Tori is the 'innocent' of the 9 idols, they tend to be sweet and caring to anyone, even with those that are bad with them! That is often bad for them, since they have been hurt several times due to their personality. Even if it looks like they are  silent and shy, once they start talking they won't stop! The style that they love to sing the most are songs that talk about love or sadness, since they find it so powerful and emotive. They also like it because it's a way of getting all the pain out of them, everything that once hurt them, they sing it out.
