From the moment Rachel Carradine hears the dark, rich tones of Blackie Madigan's alto saxophone, she knows her heart and her hard-fought, well-ordered life are in danger. As the daughter of a jazz musician, she knows the seductive power of the music just as she is familiar with the insecure, irregular, bohemian existence of the musicians. She escaped that lifestyle once and promised herself that nothing on earth could induce her to embrace it ever again. Yet hearing Blackie's Orpheus-like melodies, she is faced with the greatest temptation of her life. But Blackie makes some dangerous assumptions about Rachel that threaten to derail their relationship before it even gets going. Unbeknownst to Rachel, Blackie is Blackstone J. Madigan, the entrepreneur behind the powerful conglomerate that owns Exotica, the company threatening Rachel's professional livelihood. Mistaken identities, secrets, deception—hardly a harmonious beginning. Rachel and Blackie must see if their relationship can overcome these major obstacles and decide how much they're willing to risk and if it will be enough. (Source: Japanese Publisher, translated)

The manga is set in a world where "demon-possessed" individuals appear every time there is a great disaster or war. The demon-possessed wield demonic powers, and if left unchecked, will use them to fulfill their selfish desires. The Holy Endor Academy was established to counter, secure, and re-educate these demon-possessed individuals. One day, a seemingly normal high school student named Konoha Himesaki enters as a low-class criminal, but she is in truth a powerful magic user.

Based on the Sega Saturn game by the same name. *Note: Released as Enix Supercomic Gekijoh Volume 11*
