崇拝者 ～囚われのカナリア～

Idol girl Makihara Karin brings her passionate voice to those who have faith in her. She sings in duet with a dreamy girl Rin Misugi. Entertainment world is full of darkness and craziness. Fans are like worshipers who dye their hearts in darkness for their goddesses to shine brightly. Melody flows from these fallen girls like a sad hymn in preparation for the sacrifice.
