Prologue

Myoui Mina is known for being the most elegant and sophisticated student in Morning Star School of Fine Arts (owned by her family.) She was not aware that she was different from everybody until her 18th birthday. She discovered that she's a half-demon and half-human being -- the only daughter of Lucifer.

Can she still live a normal life? How long can she keep her dark secret from everyone? Can she still hide her true identity especially from the person she loves dearly?
