Evelyn stands at 5 feet, 4 inches. Her hair's hue is that of a color known as 'sky blue,' (While this isn't the girl's natural hair color, she's dyed it for so long, that even her mother has forgotten what her daughter's original hair color was.) and her eyes a deep sapphire. She is of a slightly muscular build, so she wieghs slightly more than most girls her size. Evelyn's hairstyle never really changes; she always just lets her long, curly hair hang down behind her, past her shoulders, though rogue strands of hair will shift to her front at times. As for jewelry, Evelyn wears a woven black metal necklace that wraps around her neck twice, the pendant on the necklace being that of a white crescent moon, and she is never found without a certain hair clip: The clip itself is a shade of royal blue, and for decoration, the clip has two crescent moons side-by side. This item was given to her by her best of best of friends, and she cherishes it to no end.
From time to time, Evelyn will change up the style of clothes she's wearing, but she normally sticks to a pair of jeans and a tanktop; the shirt usually being white, and the pants some sort of blue denim.
Weapon of Choice:
While Evelyn usually sticks to her fists in a scuffle, if things get out of hand, she will wield her weaponry of choice: A pair of black, solid metal tonfa, which he keeps holstered on her belt, one on each side.
Evelyn is quick to start a fight, but she is beyond beginning a scuffle for a trite reason. While she may be quick to temper at times (Not quite as quick as Rin, though.), Evelyn will only participate in a fight to protect someone who doesn't have the means to do so themselves: She could be considered a bully for the bullies, to a certain extent. Back in her old school, she was considered the class delinquent by the majority of teachers, but she deigns to choose her battles, and her grades are halfway decent, so it's really an undeserved title.
And here's a reference for what Rin looks like as a fourth year: (Just a quickie sketch, since it's easier for me...) Rin
Just imagine her ears to be shaped like human ears.
