Kadia Silver, previously known as DarkGuitarGoddess, is one of the youngest of the Author Fighters at the age of 14. She knows the basics in dark magic and Genin level ninja skills.
Along with her sister Phoenix, she grew up in the world of Unity. Her father, Marcus Silver, was killed when she was only three years old. She made a few good friends at the school she attended. Though by the time 5th grade came along, her sister went after Omega to avenge Griffin. Kadia couldn't go through the rest of school not knowing if Phoenix was doing okay, so she ran away from her home and went to Konoha.
In Konoha, she learned a few basic ninja moves, like the shadow clone no jutsu and sexy no jutsu from Konohamaru
