kyonko
A fan-created, widely popular, female version of Kyon. She is usually depicted as a petite girl, with a medium length or long ponytail, and wearing a slightly oversized cardigan sweater over her school uniform.
Example
The original design was a simple genderswap, with her being depicted as a relatively plain-faced, taller girl, with short hair, before reminders of the original Kyon's fondness for ponytails and petite girls turned them into inherent traits of the character.
