I remember reading this summary where this guy enters a vr game with his friends? They became trapped in it or something and maybe gained some sort of special abilities? Thats all i remember for now and its not Amatsuki.
I know in Tsubasa: Reservoir Chronicle
there is a part where they are in sorta Virtual Reality but I am pretty sure this is not what you are looking for since it was only a part.1/2 Prince
is one but they weren't trapped.
Maybe you're looking for Not Lives
is one but I don't think he gets trapped if I remember.Gamerz Heaven!
Sorry I couldn't be more helpful.
I'll update if I remember anything.
