, who are brought to life with full voice acting and Live2D animations. Players can interact with each DJ and enjoy their unique music style, as well as immerse themselves in the beat of the game's "immersive electronic rhythm" gameplay. With high freedom gameplay, players can challenge themselves with expert-level full combos or simply enjoy the slow electronic rhythm through the auto mode.
