Nikita
Nikita is the tomboy member of the Wolf Pack gang who develops a crush on Alfredo. At first, Romeo and the rest of the Black Brothers did not know that she is a girl, except Alfredo who revealed her secret after the Wolf Pack gang lost in their battle at San Babila Church. Dante develops a crush on her after he knew that she is a girl. Nikita became more friendly to Alfredo, Romeo, and the other members of the Black Brothers in later episodes of the anime series.
She was deeply saddened by the death of Alfredo. In order to recover from her depression, she swam in a river even though she knew that it was very cold because of the winter season in Milan. Before Alfredo died, he told Nikita to put a flower in her hair and that he will come running to see if she did. In the last episode of the anime, Nikita is shown wearing a flower in her hair. Before Romeo returned home to Sonogno, Nikita promised to him that she will take care of Alfredo’s grave.
