What anime does this guitar-playing redhead girl come from? I have numerous pics of this character and she seems to be a performer. I can't find any information on it. I have tried Google's reverse image search and had no luck.

What anime/visual novel/etc. does this come from?
It's from an old VN called Missing ~Itsuka Kitto~ (Missing ～いつかきっと～). VNDB says it's published in 1998.

Take a look at the girls' uniform. The red-haired also wears a choker and has some kind of antenna (ahoge) at the side of her head.
