The Lovely Black Widow
Shiori basically has two sides, a mean side and a sweet/sugary side. Her sweet sugary side is what the hosts and her guests saw.
Her sweet and sugary side is just that. She is extremely nice to everyone around her and she is never mean to people. She has that about here where she would never ever try to hurt a person. She would protect them and love them just like she would anyone else. She has a basic knowledge of everything, and knows about more things than others. Her IQ is very very high. She wants to be a lawyer and musical prodigy when she gets older.
Her mean side is very violent. Not to a point of killing people, but she is skilled in weaponry. She also is very very sarcastic when she's on this side. She can be bitter and cold-hearted.
As a person, Shiori has many friends, mainly guys. She isn't friends with many girls because of drama.
She likes the dark and generally doesn't get out much. She has two sharp teeth, but doesn't usually show it.
When Shiori is good and nice, she can play the piano and violin. She also knows how to play the harp.
When she's on her mean side, she can wield a sword, two different knives and knows martial arts.
Not to say that these skills don't go away when she's on different sides, so to speak, but she just doesn't use them. She is usually equipped with a knife at all times.
Shiori has a basically normal family, except for the fact that her older brother is an assassin. Like, a trained assassin from the FBI.
Shiori's father is a lawyer and her mother is a nurse. Her little sister is in elementary school, being only six.
Her brother, Ren, is 19 and isn't home much.
When Shiori was 10, her grandmother died. She was really close with her and when she died, she went into a state of depression, almost always being mean and dark and never really communicating with anyone. When she finally got out of that phase, she was in high school. At this moment, Shiori is 17 years old and has many friends.
Shiori learned her martial arts skills from her brother because he wanted to make sure she was able to protect herself when he wasn't around. Herself and their little sister in case that she got into trouble as well.
