Don't worry

Felicita (the heroine), is a strong both will and body.
She is the only daughter of mafia family (Arcana Famiglia). She used to live apart from her father mansion with only her japanese mother Sumire and the attendant Luca. Several months before the game started, she got into the family and quickly become a division's head, with her own power only. All high members of family hold a special power called Tarot, and Felicita is the only one that hold two tarots, one of them allow her to read people's mind (and beside tarot she also has a deadly kick and a good knives user). The game start with Mondo (Felicita's father and family's head) birthday party, in which he announced his retirement soon. To decide his successor, he announced a Arcana Duello, a duel amongst tarot's users. The winner will become the family's head, get his one wish fulfilled by Mondo, and marry his daughter. On top of that, Felicita will be banned from going outside mansion after her marriage. Felicita of course oppose this, and to make herself free, she should win the duel.
Well, that the basic story. Although I only played it only until passed the prologue.
