About
The hugely popular musical duo "Mukimei." This two-piece band, consisting only of a guitarist and a drummer, is a hit with younger audiences. Their music is primarily instrumental, with few vocal tracks. They made a brilliant debut after gaining overwhelming popularity at a newcomer band festival and are currently the band to watch! Recently, they have expanded their activities to include TV appearances and casual chat streams on video sites. The stark contrast between their cool stage presence and their relaxed streaming personas is a major part of their appeal. However, the biggest reasons for their popularity remain the high quality of their music and their stunning visuals. On stage: Cool and powerful. Streaming (Off-duty): Cute, soothing, and wholesome. Guest Setting: Manager of "Mukimei."
