Who is this?

[Angel's Prayer]

In Namine's sketch, denoted by the red circle.

Roxas?

[.:{S u t e k i~M i d o r i}:.]

Yup. We saw that picture in KH2, when Roxas went inside the White Room of the Mansion .I think thats Roxas, leaving The Dark city...but if im wrong, i think he is leaving from something.

[Zero Sora]

It looks like Roxas to me.

[Xidon]

It's Roxas, I think you have that same pic in the white room.

[Tragic Fall]

Yeah thats definently Roxas.

[I]

roxas. who else has that hair? and who else is that short?

[Angel's Prayer]

okay, so it's roxas, but where is he going/leaving from? It's a little too bright to be the dark city....

[Sunset Horizons]

It's Roxas, when he quits the Organization.

[~Axel_Riku~]

Yeah that is basically want it is. Roxas leaving the Organization to find Sora. Or his other half.

[Xehanort: 17]

Yeah, i think it's Roxas.

[Lilly]

That so sure. It Roxas. In the white room Namine use to drow about Roxas and Sora!

[Ichi TK]

Looks more like Demyx to me, but I know it's far more likely to be Roxas.

[Khaston]

Roxas leaving the Organization. Just before or after he talks to Axel I think.
