An idea for an idol-character that's been flying around in my head for quite a while now:

A girl who doesn't really see herself as idol material due to her plain looks, with the short black hair, glasses and regular grey eyes, so she decides to spice things up a bit by getting coloured contacts to colour-coordinate and match her eyes to her outfits.

I literally have no info on her yet though.

//Edit: Thanks to Daelynnn she has a name now: Ayako (with surname, Ayako Saitou)
