About

Isolated from most of the world, Illya grew up lonely, trained for the specific purpose of serving as a vessel for the Holy Grail in the Fifth Grail War. Her knowledge of life outside of her home is lacking, and she didn't particularly see any reason to learn considering she believed that she would die soon regardless of what she did.

Now thrust away from the Fifth Grail War, she's experiencing a level of freedom she'd never experienced before with the power of a Demigod at her side and nobody to stop her from doing what she wants. And what she wants is to enjoy herself, exerting her power over the people around her, with the little regard for the well being of anyone around her, aside from Heracles.

Friends

Illya has never had a friend her own age, and has little idea how she would go about even getting one... And now that she has Berserker at her side, she has little desire to search for one. Getting to be Illya's friend would be complicated, less because she would resist it and more because Illya wouldn't even try to be friendly back. At least, at first.

Anyone who earns Illya's friendship is incredibly important to her, and she would become incredibly attached. She has a crippling fear of abandonment that makes her very clingy to anyone that she cares about, afraid that they'll leave her. It might get to the point of being overbearing for some people, but at her heart Illya is a very loving young girl, and she protects anyone she cares about with great ferocity.

Enemies

Anyone who stands in Illya's way would be considered an enemy by her... But the way she treats her enemies is a little different than most. They're toys to her, ways for her to amuse herself, and if they prove to be entertaining enough she might let them live so she can play with them later, until they break.

The only exception to this is anyone who harms, or threatens to harm, people she cares about, and anyone she believes has 'abandoned' her. Those type of people she will simply aim to destroy before they can cause any more problems for her, her vindictive streak coming out in full force. Its... Usually not a good idea to get on her bad side, mostly because she won't hesitate to sic Berserker on anyone.
