This picture is kinda old, and the picture is old too, ha ha.
Before the "main arc" takes place Phil and Riko had a couple of friends and they formed some kind of "gang" together.
From left to right: Riko, Volas, Lena, Andrej, Loui and the guy who takes the picture is Tuck.
You can see were Phil is sitting too, there is a hint on the picture.
It's a pity Volas, Lena and Loui died. .... and we still don't know what happened to
Well, life goes on, I guess 8'D !
