She is a young vampire girl with curly, blonde hair. A horde of vampires attacked her human home when she was 8, killing her older sister and parents and leaving her to be dragged to Hell and transformed by the Devil himself. She has no ability of speech.
She is usually happy and bouncy, still unsure of the ways of the world. However, upon meeting new people, she tends to be timid and shy. She is easily frightened and sometimes feels the hurt of her lost family, but she tries not to let it show.
Ionca has gained powers from the Devil. They allow her to automatically heal her injuries, though the process tends to be tedious and slow. She uses a staff and a form of "holy aura" (white glow) to deliver powerful attacks. At times, that aura may turn into "sinner aura" (black glow), which strengthens her powers ten-fold. Unfortunately, this power deals a great damage on her little body if used more than is necessary, and can often be quite painful, emotionally and physically. It is not at its full strength unless it is unrestrained, which has never been done, before.
She grew up in a house on the countryside with her older brother, Hype, her older sister, Ellie, and her parents. Her father was a brute type of man and her siblings often strove to protect her from his ruthlessness, and so Ionca lived a happy life as a human. Her best friend was her neighbor, Roy, whom she played with down by the river daily. However, one night, her family was attacked by a horde of vampires, who slaughtered her parents and her older sister, but she was dragged off before she could see what happened to her older brother. She was taken to Hell, where the Devil had called upon her, and he himself turned her into a vampire. He then took her voice from her and threw her back into the real world to fend for herself, without any memory of ever being in Hell. However, she remembered the vampires at her home, and had assumed her brother to be dead, along with her elder sister. So, she travels alone, in search of some place to call home.
