Cristina was born into a "wealthy" magical family in Cork, Ireland. She is the youngest of five siblings who, next to her parents, are the role models she looks up to. Her father works as an auror, and he has tought her to always do what is right and to never be selfish. Her mother, a muggle born witch, works for the Ministry of magic and she has tought her to fight for what she wants and to never give up. Living with her 4 older brothers (current Hogwarts' students), she has learned to be brave and to defend herself. Her whole family is a Gryffindor, so she expects to be sorted in the same house.

Her green eyes are said to shine more than usual when she is contriving some king of adventure. She has a rebel chesnut colored hair wich always ends up messy althought she brushes it a lot. She has a thin and athletic body due to the fact that she dances ballet. She is not tall but she is not small either.

Always seeking for adventure, young Cris (short name for Cristina) is considered to be the most active and playful girl on town. Since very early she has stood out for her independence, strong personality and energy. Cris has her own opinions and isn't easily influenced by others. She makes friends everywhere she goes, and charms everyone with her cute smile and contagious laught. You will never see her being bored, she will always be practising a sport (such as quidditch, sailing, windsurfing or dance), making new friends, trying new things, or playing in the woods arround her family residence. Her dream is to be on a school quidditch team.

Even though she loves to have fun, Cristina is also very sensible and responsible, and has A+ average marks in muggle preschool. She is a lot like her mother, quick- witted, smart and a bit of a perfectionist. Cristina has a natural hability for making the most of each day : she always has time for everything, it is just how she organises herself.

She is not the kind of girl who gets intimidated by people, so she usually ends up defending others.
She firstly experienced magic two months ago, when at the muggle school she has been atending, a group of older muggle boys were teasing one of her friends. Cris got very angry her face turned red. Instictively she started a fire on the uniform of one of the bullies. They run away screaming.
Since that incident she has learnt to control her impulsed a little but she knows she still has to learn a lot.
