Tsumugi Kotobuki

A wealthy and gentle soul, "Mugi" lives a luxurious lifestyle in a grand mansion but finds true joy in the simple, "normal" moments shared with her Light Music Club friends. A classically trained piano prodigy, she transitioned to the keyboard after being recruited by Mio and Ritsu. Despite her elegant, high-society upbringing, she possesses surprising physical strength and a playful, occasionally rebellious spirit, often bringing delicious treats from her family's business to enjoy during club tea sessions.
