By the way here is Nicola's description:
Gender: Male
Species: Coyote
Age: 20 year old

Nicola is a nerd who love to read different kind of books, he can be seen as a naïve guy and in fact he is, he tend to believe that every one is good and can easily fall in a trap.
But except that he is kind, shy, even if he like to socialise. He have an unconditional love for caramel, he always have a bag of small caramel sweets on him in case he wants to eat one or two during the day, but he usually empty the bag by the end of the day.
His parents gives him a little bracelet with a bell on it so that they would be able to hear him even if he is out of sight so that if he get in trouble they could protect him.
