Costume is ソルジャーズメロウ, JP server only.
Disclaimer: I found the BG years ago from a certain website (can't remember the name). It was kinda gallery of texture for 3D objects iirc. This one was tagged/categorized/titled as scifi wall texture. Credits for the person who made the texture.

About my friend who I mentioned in my previous work.
Finally I can contact him and he is safe. I noticed that in 2014 he sent me an e-mail and fortunately his e-mail account is still active.
His facebook account was deactivated because he want to focus on his college study.
