Shirogane Haruna is a highly skilled puppet master hailing from the Hidden Sand Village. She had trained with the puppets since she about 8 years old and earned two of her own just two and a half years later named Cyder and Ace. Despite carrying her two puppets all the time, Haruna is very quick on her feet and tends to stay away from the fight if she actually could. Like the other puppet users in her clan, Haruna can use more than one puppet at the same time for combos and other stuff.

Haruna isn't that big on working in a group on very important missions and she hates it when people diss her on her battling tatics with her puppets. She takes pride in her ability as a ninja from the Sand Village and when she isn't taking care of her beloved puppets, she loves to hang out with her close friends and train with them.
