Itsumi Hidaka was the daughter of a man from the japanese mafia, the girl was raised not by her father but by her companion, a shield that would protect her no matter what, Itsumi never knew her father since he always had to stay off the radar, but that didn't stop her from being attached to the Yakuza, in no time, she began to be respected as a rightful leader, planning for various illegal activities all around japan, but always leaving her mark and running from the law, she wanted to be the opposite of her father, she wanted the people to respect her and know that she was in charge, eventually making headlines around the world for her actions.

Itsumi has a really bad relationship with luck, getting into ridiculous situations very often, she can only cool down with few people around, as she is afraid that her mistakes may make her look weak...

An example of her voice would be [Miu Iruma from DRV3]
