[Crossover] The Angel's Crown

A girl who has lost her past, apparently deceived in love by Chrollo. Is what lies behind this a distortion of human nature, or a collapse of morality? What if it's because she hasn't risen high enough? Could Athena of the Greek Sanctuary guide her toward the right path? Or could Professor Moriarty, who worries for his country, give her the one answer she needs? If the Holy Grail can grant wishes, could it help her recover the past she's lost?
