Who's the girl in that guys bubble?

the guy looks like Kuruno Kei from GANTZ, I suspect that she is Reika, an Idol, Advertation Model, Filmstar.
In the earlier Stages of the Series he dreams of her, buys her Pinups, in short is a Fanboy.
During the Series they meet because of some totaly crazy happenings, and during their first "Assignment" together she falls in Love with him, but at that Time he is already engaged with a female Classmate of him.

This is what a typical japanese classroom looks like.

needs more inoue
