Nao is very shy once you first meet and prefers not to have any attention, but once she gets to know you she is very energetic and loves attention. She's a prankster as well and loves funny things. She's very loyal to her friends and doesn't like getting anyone in trouble. She's easy to talk into things and doesn't like people getting angry at her, she can be very senstive. But she also likes to argue and will sometimes start one just for the fun of it, but she doesn't like it if the other person is truly angry at her.
Nao has a bad habit of giving up if something seems to hard or to much trouble, she doesn't have much self confidence at all. She also bites her bottom lip alot and makes it bleed alot as well.
She has a black leather choker with a silver ring in the front, her older brother gave it to her as a joke because he always had pulled her by her hair when he was in a rush, but after she began wearing it he just pulled her by that. He also gave her a small white kitten, which she put black streaks on. She has a White DS that she always keeps with her, it's the first thing she bought with her own money. Her brother is very special to her and always keeps in contact with him as well.
Nao is very good at drawing and sculpting, as well as gaming because she always has her DS with her, another thing she's good at is her aim.
Nao's mother died a short time after she was born, her father murdered soon after, he was a Yakuza boss in Japan. Kataro, Nao's older brother, was supposed to take over for his father but refused to instead take care of Nao, he was actually thirteen when she was born, but very mature. Kataro and Nao grew very close, he finished high school and went to college then got a job to support them both. As Nao got older, Kataro got more worried about her shyness problem and would always try and get her to be more flamboyant like he is, but so far it hasn't worked.
