Rikka Isurugi is my name, and I’m descended from the Isurugi Ninja Clan. I was trained in the ninja ways all of my life, so I’m a pretty skilled fighter. I became a detective and later a superhero, the Black Fox, using I’m actually a friendly, laid-back girl, who likes to joke around and have fun. I’m super smart. I’m a great detective and investigator. I was originally consumed by revenge, but I’ve mellowed out now. After your father’s and grandfather’s deaths, you have no known family.
