NS Yoon-G (formerly known as NS Yoonji) has released her new mini-album, 'Neo Spirit'. As the title indicates, the singer has returned with a 'new spirit'. She's departed from her sweet pop flavor to something more edgy and loud, a transformation that's reflected in both her image and sound. Decked in leather and spikes, NS Yoonji proves she's made a dramatic image transformation with her title track "The Reason I Became a Witch". Check out her comeback performance on 'M! Countdown' below.
