Siri is a hybrid of Vampire and mortal as well Otter and Fox. She is normally an enigma to most people because of her being 100% homeschooled, thanks to being hybrid. Unlike her siblings and other relations, she doesn't really drink blood. She can fly and see well in the dark, but severely dislikes the taste of blood. Her father, Thorin (Samster's biological father), is where she got her otter half (pun intended.) and mortal half, since he didn't fully finished the whole vampire ritual when doing the do with her mother.

She is mainly a vegetarian, and by that I mean she does not eat people flesh like her older siblings. Her eyes don't really glow red, but she can actually see well in the dark.
