Mimi Usakawa operates as DJ.Lovit within the Card Jockey team in the virtual WIXOSSLAND, alongside teammates Nana Nekozawa (MC.Lion) and Rara Inumiya (VJ.Wolf). She serves as the voice of reason during the team's activities and battles. Mimi shares a long-standing childhood friendship with Nana Nekozawa, which informs her understanding of team dynamics and supportive approach during collaborations.

Her visual design features bubble gum-pink hair with curled ends and distinct eyes, complemented by a black bunny ear headset with magenta accents. Her attire includes a short gray and fandango pink sleeveless top with frilled black cuffs, elongated gray arm covers, and a short gray bottom layered beneath a disconnected black belt. Additional elements are pantyhose, fluffy magenta leggings, a black collar around her right leg, and black high-heel shoes.

Within the trading card game, she is represented as a red LRIG type named LOVIT. Debuting as an assist-only LRIG in specific card sets, she later became a playable card in subsequent releases. Her team, Card Jockey, competes in three-versus-three Diva Battles where units vie for fan support from audiences called Selectors.
