This is Luka Megurine. Unlike previous mascots in the series, her costume is not based on a school uniform. Her design incorporates woodwind and brass instruments. The gold curl design on her chest mimics brass instruments and a circulatory organ. The blue jewel near her throat represents moisture in the air and water drops. Her item is Tuna. In most cases, she is romantically paired with Miku, creating a yuri atmosphere.
