Uiharu Kazari ( 初春 飾利) from Toaru Kagaku no Railgun ( とある科学の超電磁砲)
I like her because she's a very cute loli with a nice flowerban on her head.
She also is a little shy and reserved but will do anything to protect Academy City.
She likes sweets like me and I think she'd be my best friend if she were real.
