Where is the Glassheart Music?

The hit work adapted into a TV drama! High school student Akane Saijo is kicked from her band for the unreasonable reason that... she's a woman. She is then invited by genius musician Naoki Fujitani to join him in a band, and becomes a member of "Ten Blank" along with Sakamoto and Takaoka. This is the story of their souls as they walk the path of music together.
