I'm pretty sure it was intended to be her. Urushihara has done parody artwork before. What evidence did you have that it wasn't her when you removed the tag, Memegui? The eyes are sort of wrong, but brown <-> yellow is a common variation with many artists/characters.
Er, I remember a discussion about that somewhere and it was concluded it wasn't her. Anyway, sleeves are too short, socks are white instead of black but most importantly the headband is wrong. There's no denying it looks like her but it's probably just a coincidence.
